Robotic Collision Sensors provide crash protection and increased safety by mechanically detecting when the robot arm* has encountered an obstruction, absorbing the crash energy, and quickly signaling the robot to stop – thus preventing costly damage to equipment and tooling.
RAD’s Spring-Assist Ultimatic™ Pneumatic Collision Sensor minimizes the potential for costly damage to the robot arm or tooling in the event of a crash and maximizes uptime by automatically returning to within 0.0005″ (0.013mm) of its starting position once it has been separated from the source of the crash.
NOTE: RAD Spring-Assist Ultimatic™ Collision Sensors effectively replace the discontinued EOA MultiClutch Breakaway Safety Devices. For more information, click here.
The Spring-Assist Ultimatic™ Collision Sensor is RAD’s patented mechanical collision sensor that:
RAD’s Spring-Assist Ultimatic™ Collision Sensor works by establishing the minimal points of contact required to restrain all degrees of freedom (movement) in normal operation. When a robotic crash occurs, external forces upset this balance thereby allowing angular, rotational or compressive compliance. This motion opens a normally closed switch and sends a signal to your robot’s E-stop or controller.
Note: The Spring-Assist Ultimatic™ Collision Sensor can be used as a compliance (alignment) device rather than a collision sensor by simply mounting the unit without wiring it to the robot. Please see the Compliance Device section for more end-effector compliance options.
