The E-stop slave (Ø 16mm) is designed for the transmission of safety-related informations up to Safety Category 4 (EN 954-1) or Safety Integrity Level SIL3 (IEC 61508) respectively. These safe slaves fit onto several E-stop pushbuttons out of the Schlegel line. The E-stops are actuated by pushing and released by twisting the upper part. 'Disconnection (opening + latching) is clearly defined and effected by the fool-proof release function, which is achieved by power storaging and a snap-action mechanism.
