Why Choose the Finder 65.61.9.012.4000 Power Relay?
The Finder 65.61.9.012.4000 is a robust 20 A electromagnetic power relay designed for dependable electrical switching in industrial automation, machinery control and commercial equipment. Featuring a 12 V DC operating coil and a 1 normally open + 1 normally closed (1 NO + 1 NC) contact configuration, this relay enables low-voltage control circuits to operate separate higher-power electrical loads.
Part of the established Finder 65 Series power relay range, the 65.61.9.012.4000 combines reliable electromagnetic operation with silver tin oxide (AgSnO₂) contacts and direct printed circuit board (PCB) mounting. Its bifurcated solder terminals support integration into industrial electronic assemblies, while its complementary contact arrangement enables two switching functions from a single control coil.
With a 20 A contact rating at 250 V AC, 12 V DC coil and compact PCB-compatible construction, the Finder 65.61.9.012.4000 is suitable for industrial heating equipment, electrical control boards, machinery and OEM automation systems. It is particularly useful where one circuit must close while another opens in response to a common control signal.

Reliable High-Current Switching with Complementary Contacts
The Finder 65.61.9.012.4000 allows a 12 V DC control circuit to operate two complementary electrical switching functions. When the coil is energised, the normally open contact closes while the normally closed contact opens. Removing the coil supply returns both contacts to their original states, providing predictable control of connected circuits.
This 1 NO + 1 NC configuration is useful in equipment where one electrical function must be enabled as another is disabled. Typical examples include alternative operating modes, control signalling and coordinated switching functions within industrial machinery. The contacts are not a changeover contact, so circuit designs should account for their separate contact arrangement.
With its 20 A rated contacts, AgSnO₂ contact material and PCB mounting design, the relay provides a practical switching solution for industrial control boards and OEM equipment. Suitable coil drive circuitry, contact protection, electrical clearances and PCB conductor sizing should be provided according to the intended load and installation conditions.
Typical Applications
- Industrial automation and electrical control systems.
- Printed circuit board assemblies requiring power switching.
- 12 V DC controlled electrical load circuits.
- Machinery requiring complementary NO and NC switching functions.

- Commercial ovens and catering equipment.
- Boiler, burner and heating control assemblies.
- Industrial washing machines and commercial appliances.
- HVAC and ventilation control circuits.
- Electrical power management equipment.
- OEM electronic control boards and industrial machine building.
