Reliable Single-Changeover Relay Connections for Industrial Automation
The Finder 95.03SMA relay socket provides a secure electrical and mechanical interface for the Finder 40.31 general-purpose relay. Its five connection positions accommodate the relay coil and the common, normally open and normally closed terminals of its single changeover contact. This makes the socket suitable for control circuits requiring a compact, removable switching relay.
When a compatible Finder 40.31 relay is installed, the relay contact changes state when its coil is energised. This allows the connected circuit to switch between normally closed and normally open paths, making the assembly useful for equipment control, auxiliary signalling, interlocking and other suitable automation functions. The actual switching capacity must be checked against the installed relay's ratings and the connected load.
The box-clamp screw terminals provide reliable connections for appropriately sized conductors. With support for both 35 mm DIN rail and panel mounting, the socket can be integrated into new electrical cabinets or used when maintaining existing relay installations. The supplied metal retaining clip helps secure the relay, while the plug-in arrangement enables convenient replacement after the circuit has been safely isolated.
Selected Finder 99.02 indication and EMC suppression modules can be used with suitable relay and socket combinations to provide visual coil indication or help manage electrical interference. Compatible Finder timing accessories may also be used where the complete assembly supports the required timing function. These accessories are separate from the basic socket and must be selected according to the relay coil voltage and application.
For installations containing multiple compatible sockets, the Finder 095.18 8-way jumper link can simplify the distribution of common connections. Identification accessories also support clear circuit labelling, helping electrical engineers and maintenance technicians locate and service relay interfaces efficiently.
