The STS4 safety switch in conjunction with the STS4/B actuating element functions according to the identification principle with a six-digit safety code that is only issued once.

As certified by the German Trade Association for Precision and Electrical Engineering, the STS4 safety switch in conjunction with the STS4/B actuating element functions according to the identification principle with a six-digit safety code that is only issued once. This non-contact system is extremely tamper-proof. The switch complies with Control Category 4 as defined by EN954-1, with its response range it is insensitive to mechanical tolerances and is therefore suited for monitoring safety areas in semi-automated industrial plants that are separated by safety walls and doors.

Should the application require a re-alignment of the sensor (active surface), the switch can be quickly and easily modified on site.
