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.

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 IP67 for protection from washdowns and temporary submersion.
