Bihl+Wiedemann offers a range of control and signaling devices based on innovative housings. Standard products are available from stock. Upon request, a housing with one or two openings can also be equipped with any of the common control and signaling devices (lights, buttons, illuminated buttons, key switches, selector switches, E-Stops, etc.) The control and signaling devices are designed to mount onto 40mm extruded rail, but can also be attached using a mounting clip. The AS-i connection is made by using a convenient M12 connection. For safety applications we also offer a safe AS-i E-STOP switch module.
