40.61.7.012.1021 Finder Miniature PCB relay 1pole 16A DC 12V

Why Choose the Finder 40.61.7.012.1021 Miniature Power Relay?

The Finder 40.61.7.012.1021 is a compact electromechanical miniature power relay from the Finder Series 40, designed for dependable electrical switching in industrial automation, electronic control equipment and machinery applications. Its space-efficient construction makes it suitable for printed circuit board assemblies requiring reliable control of electrical loads.

Featuring a 12 V DC nominal coil voltage, a single changeover contact (1 CO) and a 16 A nominal contact rating, this relay provides a practical interface between low-voltage control electronics and compatible electrical circuits. Its electromechanical switching mechanism allows a control signal to operate a separate load circuit while providing galvanic separation between the coil and contacts.

The Finder 40.61.7.012.1021 belongs to Finder's established miniature relay range and is suitable for integration into electronic control boards, OEM equipment and compatible relay socket assemblies. Its changeover contact arrangement offers flexible switching for automation, auxiliary control and electrical signalling applications.

Key Advantages

• 12 V DC nominal coil suitable for compatible low-voltage control systems.

Reliable 12 V DC Relay Switching for Electronic Control Systems

The Finder 40.61.7.012.1021 operates through an electromagnetic coil that changes the position of its single changeover contact. When the 12 V DC coil is energised, the common contact transfers from the normally closed terminal to the normally open terminal. Removing the coil supply allows the contact to return to its original position, providing straightforward control of compatible electrical circuits.

Its 16 A nominal contact rating makes the Finder 40.61 relay type suitable for a range of auxiliary power-switching applications. Actual permissible switching loads depend on voltage, load category, inrush current, operating conditions and the manufacturer's applicable ratings. The compact PCB format is particularly useful for electronic equipment manufacturers seeking dependable switching without the space requirements of larger industrial relays.
