Collision Sensors

QS

The QS is a dynamically variable collision sensor that operates on an air pressure system – and provides excellent protection in machine load/unload robotics applications.

A regulated air supply provides positive, variable pressure to hold the collision sensor rigid during normal operation. At impact, the air chamber seal is opened, immediately signaling the system controller.

Advantages

Dynamically variable trip points
Permanent repeatability
Detects angular, rotational and compressive forces
