Prevent collisions while moving heavy loads with overhead bridge crane systems. These switches signal a crane to stop or slow when they detect that another crane or wall is too close. Mount the switch on your crane and the included reflector on the obstacle you want to avoid. The switch will bounce a light beam off the reflector to measure how far away it is—if it’s within the distance you’ve set, the switch triggers. These switches are also useful if you want to make sure a crane doesn’t move past a certain point. Turn the dials on the top to control the trigger distance and whether your crane stops or slows down. These switches can communicate with any crane that uses a variable frequency drive (VFD), soft starters, or contactor controls.

Mount the adhesive-backed reflector so the switch's light beam hits its center. Built to avoid signal interference from other switches, also known as crosstalk, these switches can be used next to each other without a problem. They use polarized light, so they filter out unwanted light beams and their beam stays focused on their reflector.

Rated IP67, these switches seal out dust and water, making them suitable for both indoor and outdoor applications.
