40.61.7.018.1000 Finder Miniature PCB relay 1pole 16A DC 18V

Why Choose the Finder 40.61.7.018.1000 Miniature Power Relay?

The Finder 40.61.7.018.1000 is a compact electromechanical miniature power relay from the Finder Series 40, designed for reliable electrical switching in industrial automation, electronic control equipment and machinery applications. Its space-efficient construction makes it particularly suitable for printed circuit board assemblies where dependable switching and compact component dimensions are important.

Featuring an 18 V DC nominal coil voltage, a single changeover contact (1 CO) and a 16 A nominal contact rating, this relay provides an effective interface between low-voltage control electronics and compatible electrical loads. Its electromagnetic switching mechanism allows a control signal to operate an independent electrical circuit while maintaining galvanic separation between the coil and contacts.

The Finder 40.61.7.018.1000 belongs to Finder's established 40.61 miniature power relay family. Its PCB mounting arrangement, compact housing and versatile changeover contact functionality make it suitable for OEM equipment manufacturers, automation engineers and electronic control system designers requiring reliable auxiliary switching.

Key Advantages

• 18 V DC nominal coil voltage for compatible low-voltage DC control circuits.

Reliable 18 V DC Relay Switching for Electronic Control Systems

The Finder 40.61.7.018.1000 operates through an electromagnetic coil that changes the position of its single changeover contact. When the 18 V DC coil is energised, the common contact transfers from the normally closed terminal to the normally open terminal. When the coil supply is removed, the contact returns to its original position, enabling straightforward control of compatible electrical circuits.

The Finder Series 40 is developed for applications requiring compact construction, dependable switching and efficient integration into electronic equipment. The 40.61 relay type offers a 16 A nominal contact rating, making it suitable for a range of auxiliary power-switching functions. The actual permissible switching load depends on voltage, load category, inrush current, switching frequency and operating conditions, so the applicable manufacturer ratings should be observed during equipment design.
