UIC 558 Interfaces

HARTING UIC 558 Interfaces have two interfaces, with inserts offering space for 13 or 18 pins, and an additional solution with 22 pins and a PE for inter-car jumpers. The series offers interfaces for connecting remote control and data transmission lines to locomotive-hauled passenger trains. The lifelines of rail vehicles transmit data and signals for the remote control of lighting, the operation of door-opening systems, and the transmission of acoustic information and digital data packets. An important requirement of UIC 558 is that the interfaces must release automatically above a particular tensile force. This safety function causes the interface halves to separate non-destructively if two electrically connected vehicles move apart. HARTING UIC 558 Interfaces was developed to adopt Train Communication Network (TCN as in IEC61375) with an 18-conductor cable and connector. 13-wire plugs can be connected to an 18-pin socket, and the signals from the 13-wire cable can be carried through and the remaining five wires used for the Train Communication Network (TCN)-bus and side-sensitive door control.
