SF1-EX - Pin-Type Contact with Spring Return

The pin-type contact SF 1 - EX is designed as a safety switch with positive contact and complies with the demands of the European Regulations EN 81-1 and EN 81-2, issue February, 1999. Furthermore, it fulfills the demands for the use in explosion-endangered areas. The actuation is done by a pin with threaded stud. By the indirect actuation an especially large following (distance after contact opening) is allowed. The switch is used for the measuring of predetermined positions at moving components (e.g. rope monitoring). Other pin-type contacts from the booklet "switches" are available as an ATEX-version as well. The type treated here serves only as an example.
