SCHMERSAL specializes in the design and manufacture of industrial switches, machine safety products, position sensors and related control accessories. You can also take a look at the Schmersal Product Overview. The Z332 Series limit switches are designed for use with movable machine guards/access gates which must be closed for operator safety … and for any other presence/position sensing application normally addressed with conventional limit switches. Their positive-opening NC contacts provide a higher level of safety and/or reliability than conventional spring-driven switches whose contacts can weld or stick shut. Each is available with a choice of five standard actuators … rounded plunger, roller plunger, roller rocking lever, rod rocking lever and adjustable roller rocking lever … mountable in any one of four 90° positions. All rocking levers are positively-locked to the shaft, and are adjustable throughout 360° in 10° increments. Their rugged metal housing and IP65 rating make them ideal alternatives to conventional limit switches. The Z332 Series may be used in any presence/position sensing application normally addressed with conventional limit switches. Featuring positive-break NC contacts, they are approved for use in safety systems. For safety applications the switch must be mounted such that the actuating element of the machine displaces the switch actuator far enough to exceed the positive-break point. |
