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.
