Reliable Safety Switching for Industrial Machinery

Safety relays with forcibly guided contacts are essential components in many industrial safety-related control systems. Their mechanically linked normally open and normally closed contacts are designed so that opposing contact types cannot simultaneously remain closed under specified fault conditions. This enables external monitoring circuits to detect failures such as welded contacts and supports diagnostic functions in appropriately designed machinery safety systems.

The Finder 7S.16.8.230.5420 provides a 4 NO + 2 NC contact arrangement, making it suitable for applications requiring multiple switching paths and dedicated feedback contacts. Its six-pole construction allows machine builders to integrate switching and monitoring functions within a single compact relay assembly.

The relay incorporates Class A forcibly guided contacts conforming to EN 61810-3. The Finder 7S Series is designed for use in functional safety applications, with series-level evaluation supporting integration into systems designed for up to SIL 2 or Performance Level d (PL d), subject to the complete system architecture, diagnostic coverage and safety assessment.

Its 230 V AC coil, durable contact construction and compact DIN rail housing make it particularly useful for industrial electrical panels, machinery control circuits and safety interface assemblies. The integrated LED indicator provides visual confirmation of coil energisation, while spring-loaded terminals simplify wiring and servicing.
