Bumper Switches
Sensitive along their entire length, these switches are often used to signal when an overhead door closes or an item reaches the end of a conveyor. The sealed housing protects against exposure to weather.
Optional mounting channels (sold separately) secure switches to walls or conveyors.

Safety Bumper Switches
Prevent automatic doors from closing on a person or an object—these switches immediately turn machinery off when actuated with minimal force. Combine with a controller (sold separately) to create a self-monitoring system that also shuts off machinery when a fault is detected. They’re sensitive along their entire length and often used to signal when an overhead door closes or when an item reaches the end of a conveyor. The attached mounting channel can be mounted to a door or flat surface. Punch or drill holes into the channel to match an existing hole pattern or create a new mounting pattern. Switches are rated IP65 for protection from washdowns.

Wear-Resistant Bumper Switches
Made of polycarbonate, these switches won't wear down even as objects constantly bump into them, unlike rubber bumper switches. They come in a sealed housing, so you don't need a mounting channel. Sensitive along their entire length, they're often used to signal when they've been hit by a cart or other rolling equipment.

High-Force Safety Bumper Switches
Minimize false triggers—these switches require 10 lbs. of actuation force in order to shut off machinery immediately. Combine with a controller (sold separately) to create a self-monitoring system that also shuts off machinery when a fault is detected. They’re sensitive along their entire length and often used to signal when an overhead door closes or when an item reaches the end of a conveyor. The attached mounting channel can be mounted to a door or flat surface. Punch or drill holes into the channel to match an existing hole pattern or create a new mounting pattern. Switches are rated IP65 for protection from washdowns.
