Safety sensor on Reed contact basis with built-in relay

Safety sensor 171…


with built-in relay

 

The safety sensor with built-in relay 171K... monitors guard doors and protective covers on machines and systems to protect personnel. The combination of safety sensor and safety control electronics in one housing, saves a great deal of space since no additional safety control device is necessary in the switch cabinet. This is a space-saving and cost effective solution, particularly for small machines and systems.
