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.

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

Summary

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.

Stringent requirements

As the number of participants in the field increases, so does the need to network them using information technology, equip them with appropriate electronics and interfaces for signal, data and power transmission, and shield them from harsh environmental conditions. Electromechanical interfaces play an important role here: they are the key to exploiting further miniaturization potential and making devices more reliable and flexible in industrial applications. However, dirt, vibrations, high temperatures and electromagnetic radiation place high demands on passive components.

Phoenix Contact responds to these requirements with a newly developed series of board-to-board connectors with 0.8 and 1.27 mm pitch. Both product families are ideally suited for the device-internal connection of several printed circuit boards. Thanks to horizontal and vertical variants, device manufacturers can implement mezzanine, orthogonal or coplanar PCB arrangements and thus offer flexible electronic layouts for different device applications.

Maximum freedom: Horizontal and vertical female connectors allow mezzanine, orthogonal and coplanar PCB arrangements

Full flexibility

All board-to-board connectors are designed for currents up to 1.4 A and voltages up to 500 VAC; and they offer solutions for 12 to 80 connection poles. Reverse polarity protection is particularly important in the compact pitches to prevent damage to the contact metals when they are mated and to ensure long-term stable connections inside the device. All board-to-board connectors are therefore polarized accordingly – the special geometry of the insulating housing reliably prevents female and male connectors from being mismatched.

Up to 500 mating and withdrawal cycles

The double-sided contacts of both product families make contact on the gold-plated rolled surfaces of the metals and thus guarantee an optimum contact force at all times, even under high shock effects of up to 50 g. Another advantage of the robust design: up to 500 mating and withdrawal cycles are possible without impairing electromechanical stability.

ScaleX contact system: The double-sided contacts provide high stability and allow up to 500 insertion and withdrawal cycles.

The unshielded Finepitch 1.27 series is suitable for stacking heights from 8 to 13.8 mm and, thanks to pre-assembled female connectors with flat ribbon cable, also enables wire-to-board applications, for example for larger PCB spacings.

The Finepitch 0.8 mm series offers particularly compact solutions for high-speed data transmission at up to 16 Gbps. Depending on the application and the required degree of protection, unshielded versions and versions with lateral shielding metals are available for maximum data integrity. Mechanically robust thanks to ScaleX technology. The hermaphroditically designed contacts of the more compact product series allow stacking heights from 6 to 12 mm. The newly developed ScaleX contact system not only guarantees particularly high mechanical stability. It also permits high tolerances for male and female connectors positioned differently for production or assembly reasons. The catch range of the Finepitch 0.8 series is ±0.7 mm per axis, the angle tolerances for mating are up to ±4 degree in longitudinal direction and ±2 degree in transverse direction. These high tolerances compensate the mechanical offset between the printed circuit boards.

Simple solution for SMT processes

The new board-to-board connectors of the Finepitch series are ideally suited for integration into the fully automated SMT process. Specially shaped and tin-plated gullwing surfaces offer a high contact area on the solder pads and thus improve the mechanical stability between the connector and the PCB surface. The soldering surfaces are designed in such a way that they still allow “overhead” soldering. This is always necessary when the printed circuit board is assembled on both sides. The unshielded versions also permit automatic optical inspection (AOI) and are delivered in a taped package for the appropriate process. Board-to-board connectors of the Finepitch 0.8 mm and 1.27 mm series offer ideal solutions for the flexible connection of several printed circuit boards in industrial electronic devices. The particularly robust contact systems allow different PCB arrangements and stacking heights and thus support flexible and modular device designs. Phoenix Contact is thus following the trend towards miniaturization and modularization of intelligence in the field. The great advantage for device manufacturers is that they can obtain tested and reliable device interfaces for the transmission of signals, data and power from a single source and can thus offer highly adaptive devices for the intelligent factory – regardless of the location and local market conditions.

