41.31.9.012.0020 Finder Miniature PCB relay 1pole 12A DC 12V

Why Choose the Finder 41.31.9.012.0020 Low-Profile Power Relay?

The Finder 41.31.9.012.0020 is a compact 12 A electromechanical power relay designed for reliable electrical switching in industrial automation, electronic control systems and machinery. As part of the Finder 41 Series low-profile PCB relay range, it combines dependable switching performance with a slim housing that is particularly suitable for applications where installation height and circuit board space are limited.

Featuring a 12 V DC electromagnetic coil and a single-pole double-throw (SPDT) changeover contact, the relay allows a low-voltage control signal to switch a separate electrical circuit. Its normally open and normally closed contact arrangement provides flexibility for switching, signalling and auxiliary control functions in industrial and commercial equipment.

With a 12 A rated contact current, a 250 V AC rated contact voltage and a low-profile housing measuring approximately 15.7 mm in height, the Finder 41.31.9.012.0020 is well suited to PCB-based control assemblies, automation interfaces and electrical switching equipment. Its compact design and established Finder 41 Series construction support integration into OEM machinery and industrial electronic systems.

Reliable Low-Profile Switching for Industrial Automation

Electromechanical relays such as the Finder 41.31.9.012.0020 operate by energising an electromagnetic coil, which mechanically changes the position of the relay contacts. This enables a 12 V DC control circuit to switch a separate electrical load while maintaining galvanic isolation between the coil and contact circuits.

The Finder 41.31 relay series is particularly suitable for PCB-based equipment requiring compact dimensions and dependable electrical switching. Its single changeover contact supports normally open and normally closed control functions, while the low-profile housing helps simplify integration into electronic assemblies. Appropriate contact protection, PCB track sizing and adherence to the specified electrical ratings are important for reliable operation.
