Why Choose the Finder 40.61.8.024.0000 Miniature Power Relay?
The Finder 40.61.8.024.0000 is a compact and dependable miniature electromechanical power relay designed for switching higher-current electrical loads in industrial controls, building automation and electronic equipment. As part of the established Finder 40.61 Series, it combines a changeover contact with a 24 V AC coil and flexible PCB or socket installation.
This monostable, non-latching relay provides a 1 CO / SPDT contact configuration and uses silver-cadmium-oxide contacts for reliable load switching. Its RT II flux-proof enclosure helps protect the internal mechanism during PCB assembly, while the compact housing enables efficient use of space inside control equipment.
With a 24 V AC coil and a 16 A resistive contact rating at 250 V AC, the Finder 40.61.8.024.0000 is suitable for switching lighting, heating, motors, pumps and other demanding electrical loads. Its 5 mm contact pin pitch supports direct PCB mounting or installation in a compatible Finder 95 Series relay socket.

Reliable Power Switching for Electrical Control Systems
Electromechanical relays such as the Finder 40.61 provide galvanic isolation between the energising circuit and the switched load. Applying 24 V AC to the coil transfers the changeover contact, enabling a control circuit to switch higher-current electrical equipment safely and reliably.
The Finder 40.61 Series is designed for integration into printed circuit boards and industrial control assemblies. Its compact housing, 16 A contact capacity and compatibility with Finder 95 Series sockets make this model suitable for both equipment manufacture and maintainable panel installations.
Typical Applications
- Industrial control panels and automation equipment.
- Building automation and lighting controls.
- Heating and temperature-control systems.
- Pumps, fans and small motor controls.
- Electrical appliances and power interfaces.
- Printed circuit boards and socket-mounted control assemblies.