Robust Connection

Board-to-Board Connectors for the Industry

In the past five years, hardly any other buzzword has driven the industrial production and automation sector like “the intelligent factory”. Otherwise diverse markets as the USA, Europe and China agree on the implications: Industrial production must become more networked, more efficient, more intelligent and thus more internationally competitive. Robust board-to-board connectors are an important step along this path.

Intelligent solutions for the intelligent factory: Board-to-board connectors allow connections in new dimensions

One of the drivers of a increased competitiveness should be enhanced versions of production resources that lead to higher performance, more flexible production lines and lower manufacturing costs. For the year 2020, various analyses forecast almost 20 billion (IDC, 2016), almost 30 billion (Gartner, 2017) or even up to 50 billion (CISCO IBSG, 2011) IT-networked “things”. Even the most cautious forecast means that in just two years there will be almost three times more things communicating with each other than people.

In addition to the ubiquitous smart devices, these things also include the intelligent devices of the industrial production: controllers, power supplies, I/Os, HMIs and many more. These devices themselves have become more intelligent in recent years. Their electronic components, such as processors, could be produced at substantially lower cost and thus became more powerful and numerous. Together with their components, industrial electronic devices themselves became ever smaller, more powerful and more numerous. As a result, more intelligence from a formerly central and strictly hierarchical unit moved decentrally into the field.

Miniaturized and Reliable: Board-to-Board connectors are used for the internal connection of printed circuit boards

Harsh Environment PCB Enclosure

From |

Selecting an enclosure is simplified by reviewing the sizes of the components & the PCB board that is to be enclosed, followed by the aesthetic look. However, when choosing an enclosure suitable for a harsh environment, the requirements become complex. Several things need to considered, such as how the enclosure is going to be mounted, whether the enclosure needs a vent, what is the degree of protection, what kind of test needs to be performed and many more.

Making a wrong choice can be extremely destructive, brand damaging and it also signals the end of the product.

What we can offer

Phoenix Contact presents new housings for electronics, for especially harsh ambient conditions. The robust housings of the Environment Case System (ECS) series with IP69 degree of protection are suited for a broad temperature range of -40°C to +100°C, and reliably protect the integrated electronics from physical influences.

Miniature Connectors

From |

Small yet high-powered connectors

Application specific and miniaturized connectors have come on rapidly. Fueling this rapid change is a combination of advances in technology. The control cabinets are getting smaller. This in turn reduces the available space for the devices and their boards. In addition, the functional density of devices is steadily increasing. Thus, PCB connectors must also be based on the new size specifications.

What we can offer

Phoenix Contact has launched two new 2.54 mm printed circuit board connectors: the FMC 0.5 and DFMC 0.5 connectors. It is designed to meet the miniature & quick connection requirement, boasting a compact plastic housing and push-in spring connection. The direct connection is possible for solid and flexible conductors with or without wire end ferrules. The wiring can be easily released without the aid of a screwdriver and the connectors can hold conductors with cross sections from 0.14 to 0.5 mm².

Figure 1. Low height profile – the FMC 0.5 connector family offers a push-in spring connection with spring opener.

This connector makes it ideal for designers who face the challenge of keeping up with the trend towards miniaturization.

The FMC 0.5 connector is a single-row connector with a height of only 5.4 mm whereas the DFMC 0.5 connector is a double-row connector with a low height of only 10.5 mm. Plugs in the same grid with push-in spring connection and spring openers that were previously available on the market were twice as high. Both connectors follow the trend of miniaturization – and the associated trend towards a high contact density in a small space.

It is designed for automated soldering processes (SMD and THR soldering processes). The two product families’ pin headers are made of LCP (liquid crystal polymer) plastic to withstand the high temperatures in the convection oven.

The applications for the two new connectors are extremely versatile. Possible target groups include measurement and control technology, automation technology and energy technology. Conceivable applications include controllers and inverters. The focus of the application areas is on industrial applications where signals are transmitted to the PCB.

