The Only Constant is Change

From |

It has been approximately three months since the Covid-19 outbreak affected us globally. The Covid-19 crisis has brought misfortune to some industries. However, some have unexpectedly benefitted from the situation, for example: mask and sanitizer manufacturers.

Have you ever thought that Working from Home (WFH) will be something necessary before the outbreak? This difficult situation of Covid-19 has affected much of the way we work, how we work with our clients, and even how we manage to maintain relationships with our family and friends (including our customers and suppliers). I personally felt overwhelmed when my company first applied the WFH policy. Professionally, I was not sure if I could be productive and work effectively from home. I also had to find practical ways to communicate with my supervisor, in order to ensure that he could always get the latest updates on my work progress. Personally, I am worried about how I can protect my own health and that of my family from this contagious virus.

May is often celebrated as Mental Health Awareness Month. Through this blog, I would like to share 3 points that can hopefully remind us to always be always grateful amidst this difficult Covid-19 pandemic.

1. More Personal Time

Let us be honest. When we’re busy with our travel schedule or appointments, we sometimes forget to plan for our own personal time. With WFH, we actually can have more personal time to ourselves. We may enjoy our own personal time by watching movies or reading those books on the shelves which we have not had the time to complete before.

We can also do some self-reflection and self-development. As we are supposed to stay at home most of the time, we might find ourselves learning to unlock new skills, such as video editing, hosting virtual meetings, or even our cooking/baking skills!

Not to forget, now we also have more time to exercise. We tend to find excuses not to go to the gym after working the whole day. As we do not need to commute to our workplace anymore, we have plenty of time to keep our body fit.

2. Precious Bonding Time

When was the last time you really spent quality time with your family members other than on weekends (if you do not have any appointments with your friends)? For countries with lockdown measures like Singapore, Malaysia, and the Philippines, you are required to stay at home with your family nearly 24/7, with the exception of going out to buy essentials. We can see what our kids/parents/siblings or even pets are doing the whole day! While some of their lifestyle habits may surprise you (E.g. your kids write the letter x in a different way than you do), this might be the perfect time for us to have precious bonding time with our partners at home.

If you miss your friends, you can always just call them instead! Video calling our friends virtually might seem awkward at the beginning, but as time goes by, you will find yourself comfortable with it. Video calling our dear friends might now be the perfect way to catch up with them.

3. The New Normal

For those whose companies are applying the WFH policy, I would like to congratulate you! Many front-line workers do not have the chance to do that, and we should appreciate their honourable act of fighting the pandemic outbreak. For us who are told to stay at home, let us be grateful as the new normal is currently here at your doorstep.

We are officially more flexible now! Although we opt to find new solutions in order to be productive while we are working from home, we can actually adjust our activities according to our own needs. We can work from our own beds wearing pyjamas, also at our own preferred timing. We may also set our own preferred music for the purpose of our own entertainment.

Moreover, by doing frequent virtual discussions or meetings with our teams or managers, we might create an unusual bonding which might not have occurred if we meet face-to-face in the office. This bonding or connection will undoubtedly be beneficial when it is the time for us to be back in the office.

To conclude, we must understand that this crisis is beyond our control and it is important to look at the silver lining. We have to stay positive, and being positive can help maintain our mental health. Although we still cannot predict when this pandemic will be over, it is part of our social responsibility to motivate our friends & family by looking at the current issue in a positive way. Just like the old proverb: “When life gives you lemons, make lemonade”!

Safety in Tunnel Applications

From |

Commuting each morning via the 12km road tunnel during peak hours, it only takes a little more than 15 minutes to reach my destination from home. It is difficult to imagine thousands of cars passing through each day without hearing many accidents being reported on the news. However, when calamity arises, it is then clear that the safety systems have been put in place, ensuring the safety of road users at all times.

Have you ever wondered what is going on behind the scenes?

The road tunnels are designed in accordance with directives which specifying the minimum safety requirements. Aside from the emergency exits and emergency telephones available at regular intervals, it is paramount that the tunnels must always be supplied with power, light, fresh air and water for firefighting.

