ITT Interconnect Solutions is launching the VEAM CIR-M12 Databus connector that is designed for transmitting a variety of different data types between coaches in modern mass transit systems. In particular, customers in this sector requested a connector that bundled multiple Ethernet and MVB lines into a singular connector.
ITT ICS mounted its new Quadrax QXM12 contacts into FRCIR circular bayonet series connectors. With this design, four conductor wires and the associated braid from shielded cables are integrated into the QXM12 contact. A special plastic insert groups multiple QXM12 contacts and their cables into a single connector. With this connector, designers can incorporate data transfer from Ethernet, MVB, WTB and video lines, according to VG95234 (where applicable), within the same connector, handling diverse data feeds such as engine diagnostics, brake controls, environmental conditioning, passenger display systems, networking and lighting control.
The new CIR-M12 Databus connector contacts are rated at 3A (maximum current for 1ms is 10A); operating voltage is 100V DC and insulation resistance is 10Gohm. Mechanically, the insert is formed from thermoplastic material according to NFF16-101 – NFF16-102 and conforming to UNI-CEI 11170 (I2F2) and UL94-V0. The coupling gasket is made from silicone rubber, and other parts are produced in flame-retardant rubber. The metallic parts are aluminium alloy with a black epoxy-urethanic varnish that is RoHS compliant. The connectors withstand operating temperatures of -40 to +125degC.
