Safety Relays

A safety relay is a critical electromechanical switching component used in safety-related control systems to ensure reliable operation of machinery and protect human lives. It works by monitoring safety inputs (like emergency stop buttons or light curtains) and ensures that proper safety actions are taken—such as stopping a motor or disconnecting power—when a fault is detected.

Unlike standard relays, safety relays are designed with special internal structures such as forcibly guided contacts, which ensure reliable detection of contact welding or failure—an essential feature in safety-critical applications.
