Finder 50.12.9.006.5000 – 50 Series Relays with forcibly guided contacts

Why Choose the Finder 50.12.9.006.5000 Force-Guided Safety Relay?

The Finder 50.12.9.006.5000 is a compact 8 A force-guided PCB relay with gold-plated contacts, designed for industrial safety monitoring, low-level signal switching and electronic control applications. Part of the Finder 50 Series, this specialist electromechanical relay features mechanically linked contacts conforming to EN 61810-3 Type B, previously EN 50205, supporting reliable contact-state monitoring in appropriately designed safety-related circuits.

Featuring a 6 V DC nominal operating coil, two changeover contacts (2 CO / DPDT) and silver nickel contacts with gold plating (AgNi + Au), the Finder 50.12.9.006.5000 is particularly suitable for applications requiring dependable switching of low-level electrical signals. The gold-plated contact surfaces help maintain reliable electrical connections at relatively low voltages and currents, while the relay retains an 8 A rated contact current for suitable higher-power switching applications.

The .5000 variant is specifically designed with gold-plated contacts for enhanced low-level switching capability, distinguishing it from the standard AgNi .1000 version. With 6 kV coil-to-contact impulse withstand voltage, 8 mm insulation separation, RT II flux-proof protection and compact through-hole PCB mounting, this relay provides a versatile switching component for industrial control electronics, safety monitoring modules and OEM equipment.

Gold-Plated Force-Guided Contacts for Sensitive Safety Monitoring

The key advantage of the Finder 50.12.9.006.5000 is its combination of force-guided contact technology and gold-plated contact surfaces. The force-guided mechanism mechanically links specified normally open and normally closed contacts so that certain contact welding faults can be detected through an appropriately designed monitoring circuit. This behaviour supports the implementation of safety-related control functions where reliable feedback is required.

The AgNi + Au contact material makes the .5000 variant especially suitable for switching low-level signals. Gold plating helps maintain contact performance where low voltages and currents might otherwise be affected by surface films or increased contact resistance. The manufacturer's 50 mW minimum switching load distinguishes this variant from the standard silver nickel version, making it useful for sensitive electronic control and feedback circuits.

The relay provides two changeover contacts, but its EN 61810-3 Type B classification does not mean that every contact combination is force-guided. For compliant monitoring, Finder specifies the appropriate pairing of one normally open and one normally closed contact, such as terminals 11–14 with 21–22 or 11–12 with 21–24. Designers must follow the manufacturer's contact diagram and assess the complete safety function rather than relying on the relay alone to establish a safety performance level.