Take the ventilation system for example. It helps to remove toxic gases when the NOx, CO or CO2 levels are detected to be high during normal operations. In the case of a fire, the operator depends on the same system to purge the smoke and heat from the tunnel, away from motorists evacuating the tunnel or the emergency response team that is tackling the disaster.

To minimise potential casualties, Phoenix Contact has developed the Dynamic Evacuation Guidance (D.E.G). The automated D.E.G comprises of a full redundant configuration, where the guiding handrail is monitored by a pair of redundant PLC to guarantee maximum availability. Together with its 2-hour phosphorescence effect on the guiding handrail, the worst-case scenario during a loss of electrical power is also mitigated.

It is equally important to note that all state-of-the-art safety systems will not be operating at its best without a reliable communication network. The integrated backbone communication network is typically setup in several redundancy levels. At “switching level”, the entire tunnels are segregated into various “zones” covering certain sections of the tunnel. These “zones” are then grouped together through the “routing level”. With this structure, network failure (should it ever occur) can be isolated, without affecting other parts of the communication network.

6 Reasons Why Phoenix Contact PLC-Interface Relay Is No. 1 in the Market

From |

An experienced electrical engineer will be very familiar with compact relays. There are plenty of brands in the market and they are essential in many applications. Today, we are going to share with you why Phoenix Contact PLC-Interface relay is the cream of the crop.

  • High reliability by having no soldering points

Unlike most compact relays in the market, Phoenix Contact PLC-Interface relay is made up of a single metal stamp circuit without any soldering points. Soldering joints are generally lower in strength and are advised to be used in high temperature applications. Corrosion might happen if the flux residue is not removed. Thus, by removing the weak solder points, we increase the reliability of our PLC-Interface relay.

  • Push-in Technology increases efficiency

We cannot imagine the time without Push-in Technology. It saves up to 80% wiring effort as compared to the good old screw connection. It was first implemented in Phoenix Contact terminal block and has slowly taken over as the preferred connection technology in most of Phoenix Contact products. Using a simple spring mechanism with a striking orange button, Push-in technology has won the hearts of many users. It is now available in PLC-Interface relay.

  • Compactness and modularity saves space and reduces downtime

Real estate in the control cabinet is extremely precious. We are always trying to fit as many components as we can into the smallest possible control cabinet. With just 6,2mm thickness, you can fit over 160 pieces of PLC-Interface relay on a 1-meter DIN rail. By keeping the control cabinet small, you can save on the material cost. The modular system also ensures easy replacement of the relay in case of wear and tear. The pluggable relay reduces downtime needed for repair and maintenance.

  • Wide variety of accessories provides ease of wiring

Phoenix Contact PLC-Interface relay comes with many accessories such as built-in bridges for convenient distribution. This makes installation and wiring faster as compared to doing it manually with wires. We also have a wide range of marking materials for easy and appropriate labeling of the relays.

  • High availability with solid-state relay and other features

Solid-state relays are almost wear-free as they do not rely on mechanical movement to perform the switching. This gives the PLC-Interface relay a long service life. With integrated circuitry, PLC-Interface relays are protected against reverse polarity. Safety is further enhanced with the safe insulation between input and output (EN 50178). PLC-interface relay works well even in harsh and aggressive conditions. Rated IP 67, it is resistant against moisture and dust.  

  • We make smart relays smarter with PLC logic

Phoenix Contact is the pioneer to combine logic, interface and field connection. It gives the device the ability to switch and control the I/O signals, and combines the relays with analog modules. All can be achieved by simply plugging in a small controller into a standard PLC-Interface. With the width of 50mm, the small module provides up to 16 I/O signals. Extension modules can be added to increase up to 48 I/O signals. An intuitive software, Logic +, is also available for quick programming of the logic relay system.

Besides PLC-Interface relay, Phoenix Contact provides the best switching devices for all applications. To know more about the switch devices we have to offer, feel free to contact us at!

A World Without Sensors, a World Without Internet of Things (IoT)

From |

Sensors are not only used in industrial applications, but they are used widely around the world, in our everyday lives.

Sit back, close your eyes, and think. “What would the world be like, without Sensors?”