Conclusion – the answer to new market requirements

The new FMC 0.5 and DFMC 0.5 plug connectors and the associated pin headers from Phoenix Contact meet the market requirements in the field of printed circuit board connection technology. Device manufacturers now get powerful connectors that require little space on the circuit board and in the device. For the end customer, the connectors also provide a quick, easy and convenient connection option. Processing in highly automated SMD processes is not a problem, and a gold-plated contact system provides additional security for the transmission of signals in industrial environments.

Importance of choosing the right PCB enclosure

From |

What is considered important when it comes to choosing the right PCB enclosure. Let us guide you through the process.

Price? Style? Service & support? Reputation of the supplier?

In the matter of fact, all of above are essential. The engineers should select the enclosure at first and then choice the mechanical & electronic components to suit the enclosure.
We need to consider

Material
The 3 common plastic enclosures are ABS, Polycarbonate, Polyester which are high functionality, light weight, flexible in design.

The Ingress Protection
The ingress protection classification DIN EN 60529 determines and rates protection against solid particle (e.g. dust) as well as liquid incursion.

The letters IP (ingress protection) is followed by a two-digit number; the first digit indicates the level of Solid particle protection and the second digit indicate Liquid ingress protection. IP Code

Environmental Considerations
How the enclosure will last over many years of operation depends on how well you evaluate the environmental impact of elements such as UV rays, temperature, airborne debris, etc.
Different materials offer varying degrees of impact resistance.

Dimensions
The internal and external dimensions of a PCB enclosure is extremely important. Sadly, in many cases, the PCB is chosen first and this makes it difficult for the engineer to source the best fit enclosure solution.

Modification of Standard Enclosures
The enclosure supplier may need to support modifications with value-added services that include drilling, milling, printing, color, etc. Some suppliers can even provide advance services like fitting membrane keypads, displays on the enclosure, etc as a complete solution.

Ease of Assembly
A complex PCB design may make it difficult to assemble electronic and mechanical components in the enclosure, which make is an important point to consider when selecting an enclosure.

Range of PCB Enclosure

Electrical Safety Starts from the Connector

From |

High Voltage WarningDo you know one common challenge for devices used in areas such as filter and inductor construction, energy distribution and power supply production is Electrical Safety i.e. how to lead the high power through the panel wall safety.

Finding the right wall feed-through terminal block to address electrical safety is a challenge as there are not many suitable solutions for high current and large wire cross-section. It is also unlikely that the manufacturers  will choose the feed-through terminal blocks as early as the design stage. This often leads to manufacturers designing their customized solutions out of sheer necessity; thus resulting in problems such as maintaining touch protection or insulating the current bar from the device housing.

The device manufacturers may also face problem obtaining the necessary certification for their devices. If the device is to be used worldwide, IEC 61800-5-1 and UL 1059 certifications are required. Many solutions in the market are unfortunately not adequately certified.

High Current Feed-through Terminal Blocks

Phoenix Contact offers an extensive range of high-current feed-through terminal blocks for various applications. You can find both pluggable feed-through terminal blocks and feed-through terminal blocks for permanent connections. The pluggable feed-through terminal blocks permit quick replacement and are thus service-friendly. In addition, the conductors can be preassembled. However, feed-through terminal blocks for permanent connections are more economical.

Do you know Phoenix Contact has been providing these feed-through terminal blocks for almost three decades?

Device manufacturers can choose the connection option to fit the application: fast push-in connectors, T-lox, conventional screw connectors, or simple bolt connectors. The connection areas range from 4 to 150 mm2 and the current-carrying capacity is up to 309 A.

These connectors come in standard and moulded designs, either with horizontal or vertical connection directions. The moulded version ensures high leakage resistance, even when a small amount of moulding compound is used. The product range provides various connection options for space-saving connections in all installation locations. This means that device manufacturers can flexibly select the connection type, direction, and cross section.
