Fire protection helps to enhance security
Published: 11 July 2012 - Joe Bush
Belden's Lumberg Automation product program has launched a new range of connectors designed for use in the railway industry.
Complying with all international railway standards and fire protection requirements, including Hazard Level 2, the connectors offer security and can be used all over the world. They also offer vibration-proof M12 connection technology, industry protection class IP67 and a temperature range of -40°C to 90°C.
The connectors are offered as moulded ProfiNet or field attachable versions, and individual lengths of cable are optionally available for the field attachable connectors. This choice of versions means they can be employed in a range of solutions that include the networking of control modules for doors and air conditioning in trains. The shielded railway connectors can also be used in combination with IP cameras or infotainment systems.
Complying with EN 50155, IEC 61373 and DIN CLC/TS 50467 railway standards, the M12 connectors have four poles in D coding. The field attachable versions have threaded joints and spring type terminals enabling simple assembly. The molded versions are available with single or double ended ProfiNet cordsets. They also feature Cat 5 and Cat 5e transmission characteristics in line with ISO IEC 11801 and TIA/EIA-568-B.2
While the housings of the molded connectors are made of PA plastic, those of the field attachable versions consist of nickel plated die-cast zinc. The optionally available individual lengths of cable consist of irradiated, halogen-free polymer (FRNC) with a cross section diameter of 22 AWG. This also applies to the ProfiNet cable sets with molded connectors, which are offered in lengths of two, five or ten metres. Other cable lengths can be provided on request.
