ITT’s Interconnect Solutions, a leading global manufacturer and supplier of connectors, interconnects and cable assemblies, has developed a new lightweight VEAM Rectangular Plastic Connector for mass transit applications. A replacement for the relatively large and heavy metal connectors previously used inside train cabins and carriages, the lightweight VRPC Series combines a small form factor with a robust design for easy integration to replace older, obsolete connectors.

The VRPC Series connector design is up to 80% lighter and 30% smaller than traditional metal interconnects. The IRIS-compliant VRPC Series can be sealed to IP67 or unsealed depending on the specific application, and is rated to Railway Standards NFF 16-101 and NFF 16-102 for both fire and smoke resistance. An innovative grommet system dispenses with the need for filler plugs to meet sealing requirements.  The VRPC also features a flexible cable support that doubles as a panel-fixing device.

VRPC Series connectors employ ITT’s proven Trident contact system and are available in 3-, 6- or 12-contact layouts. Contacts are turned to maintain signal continuity in high vibration rail environments. Polarization can be set during connector assembly and a snap-in mechanism provides audible confirmation of correct mating for ease of use in restricted spaces. 

“The compact, lightweight VRPC Series plastic connector will benefit numerous applications that require a lighter component without sacrificing performance,” said Mike Gardiner, product manager at ITT. “The added benefit of being tested within harsh conditions satisfies numerous government regulations for quality assurance and will be a more environmentally appropriate design choice.”

Suitable applications for the VEAM Rectangular Plastic Connector range include air conditioning controls, doors, fire control systems, LCD displays, signalling, wipers, shutters and seats on mass transit vehicles.