Just to name a few applications on things we commonly come across: Our mobile phones have light sensors; automated car parks have proximity sensors; thermometers have temperature sensors; cameras have motion sensors; smart watches have accelerometers; cars have pressure sensors etc.

The Internet of Things is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction. IoT could be anywhere and everywhere nowadays, ranging from daily household products such as refrigerators, to life saving products such as heart rate monitors. This blog article will let us understand the importance of sensors in applications of Internet of Things (IoT). Without sensors, there will be no IoT.

Why are sensors so important to IoT? Sensors read real time information, which translates into data. This data will be translated into knowledge, and follow-up actions can be taken. This will in turn result in: better labour efficiency and energy savings, as lesser natural resources are required for manual labour; cost savings in terms of labour, and lower equipment maintenance costs as any minor issues will be highlighted before major ones strike; space and time savings as inventory will be better managed due to automated analysis and reporting.

As good as IoT may sound, there are challenges and constraints which IoT faces. Low power consumption is always a challenge, as the devices are usually not easily accessible, and need to run for long lifetimes with minimal power consumption. We can relate this to having high quality power connectors as the reliability of the connections need to be of high standards. When a connector fails, or in a worse case creates a fire, the after effects will be devastating as the whole plant or office might actually be lost before any fire fighters arrive, due to the distant location of such IoT applications.

In the following exhibit from McKinsey Global Institute, it is possible to see IoT’s potential benefits and challenges across the global economy. With sensors that allow device monitoring on health and wellness, to manufacturers that utilize sensors to optimize the maintenance of equipment and protect the safety of workers. From McKinsey’s analysis of the applications along with the corresponding size estimates, IoT has a total potential economic impact of $3.9 trillion to $11.1 trillion a year by 2025. This is an amount estimated to be about 11 percent of the world economy.

With this relatively huge amount of potential in the market, it is a great time for sensor companies to start working with connector companies to ensure that the upcoming production for their sensors are of quality with quality power connectors and enclosures.

In what ways can Phoenix Contact connectors and enclosures cater to the Sensor industry’s needs? As per the following pictures, we do have 3 product families that can cater to the needs of industrial usage.

Our above product families can be designed into various types of sensors, such as:

Image sensors, Biosensors, Pressure sensors, Chemical sensors, Load sensors, Position sensors, Temperature sensors, Level sensors, Flow sensors, etc.

When Power Distribution Meets Push-in Technology

From |

QPD, which is short for QUICKON Power Distribution, is the brain child of Phoenix Contact. Since its launch, it has been well received by many customers in the lighting industry. As the name suggests, it provides easy and efficient power distribution through QUICKON, also known as insulation displacement connection.

QPD consists of a huge variety of connectors such as a 1-in-3-out distributor and cable extender, which offers the flexibility and convenience needed when laying power cables for various lighting infrastructures. Granted that QPD is made of plastic and is very lightweight, it provides up to Ingress Protection (IP) 69k which basically makes it submersible.

However, Phoenix Contact did not stop there. With the increasing popularity of automation, many companies want to minimize manual work. While QUICKON is a fantastic connection technology, it has limitations when comes to automation.  It is neither easy nor cheap to design a machine that could automate cable termination via QUICKON.

Thus, we made the great product even BETTER.

IPD (Installation Power Distribution) designed with Push-in technology, is optimized for automation. As Push-in motion is simple and linear, it is easier and more economical to design a machine to automate the insertion of stranded cables with ferrules/solid cables via Push-in technology. The removal of cables works the same as Phoenix Contact’s Push-in terminal block. Push in the classic orange release button with a screw driver to open up the cage within the connector and gently pull out the cable.

IPD is the perfect panel feed-through for lighting connection and has up to IP 67 protection which is suitable for use with outdoor lightings. IPD comes in classic white, which blends in seamlessly when installed on lighting devices. No hassle is needed to tuck the connector away – it could be installed in plain sight and would still look good.

