43.41.7.012.0301 Finder Miniature PCB relay 1pole 10A DC 12V

Why Choose the Finder 43.41.7.012.0301 12 V DC 10 A Low-Profile PCB Relay?

The Finder 43.41.7.012.0301 is a compact low-profile electromechanical power relay from the Finder Series 43 range, designed for switching electrical circuits in industrial automation, electronic control equipment and machinery. Its miniature construction provides a practical solution for printed circuit board assemblies where installation space, reliable switching and electrical separation between control and load circuits are important.

Featuring a 12 V DC sensitive operating coil and a 10 A single-pole changeover contact, the Finder 43.41.7.012.0301 enables low-voltage electronic control circuits to switch appropriately rated electrical loads. Its single-pole double-throw (SPDT) arrangement provides normally open and normally closed connections, supporting auxiliary switching, signalling, interlocking and automated control functions.

The relay belongs to the Finder 43.41 low-profile PCB relay family, which features sensitive DC coils, reinforced coil-to-contact insulation and compact through-hole mounting. These characteristics make it suitable for control board manufacturers, industrial equipment designers and maintenance engineers requiring dependable electromechanical switching within space-constrained electronic assemblies.

Reliable Low-Voltage Control and Electrical Load Switching

The Finder 43.41.7.012.0301 operates through an electromagnetic coil that controls a mechanically linked changeover contact. Applying the nominal 12 V DC supply energises the coil and moves the common contact from its normally closed connection to its normally open connection. When the coil is de-energised, the contact returns to its original position.

This arrangement enables a low-voltage electronic controller to operate a separate electrical circuit while maintaining galvanic isolation between the coil and contact terminals. The Finder 43.41 relay family provides reinforced coil-to-contact insulation and compact PCB construction, making it useful in applications where control electronics and switched loads must be appropriately separated.

The relay's 250 mW sensitive coil is well suited to electronic control systems using an appropriately rated relay driver. Its 10 A changeover contact supports switching of resistive loads within the applicable ratings, while inductive and capacitive loads require additional consideration of inrush current, contact wear and suppression components. Correct PCB layout, protective circuitry and load selection help maintain dependable operation throughout the equipment's service life.
