Our most sensitive limit switches, these switches actuate with the slightest push for a high degree of accuracy. They’re often used for determining manufacturing tolerances and detecting minute expansions and contractions. When an object pushes into the plunger actuator, it sends a signal to open or close a circuit. Install them in a standard panel cutout.

Sealed actuators prevent these switches from jamming, even when exposed to oil, sand, mud, or ice. They send a signal to your circuit when an object hits the actuator—for instance, a box on a conveyor runs into the switch, stopping the conveyor. They open and close circuits as fast as snap-acting switches, but they have a bigger actuator for large objects. To actuate, they require a push, similar to a button. Rated IP68, they’re protected against dust and temporary submersion.

Secure these switches into panel cutouts using mounting nuts. They have a slim body so they can also be stacked together or fit into tight spaces. These switches have the rapid-closing action of a snap-acting switch, but have a larger actuator for large objects. When an object in motion comes into contact with the actuator, it sends a signal to open or close a circuit. They’re often used on conveyor systems and elevators. All are rated IP67 for protection from temporary submersion. They have a 4-pole micro M12 plug that connects to cables with a socket (sold separately), allowing you to quickly connect and disconnect the switch.

Rated IP67, these switches have an enclosure that shields their interior during temporary submersion. They open and close circuits in a snap—their quick actuation limits arcing and keeps contacts from sticking. These switches are often used to indicate an open appliance or enclosure door. You can also use them inside limit, pressure, and temperature switches.