Sensor Actuator Cabling for Smart Manufacturing

From |


Machine building has evolved greatly over the years. Traditionally, it was classified under heavy industries, usually on a smaller scale and served mostly local or regional areas. However, as a result of the industrial revolution, machines became larger and more complex. The process of producing machines had also become more complicated as well.

Automation is adopted to reduce the production cost and increase productivity. It also lessens the reliance on labour and improves the reliability and quality of machines. All the above mentioned qualities are needed for modern day machine makers to stay competitive in the market.

Data acquisition becomes crucial. In machine building, data such as temperature, pressure, speed and proximity etc. can be attained via sensors. These sensors collect information and send them back to the control system.

In the beginning, the sensors were wired directly to the control system without any organisation. This method of connection is messy. It also makes troubleshooting and maintenance difficult as it is challenging to isolate the defective sensors when a fault occurs. In addition, this way of connecting sensors requires a large amount of cables, leading to increased manufacturing cost of the machines. In many cases, cables take up the bulk of the cost involved in the set up.

As a result, more and more machine builders start to adopt sensor and actuator cabling.  In sensor and actuator cabling, the sensors are connected to a distribution box via circular connectors. The distribution box is then connected to the control system via one master cable. Sensor and actuator cabling greatly reduces the amount of cables required in a set up. It also makes troubleshooting and maintenance easier. There is a LED light indicator (which turns red when a malfunction occurs) and a labelling option (for easy identification of the sensors) for each sensor on the distribution box.

Phoenix Contact offers a wide range of products, from distribution boxes to self-assembled connectors, for sensor and actuator cabling. The self-assembled connector comes with different connection technologies to minimise the installation time and eliminate the use of special tools. We advocate choosing the connection technologies based on your applications. Phoenix Contact had also incorporated the famous Push-in Technology into the self-assembled connector. It could be used with or without ferrules, depending on your preference.

If you prefer pre-fabricated connectors, Phoenix Contact can also cater to your exact needs. We offer different cable materials, from polyvinyl chloride (PVC) to high specification robotic cables of customisable length and a wide variety of header types. Other customisation options such as colour, printing and labelling can be done as well.

Furthermore, Phoenix Contact has a wide array of accessories such as distributor connectors, adapters and valve plug connectors as we strive to be the one-stop provider for sensor actuator cabling solutions.

Direct Connection Adaptivity

Connect adaptivity directly: SKEDD direct connection technology brings new flexibility to device design

SKEDD direct connection technology makes device design more flexible

Whether modern climate and ventilation systems in building technology or compact controllers in classic industrial applications, intelligent automation structures require functionally embedded systems. This poses a challenge to device manufacturers to develop universally operational solutions for specific tasks and ambient conditions. SKEDD direct connection technology revitalizes PCB connection technology.

The first direct connector in the world with Push-in spring connection allows application-specific device designs with just a few PCB layouts

Increased device flexibility – that is to say, adaptability – means that fewer versions need to be produced and made available – and overall unit costs are lower. PCBs and connection components are the central nervous system of electronics and as such have a large impact on the performance and flexibility of electrical devices.

More flexibility thanks to SKEDD

The innovative direct connection technology SKEDD –Swedish for “it happened” – makes direct pluggable and detachable PCB connections at any position on the PCB possible for the first time. The SKEDD connector types SDDC 1,5 and SDC 2,5 from Phoenix Contact no longer require headers – they can be plugged in via tin-plated through-connection bore holes by hand. The advantage: In the past, the electronics manufacturer needed to combine application-specific connection technology such as PCB terminal blocks or headers with the PCB using an irreversible soldering process. This largely dictated functionality of the PCB and the overall device. SKEDD direct connection technology makes this process unnecessary; only the corresponding bore holes need to be provided in PCB manufacturing process. In this way, the PCB does not become thermally loaded again.

Currently, many PCBs are processed first in the SMD method, and PCB terminal blocks or headers are soldered on as the second step in the wave soldering process. If the second soldering process is removed, the operator saves process and component costs. This also makes all logistics and materials planning for the headers unnecessary. Equipment costs and feeder space requirements are also reduced when using the SMD soldering process. Accordingly, there is more space for additional components when the header is omitted using the SMD process. In an ideal case, additional modules can even be produced on a single system without conversion.

