SF1-EX
Pin-type contact with spring return, EX-version
The pin-type contact SF1–EX is designed as a safety switch with positive contact and fulfills the demands for the use in explosion-endangered areas. It complies with the requirements of the norm series EN81-20 / EN81-50. The actuation is done by a pin with threaded stud. By the indirect actuation an especially large backlash (distance after contact opening) is allowed. The switch is used for the measuring of predetermined positions at moving parts (e.g. rope monitoring)
