Laser Scanners - Allen Bradley Guardmaster™
The Allen Bradley Guardmaster® SafeZone™ Safety Laser Scanners from Rockwell Automation are Type 3 opto-electronic devices that protect personnel or equipment by detecting them in its sensing field. Operating on the 'time of flight' principle, the scanners emit pulses of eye-safe infrared laser light over a 190- or 270-degree arc, then receive and process the light reflected off of intrusions in the sensing field to determine the position and distance to the object. When an object is detected, the scanners send a stop signal to the protected machine.
