QS

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
