Product Code: SF1-AEL-EX
Product Description
Technical Information:
The SF1-EX Pin-Type Contact is designed as a safety switch with positive contact designed to meet the demands for use in potentially explosion-endangered areas. It complies with the requirements of the EN81-20 / EN81-50 safety standard regulations. It is actuated via a pin with a threaded pin (size M6). The indirect actuation enables a particularly large overrun (path after contact opening). The switch required to determine predetermined positions for moving components (e.g. for rope monitoring).
