The Uni-Coupler™ Collision Sensor is RAD’s patented, spring-loaded, mechanical collision sensor that:

• Stops the robot* in the event of a crash to minimize costly damage to the robot and/or tooling. RAD’s collision sensor provides protection even if the robot itself is not moving.
• Absorbs the crash energy by allowing up to 15º of deflection following a collision.
• Automatically resets to within ± 0.002″ (0.051mm) to maximize uptime and eliminate the need for human intervention.
• Allows up to 0.040″ (1.02mm) “give” in the coupling before the load sensing mechanism is activated (in compliant models) to avoid nuisance tripping.

Operating Principle
RAD’s Uni-Coupler™ Collision Sensor is a spring-loaded mechanical device that signals your robot’s E-stop or controller when the tooling encounters an obstruction. The lateral or vertical force applied during a collision opens a normally closed switch that sends the “stop” signal.

Note: The Uni-Coupler™ Collision Sensor can be used as a compliance device by installing the unit without connecting the sensor switch.

* can also be used on linear actuators, pick & place machines, and other automated equipment.
