Stäubli upgrades MPC rail industry connector system
S
täubli Electrical Connectors has upgraded its MPC range of rail industry modular power connectors as part of
its process of continuous improvement. The enhancements include new generations of straight and right-angled connectors. The insulators in the new ranges are
made of improved plastics that provide increased insulation resistance of up to 15kV and a lower degree of flammability. They meet European rail applications standard EN 45545-2, including the most stringent HL3 R23 hazard level class for underground and high speed trains. The insulation, combined with a new
zinc die-cast alloy used for the side elements, has allowed the units to be more compact, with weight reductions of up to 30 per cent over previous models while remaining 100 per cent compatible. “Developers of rail vehicles,
particularly for light railways, are always looking for components that are lighter and more compact to create more usable space for passengers,” says UK
managing director Selwyn Corns. With ratings of 3600V and up to 700A, the units can be used for connecting transformers, traction motors, inverters and batteries as well as power links between carriages. The use of application-specific
connectors enables faster connection and disconnection than with individual connectors, helping to shorten maintenance and repair times. Up to 15 single pole power contacts can
be combined, with up to five joined side by side in up to three layers. The linear versions are flat, making them particularly suited for under-floor mounting. The MPC is vibration and shock tested
in accordance with EN 613731 and is corrosion resistant (240h salt mist test in accordance with EN 60068-2-112). It is rated at IP69K when mated and provides over 500 mating cycles. A range of compatible insulators is available for various contact diameters, and cable cross- sections from 10 to 240mm2 are accepted.
The enhancements include new generations of straight and right-angled connectors Two screw connections with M8 or
M10 thread are now available, depending on the size, so that a grounding cable can be connected. The stainless steel guard, previously riveted to the insulators, can now be easily clipped in place without the use of
tools. Although designed for railways, metros and tramways, the connectors can be used for other high current, high voltage applications where long-term reliability is crucial.

Harder, Better, Faster, Stronger T
he connectors used in the railways are installed across challenging terrain and exposed to unexpected
environmental extremes. Regardless of those challenges, the trains should run punctually, efficiently and safely. Therefore, the connectors used in the railway industry are required to meet the highest safety and standards to ensure that they perform consistently and withstand extreme temperature, humidity and other potential risks. Mencom offers a wide range of versatile
interconnection solutions for the railway and mass transit industry. Not only are they shock, vibration and corrosion resistant whilst providing the top performance and reliability with a proven track record, but also fully compliant with all relevant railway standards as well as fire and smoke requirements. The railway connectors are used for data transmission along tracks, passenger rolling stock equipment including brakes and controls, signalling systems, and power transmission on trains and track systems. Mencom M12 circular connectors are
rugged, compact, durable, and sealed. This pre-assembled solution is especially ideal to withstand a variety of severe environmental, industrial and chemical conditions. In addition, Mencom M12 circular connectors are highly configurable while featuring an IP67 rating and optional shielding. The keyway codings are available in A-coding & B-coding (Actuator-sensor

plug, DeviceNet, IO link and Profibus) and D-coding (Industrial Ethernet, Ethernet/ IP for Railway Applications). Custom solutions are also availalbe to meet unique specifications of the railway. Mencom M12 connectors are UL listed. For the electrical railway applications
which demand higher voltage and amperage ratings, Mencom offers the rectangular multipole connector solutions. They are comprised of two parts; inserts and enclosures. Inserts for multipole rectangular
connectors are made of self-extinguishing thermoplastic resin UL 94 V-0, normally used for applications in a maximum ambience temperature of 125 degrees celsius. The end user can choose a wide range of inserts based on the requirements of the railway applications such as the rated voltage (from 50V to 5,000V), the rated current (from 5A to 200A max), the number of poles, and the different load combinations required (power and signal poles within the same insert). The inserts are approved in accordance with the approval marks including UL, CSA, CQC, GL and EAC. Various enclosure versions are offered
with different combinations of body and coating materials to protect connections in the harsh environments. The enclosure series is available for normal environment, high temperature environment, aggressive environment, and environments that require electromagnetic compatibility. In

order for the coupling stability and enhanced protection against accidental opening, the enclosures are equipped with single or double closing devices featuring levers, springs, or pegs. Sealing is assured by special gaskets that protect the contact groups inside the enclosures against dust and aggressive agents even under impacts and strong mechanical stresses. In general, the coupled enclosures guarantee IP44, IP65, IP66, IP67. However, IP68 or IP69 (IEC/EN 60529) are achievable with IP68 or E-Xtreme enclosure series. EN 50155 is a widely recognised international standard for electronic

equipment used in any railway application. This standard covers aspects of this electronic equipment including temperature ranges, humidity, shock resistance, vibration resistance, power supply, electromagnetic interference/susceptibility, power surge, electrostatic discharge (ESD) and transient factors. Mencom railway-certified switches combine the powerful platforms of industrial Ethernet switches and all of their advanced features in a robust and reliable unit.
