The AR100  laser position sensors are ultra compact devices for dimensional measurement/ The unit uses laser triangulation principles to accurately measure at high speeds. The same mini enclosure houses models with ranges from 20 to 500 mm. Sensor options include blue laser diodes

Principles of operation

The AR100 is a triangulation sensor that measures distance by projecting a beam of laser light that creates a spot on a target surface. Reflected light from the surface is viewed from an angle by a CMOS detector array inside the AR100 sensor. The target’s distance is calculated from the image pixel data using the sensor’s microprocessor. The distance is transmitted through serial communications, analog outputs are available. A variety of models are specified, each to allow a different measurement range and standoff.
