Part Numbers
The Z/T336 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 six standard actuators … rounded plunger, roller plunger, roller rocking lever, rod rocking lever, adjustable roller rocking lever and one-way roller 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.
Units are available with a choice of slow-action or snap-action contacts.
Their rugged fiberglass-reinforced thermoplastic housing and IP67 rating make them ideal alternatives to conventional limit switches.
