43.41.7.012.0300 Finder Miniature PCB relay 1pole 10A DC 12V

Why Choose the Finder 43.41.7.012.0300 12 V DC 10 A Low-Profile PCB Relay?

The Finder 43.41.7.012.0300 is a compact and dependable low-profile electromechanical PCB relay designed for electrical switching in electronic control equipment, industrial automation and machinery applications. As part of the established Finder Series 43 miniature relay range, it combines sensitive DC coil operation with reliable contact switching in a space-saving housing suitable for printed circuit board integration.

Featuring a 12 V DC sensitive operating coil and a 10 A single-pole changeover contact, the Finder 43.41.7.012.0300 enables low-voltage control circuits to operate separate electrical loads. Its single-pole double-throw (SPDT) configuration provides normally open and normally closed switching connections, making it suitable for control logic, signalling, auxiliary switching and equipment interfacing.

The relay features a low-profile PCB mounting design and an electromagnetic switching mechanism that provides galvanic separation between the control coil and contact circuit. Its compact construction makes it suitable for electronic control boards, automation modules and OEM equipment where dependable switching and efficient use of installation space are essential.

Reliable Low-Profile Switching for Electronic Control Systems

Electromechanical relays such as the Finder 43.41.7.012.0300 use an electromagnetic coil to operate a separate electrical switching circuit. When the 12 V DC coil is energised, the internal armature transfers the common contact from the normally closed terminal to the normally open terminal. When the coil supply is removed, the relay returns to its normal contact position.

The Finder Series 43 is developed for electronic equipment requiring compact construction, sensitive DC coil operation and dependable switching. The 43.41 configuration provides a single 10 A changeover contact, allowing low-voltage electronic controls to operate appropriately rated electrical loads without a direct conductive connection between the coil and switched contact circuits.

The relay's low-profile housing supports installation in compact printed circuit board assemblies, making it useful for electronic control modules, industrial automation equipment and OEM machinery. When designing a control circuit, engineers should ensure that the coil-driving output can supply the required operating current and that contact ratings are appropriate for the connected load. Inductive and capacitive loads may require additional suppression or protective components to maintain reliable switching performance.
