Why Choose the Finder 40.31.7.028.0000 Miniature PCB Relay?
The Finder 40.31.7.028.0000 is a compact and dependable miniature electromechanical PCB relay designed for switching electrical loads in industrial automation, electronic equipment and control systems. As part of the established Finder Series 40, it combines a sensitive DC coil with a single changeover contact in a space-saving PCB and plug-in format.
This monostable relay provides one changeover contact rated at 10 A, allowing a control circuit to switch between normally closed and normally open paths. Its silver-nickel contact material provides reliable electrical performance, while reinforced insulation between the coil and contacts supports safe integration into industrial and electronic equipment.
With a sensitive 28 V DC coil, a coil power consumption of 0.5 W and compact dimensions of 29 × 12.4 × 25 mm, the Finder 40.31.7.028.0000 is well suited to densely populated control assemblies. It can be mounted directly onto a printed circuit board or installed through a compatible Finder Series 95 socket.
