40.31.9.110.5300 Finder Miniature PCB relay 1pole 10A DC 110V
Finder 40.31.9.110.5300 is a flux-proof miniature power relay with a 110 V DC coil, one normally open 12 A contact, AgNi + Au contact material and 5.2 mm plug-in pins.
Why Choose the Finder 40.31.9.110.5300 Miniature Power Relay?
The Finder 40.31.9.110.5300 is a compact and dependable miniature PCB and plug-in electromechanical power relay designed for switching electrical loads in electronic equipment and industrial control systems. As part of the Finder Series 40, it combines a normally open contact, standard DC coil and plug-in-compatible terminals in a space-efficient enclosure.
This relay provides reinforced insulation between its coil and contact circuit, high mechanical endurance and flux-proof RT II environmental protection. Its gold-plated silver-nickel contact supports reliable switching in control and signalling circuits, while the plug-in format allows direct PCB installation or use with a compatible Finder Series 95 socket.
With a 110 V DC coil, one normally open contact rated at 12 A when PCB-mounted and 10 A when socket-mounted, the 40.31.9.110.5300 is suitable for automation equipment, control assemblies and electrical panels. Its 5.2 mm terminal pins provide flexible PCB or socket mounting.
