Why Choose the Finder 97.51.7SMA Relay Socket?
The Finder 97.51.7SMA is a 5-pin, single-pole relay socket with screwless spring-clamp terminals, designed for compatible Finder 46 Series industrial relays. Part of the Finder 97 Series, this railway-oriented socket provides a practical electrical interface for control panels, industrial automation systems and relay-based switching applications.
Featuring a 10 A current rating, 250 V AC voltage rating and compact 15.8 mm housing width, the Finder 97.51.7SMA combines reliable relay connections with space-efficient installation. Its spring-clamp terminals allow conductors to be connected without conventional screw tightening, while the socket can be mounted onto a standard 35 mm DIN rail.
The 97.51.7SMA is associated with the Finder 46.61 single-pole changeover relay and is suitable for installations requiring a railway-oriented socket variant. The SMA suffix identifies a metal retaining clip configuration, helping secure the relay during operation while allowing replacement during maintenance. The socket also supports compatible Finder 99.02 indication and suppression modules and Finder 86.30 timer modules.

Reliable Relay Connections for Industrial Automation
Industrial relay sockets provide the connection interface between removable plug-in relays and permanent electrical control wiring. The Finder 97.51.7SMA is designed for compatible Finder 46.61 relays, supporting single-pole changeover switching in automation, signalling and auxiliary control applications. Its spring-clamp terminals help streamline wiring, while the removable relay arrangement supports convenient maintenance without disconnecting the permanent socket wiring.
The Finder 97 Series also accommodates compatible 99.02 coil indication and EMC suppression modules and 86.30 timer modules, allowing additional functions to be incorporated where required. With its 10 A / 250 V AC socket rating, compact housing and DIN rail mounting, the 97.51.7SMA is suitable for organised relay installations in industrial and railway-related control equipment. The selected relay and complete assembly must be checked against the application's electrical and environmental requirements.
