AR500 Laser Position Sensors

AR500 Laser Position Sensors use triangulation measurement principles to gauge distances to targets with great accuracy and speed. Fitting in the palm of the hand, the unit’s size is ideal for builders of compact machines and systems. Available with many different diode options, the AR500 can measure to nearly any kind of target: dark, shiny, bright, opaque, translucent, etc.

A diode within the sensor, projects a beam of visible (or optionally, infrared) laser light that creates a spot on a target surface. Reflected light from the surface is viewed from an angle by a digital CMOS line scan camera inside the AR500 sensor. The target’s displacement is computed from the image pixel data. The result is transmitted via serial or analog interfaces to a computer, display, PC or PLC.
