Washdown Limit Switches








Rated NEMA 3S and IP69K, these switches can handle washdowns with high pressures and temperatures. They’re also protected from oil/coolant spraying, precipitation, and temporary submersion. When an object in motion contacts the actuator, it sends a signal to open or close a circuit. These switches have the rapid-closing action of a snap-acting switch, but with a larger actuator. This makes them a good choice for use with large objects—for instance, a box on a conveyor runs into the switch, stopping the conveyor.
Switches with a plunger actuator require a push to actuate, similar to a button.
Switches with a roller plunger actuator trigger just like a plunger actuator but reduce friction during actuation thanks to their roller. This limits wear and tear on the switch.
Switches with a roller lever actuator combine the larger actuation area of a standard lever with a smooth gliding roller actuator. They minimize friction to limit wear and tear on your switch.
Switches with a rod actuator use a rod extending out of the body to actuate, so they’ll activate even if an object is far away.
Switches with a wobble stick actuator have an arm that rotates 360°, so you don’t need to align it in a specific direction. Since the actuator is flexible, it won’t snap if pushed backward. That makes these switches a great choice for systems that get jammed often.
Styles D, E, and F let you adjust the actuator’s height to align it with your target.
