Why Choose the Finder 50.12.9.060.5000 Forcibly Guided Safety Relay?
The Finder 50.12.9.060.5000 is a compact 8 A forcibly guided contact relay designed for safety-related switching, industrial automation and electrical control applications. Part of the Finder 50 Series, this PCB-mounted electromechanical relay features a 60 V DC coil, two changeover contacts and mechanically linked contact operation in accordance with EN 61810-3 Type B, previously EN 50205.
Unlike conventional switching relays, the Finder 50.12 incorporates forcibly guided contacts that provide a defined mechanical relationship between specified normally open and normally closed contacts. This construction supports contact-state monitoring and fault detection in appropriately designed safety-related control circuits. The silver-nickel contacts with gold plating (AgNi + Au) also support dependable low-level signal switching, making this variant particularly suitable for safety monitoring and control interfaces.
With an 8 A rated contact current, 60 V DC nominal coil, 700 mW coil consumption and 6 kV coil-to-contact impulse insulation, the Finder 50.12.9.060.5000 combines electrical switching capability with compact PCB integration. Its 29 × 12.4 × 25 mm housing, through-hole solder terminals and wide operating temperature range make it a practical choice for safety equipment manufacturers, automation engineers and electronic control system designers.

Reliable Safety Switching for Industrial Automation
The Finder 50.12.9.060.5000 provides mechanically linked contact operation for safety-related electrical control systems. When the 60 V DC coil is energised, the relay contacts change state, allowing connected circuits to perform switching and monitoring functions. Its EN 61810-3 Type B construction establishes a defined mechanical relationship between specified normally open and normally closed contacts, supporting the detection of certain contact faults through appropriately designed monitoring circuits.
The Finder 50 Series is particularly relevant to safety controller manufacturers, automation engineers and OEM equipment designers requiring compact PCB-mounted relays with defined contact guidance. The AgNi + Au contact material supports low-level signal switching, while reinforced insulation provides separation between the coil and contact circuits. For Type B relays, only the manufacturer-specified contact combinations should be treated as forcibly guided pairs. The relay is a component within a safety system rather than a complete safety controller, so the required safety performance must be established and validated at system level.
