40.31.7.036.0000 Finder Miniature PCB relay 1pole 10A DC 36V
Finder 40.31.7.036.0000 is a 10 A miniature electromechanical relay with one changeover contact, a sensitive 36 V DC coil and PCB or socket mounting.
Why Choose the Finder 40.31.7.036.0000 Miniature Relay?
The Finder 40.31.7.036.0000 is a compact and reliable miniature electromechanical relay designed for switching electrical loads in industrial control, automation and electronic equipment. As part of the established Finder 40 Series, it combines a single changeover contact with a sensitive DC coil and a space-saving enclosure.
This monostable relay provides dependable galvanic isolation between its coil and contacts, including an 8 mm clearance and creepage distance and 6 kV impulse withstand voltage. Its cadmium-free silver-nickel contact material supports reliable switching, while the standard RT II flux-proof construction suits automated PCB assembly processes.
With a 36 V DC sensitive coil, a 10 A rated contact current and a single-pole changeover configuration, the 40.31.7.036.0000 is suitable for switching control circuits, lighting, resistive loads and small single-phase motors. Its 3.5 mm contact pin pitch supports direct PCB installation or use with a compatible Finder 95 Series socket.

Reliable Switching for Control and Automation
Electromechanical relays such as the Finder 40.31 provide electrical isolation while allowing a low-power control circuit to switch a separate load. The changeover contact enables both normally open and normally closed switching functions, supporting flexible control arrangements within machinery and electronic systems.
The sensitive DC coil reduces control-side power demand, while the relay’s high coil-to-contact isolation supports dependable use where separation between control electronics and switched circuits is important. Compatible Finder 95 Series sockets can simplify installation, replacement and maintenance.
Typical Applications
- Industrial control and automation equipment.
- Electronic control boards and PCB assemblies.
- Machine control interfaces.
- Lighting and resistive load switching.
- Small single-phase motor control.
- Timers, control panels and interface modules.
