QS-AW Collision Sensor

qsaw_nostem_corner_122008newThe QS-AW is a dynamically variable collision sensor that operates on an air pressure system.

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.

Factory-proven and engineered to withstand the harsh realities of these applications, QS-AW is the collision sensor specifically designed for arc welding, plasma cutting and laser cutting.

Key Benefits

  • Positive, variable air pressure to hold the QS-AW rigid during normal operation, resulting in more accurate welds and cuts
  • Permanent repeatability
  • Detects angular, rotational and compressive forces
  • Common mounting flange to work with a variety of torches
  • Flat plate or stem mount available
  • Built-in harsh environment shielding
