Schmersal's product portfolio includes more than 25,000 products for safety door monitoring, including solenoid interlocks, safety sensors and safety switches with separate actuators and devices for rotating protective equipment. The portfolio also includes opto-electronic safety equipment including safety light barriers, light grids and curtains to help guard hazard spots on machines and other hazardous areas. In addition, Schmersal also develops and manufactures systems for safe signal processing, including safety relay modules, safety modules and programmable modular safety controllers that can be linked to safety door switches, emergency stop switches and light grids or other electronic and mechanical safety switchgear devices. When it comes to explosion protection, Schmersal offers a range of devices for ex zones.
Safety relay modules and safety controllers for various safety technology applications (e.g. for emergency stop and guard door monitoring) as well as centralised programmable safety controllers and decentralised field bus systems, e.g. a modular concept for safety function control on small machines.
Non-contact safety switches operate without the use of conductive contacts to complete or break the circuit. Instead, they utilise a magnet, transponder or inductor to detect when the power to a machine needs to be cut. They can be used in machine-guarding applications to prevent injury to personnel in hazardous areas.
