Why Choose the Finder 65.31.9.012.4000 Industrial Power Relay?
The Finder 65.31.9.012.4000 is a robust 20 A industrial electromechanical power relay designed for dependable electrical switching in industrial automation, machinery control, electrical distribution and equipment management applications. As part of the Finder 65 Series, this relay combines a low-voltage DC operating coil with separate normally open and normally closed power contacts, providing flexible control of electrical circuits.
Featuring a 12 V DC operating coil and a 1 NO + 1 NC (SPST-NO + SPST-NC) contact arrangement, the Finder 65.31.9.012.4000 allows two separate switching functions to operate from a single coil. Its silver tin oxide (AgSnO2) contact material offers a cadmium-free contact solution, while the electromechanical construction provides predictable switching behaviour for industrial control systems.
With a 20 A rated contact current, 250 V AC rated contact voltage and 5,000 VA AC-1 resistive switching capacity, this relay is suitable for appropriately rated industrial electrical loads. Its rear flange mounting and Faston 250 quick-connect terminals provide a practical installation arrangement for electrical control panels, OEM machinery and industrial equipment.

Reliable Power Switching for Industrial Automation
The Finder 65.31.9.012.4000 provides a practical interface between a 12 V DC control circuit and electrical equipment requiring higher-current switching. When the relay coil is energised, its normally open contact closes while its normally closed contact opens. When the coil is de-energised, both contacts return to their original positions. This complementary switching arrangement supports control logic, equipment interlocking and electrical load management.
The Finder 65 Series is designed for industrial applications where robust construction and dependable electromechanical operation are important. The 65.31.9.012.4000 combines a 20 A contact rating with silver tin oxide contacts and a 5,000 VA AC-1 resistive switching capacity, making it suitable for appropriately rated industrial heating equipment, electrical control assemblies and machinery applications.
Its rear flange mounting and Faston 250 terminals allow the relay to be incorporated into industrial control panels and equipment assemblies. When selecting the relay for motors, inductive loads or equipment with high starting currents, the applicable load-specific switching rating, expected operating frequency and electrical protection requirements should be checked against the manufacturer's technical documentation.
Typical Applications
- Industrial machinery and electrical automation control panels.
- 12 V DC control systems requiring higher-current load switching.
- Electrical distribution cabinets and auxiliary control assemblies.
- Industrial heating and temperature control equipment.
- Complementary normally open and normally closed switching circuits.
