Finder 34.51.7.012.4010 Miniature PCB Power Relay 12 V DC, 6 A, 1 CO

In industrial control panels and automation systems, switching a load reliably with a compact component is a constant challenge. The Finder 34.51.7.012.4010 miniature PCB power relay solves this by providing a single changeover contact rated for 6 A, driven by a 12 V DC coil that consumes only 170 mW. Its reinforced insulation and 5000 V AC dielectric strength between coil and contacts ensure safe separation between control and load circuits.

Who is it for

This relay is intended for design engineers and panel builders who need a space-saving, through-hole PCB relay for signal switching, interfacing, or driving small loads in industrial electronics, HVAC systems, or building automation.

Tips

For reliable operation, ensure the PCB layout provides adequate clearance and creepage distances as required by the application's safety standards. When driving the coil from a transistor or driver IC, consider the coil's back-EMF and use a freewheeling diode to protect the driver.
