Why Choose the Finder 40.31.7.048.0000 Miniature Relay?
The Finder 40.31.7.048.0000 is a compact and reliable miniature electromechanical relay designed for switching electrical loads in industrial controls, automation equipment and electronic assemblies. As part of the established Finder 40 Series, it combines a sensitive DC coil with a single changeover contact and a space-efficient PCB footprint.
This monostable relay provides dependable electrical separation between its control and load circuits. It offers an 8 mm coil-to-contact clearance and creepage distance together with 6 kV impulse withstand voltage, supporting reliable operation in demanding control applications. Its standard silver-nickel contact material is suitable for a broad range of general-purpose switching duties.
With a 48 V DC sensitive coil, a 10 A rated contact current and an SPDT changeover configuration, the 40.31.7.048.0000 is suitable for switching control circuits, resistive loads, lighting and small motors. Its 3.5 mm contact pin pitch allows direct PCB mounting or installation through a compatible Finder 95 Series socket.

Reliable Switching for Control and Automation
Electromechanical relays such as the Finder 40.31 allow a low-power control signal to switch a separate electrical load while maintaining galvanic isolation between the circuits. The changeover contact provides both normally open and normally closed switching paths, offering flexibility when designing control boards and automation equipment.
The sensitive coil reduces control-side power demand, while the relay’s compact dimensions make efficient use of PCB space. Compatibility with Finder 95 Series sockets also provides installation options for applications requiring easier relay replacement and maintenance.
Typical Applications
- Industrial control and automation equipment.
- Printed circuit boards and electronic assemblies.
- Machine control interfaces.
- Lighting and resistive load switching.
- Small single-phase motor control.
- Timers, control panels and interface modules.
