Why Choose the Finder 40.51.8.230.0000 Miniature Relay?
The Finder 40.51.8.230.0000 is a compact and dependable miniature electromechanical power relay designed for switching electrical loads in industrial controls, building automation and equipment interfaces. As part of the established Finder 40 Series, it combines a single changeover contact with flexible PCB or socket installation.
This monostable, non-latching relay provides a 1 CO / SPDT contact configuration and uses durable silver-nickel contacts. Its flux-proof RT II construction helps protect the internal switching mechanism during PCB assembly, while the compact housing suits applications where panel or board space is limited.
With a 230 V AC coil and a 10 A rated contact current, the Finder 40.51.8.230.0000 provides reliable isolation and load switching for control panels, machinery and automation equipment. Its 5-pin layout and 5 mm terminal pitch support direct PCB mounting or installation in a compatible Finder 95 Series relay socket.

Reliable Switching for Electrical Control Systems
Electromechanical relays such as the Finder 40.51 provide galvanic isolation between the energising circuit and the switched load. Applying the specified voltage to the coil operates the changeover contact, enabling a control circuit to switch lighting, heating, motors, solenoids and other electrical equipment.
The Finder 40 Series is designed for dependable integration into printed circuit boards and industrial control assemblies. Its compact format, robust AgNi contacts and compatibility with Finder 95 Series sockets make this relay suitable for both equipment manufacture and maintainable panel installations.
Typical Applications
- Industrial control panels and automation equipment.
- Building automation and lighting controls.
- Heating, ventilation and temperature-control systems.
- Machine control and electrical interlocking circuits.
- Pumps, fans, solenoids and small motor controls.
- Printed circuit boards and equipment interfaces.