Reliable mechanical connection

Both PCB and device manufacturers see immediate benefits from this technology. In addition to saving costs, they are now able to use a single PCB layout for different device designs – and still implement flexible application-specific connections for signal, data or power transmission.

Single- and double-row direct connectors offer solutions for countless applications such as climate control systems, smoke and fire alarms or large household appliances

SKEDD contacts are an improvement on press-in technology, and they place no special requirements on the PCB. The contact zone consists of two flexible contact limbs that are easy to bend outward and that are adapted optimally to the plated-through bore holes. When inserting the contact into the bore hole, the contact limbs are pressed together – thereby ensuring a secure mechanical and electrical connection. Lateral body-bound rivets on the connector increase the mechanical stability as well. The interlock is designed for standard PCBs with a thickness of 1.6 mm and allows for up to 25 connecting cycles.

SKEDD contacts consist of two flexible contact limbs that are easy to bend outward and that are adapted optimally to the plated-through bore holes

Tests in accordance with the railway equipment and household appliances standards

In addition to the required approval and qualification tests, the SKEDD direct connectors from Phoenix Contact meet the highest requirements of mechanical and electrical safety. The series SDDC 1,5 and SDC 2,5, for example, are qualified for special fire protection requirements in accordance with DIN EN 60335-1 (“Household and similar electrical appliances – Safety”). Included in this standard are household appliances such as dishwashers, washing machines and portable cooking appliances, drives for awnings and blinds, heating units, climate systems and heat and cooling circulation pumps in private and commercial areas.

Two tests prove the capability of the electrical components and the polyamide insulating material used. First, a glow-wire with a temperature of 850 °C is applied to the material for 30 seconds. The Glow-Wire Flammability Index(GWFI) test is successfully passed if the test plate continues to glow less than 30 seconds after removing the glow-wire. The second test establishes the Glow-Wire Ignition Temperature (GWIT). For this test, a glow-wire with a temperature of 775 °C is held to the plastic test plate. The material may glow briefly, but for less than 5 seconds, and it may not ignite.

The SDC 2,5 single-row connectors are also qualified and approved for PCBs with HAL surfaces (Hot Air Levelling, surface protection) in accordance with DIN EN 61373 (“Railway applications – Rolling stock equipment – Shock and vibration tests”). These standards place high demands on the vibration-proof and shock-proof capabilities of devices and components used in trains. For this test, the connectors were exposed to 15 hours – five hours per spatial axis – of random vibrations with a frequency of 1 to 150 Hz and an effective acceleration of up to 5.72 m/s². Interruption of the contact may not exceed 1 µs during this process.

A wide range of solutions

The standardized tests attest to how reliable the direct connection technology functions, even under demanding ambient conditions and high safety requirements. SKEDD direct connectors are suited for classic industrial applications as well as for applications in building automation and railway technology.

The SDDC 1,5 and SDC 2,5 product series from Phoenix Contact offers solutions for countless applications such as climate control in rail vehicles, smoke and fire alarms or large household appliances. Both series feature tool-free push-in spring connection: This means that both solid and stranded conductors with ferrules can be connected without opening the clamping space. The integrated test points enable convenient function checks when loaded. Designed for conductor cross sections up to 2.5 mm², the single-row SDC 2,5 direct connectors are suited for currents up to 320 V. The double-row connectors from type SDDC 1,5 offer an efficient connection solution specifically for signal densities that are often high in measuring, control and regulation technology.

SKEDD direct connectors are suited for backside PCB connections, for example, or for internal device wiring


Tool-free, reliable and process-efficient – the combination of Push-in spring connection and SKEDD direct connection technology offers new flexibility in device wiring. SKEDD connectors do not require headers and can be plugged in directly by hand in tin-plated through-connection bore holes. This enables PCB and device manufacturers to implement countless device designs with application-specific connections for signals, data and power using just a few PCB layouts. Various tests have proven it: Whether for applications with high vibration requirements like railway technology or with special fire protection requirements like in household device technology – direct connectors with SKEDD technology are an interesting new solution.
