Bihl+Wiedemann offers a range of control and signal devices based on an innovative enclosure. The E-STOP switch module features a safety ASi input module and is available with 2-colour illumination – either depending on the actuator position or as specified by the controller.


The E-STOP is designed for extruded rail mount (40mm), but can also be individually attached using a mounting clip. The ASi connection is made conveniently using an M12 connection. Bihl+Wiedemann also offers various other control and signal devices in the same enclosure.
