Connectors for Rail Applications

Smiths Interconnect’s REP seriesSmiths Interconnect’s REP series multipole, sealed, plastic connectors, provide a quick and secure connection of embedded equipment across a wide range of applications for rail, such as sensors, brakes, lighting, air conditioning, and communications. The connector is available with the proven Hypertac hyperboloid contact technology which guarantees excellent reliability, even under high levels of shock and vibration and allows up to 20,000 mating cycles and high current rating up to 18 A. REP connectors are also available in the EasyREP version, using MR screw machined contacts and allowing up to 500 mating cycles. The REP connector range offers crimp termination contacts for cable harness applications and straight or bent termination contacts for PCB mount applications. Both versions are available in 2, 6, and 12 ways. The REP Series comes with a shunt accessory enabling electrical derivation inside the connector for transmission of information to different locations. Just one contact is needed for cables with cross sections from 0.5 mm² to 2.5 mm² (20-13 AWG) per the NFF 63-808 and EN 50-306 standards. No specialized tooling is required for mounting, with consequent reduction of supply chain, maintenance, and cabling costs. For easy mounting, the connector includes polarized guides and provides several configurations: cable-to-cable, clips, front and back panel mount. Connectors are available for delivery as a complete, tested pre-cabled solution according to customers’ specifications and are also suitable for the industrial, Test & Measurement, automotive, public works, and defense industries.

HARTING’s new Han HPR VarioShellHARTING’s new Han HPR VarioShell was developed as a highly flexible housing system especially for inter-car jumpers. The design of the Han HPR VarioShell has been developed with the requirements of customers in mind. The shape of the cover ensures an optimized flow for water, dust, and dirt to protect the screws from environmental influences. A special contour on the back of the housing ensures that ice can expand behind the housing. This lessens the stress on the housing, leading to a longer lifetime. The two-piece housing achieves IP69K using a counter pressure frame, thanks to the all-round internal seal. The removable cover makes it possible to equip the housing from the interior of the vehicle as well as from the outside. Cables can easily be routed through the wall for shorter cable runs and, therefore, less weight. Easy accessibility also reduces the effort required for operation, service, and maintenance. Not all connections have to be interrupted in the event of a fault. Instead, it is possible to open the housing cover to identify and replace the faulty conductors or contacts. The Han HPR VarioShell is an open system that additionally provides counter pressure frames, cable managers, and shielding plates to guide and intercept cables of different diameters. The new housing system can be used as a classic surface mounted housing or bulked mounted housing – and forms a robust alternative for distribution boxes, for example on the roof of the vehicle, on the outside wall, or on the bogie.
