Reliable Push-In Relay Connections for Railway and Industrial Control
The Finder 94.P4.7SMA is engineered to provide secure electrical connections for compatible Finder 55.34T four-pole changeover relays. Its push-in spring-clamp terminals simplify wiring by allowing suitable conductors to be inserted directly into the connection points, reducing the need for repetitive screw tightening during control panel assembly.
The socket's design is particularly valuable in railway and transport-related equipment, where electrical connections may be exposed to vibration, mechanical shock and changing environmental conditions. Its compliance with applicable EN 45545-2, EN 61373 and EN 50155 requirements supports its use in appropriately designed railway electrical systems. The complete equipment assembly must still satisfy the relevant installation and certification requirements.
When fitted with a compatible Finder 55.34T relay, the socket provides connections for four independent changeover contact circuits and the relay coil. The removable relay arrangement enables straightforward servicing, while compatible jumper links and functional modules support organised, modular electrical control installations.
