The Acuity AR700 laser distance sensor employs triangulation measurement principles whereby it 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 AR700 sensor. The target’s displacement is computed from the image pixel data.

The AccuRange 700 series includes thirteen measurement ranges from 1/8th inch to 50 inches (3.2 mm to 1.3 m). The linearity specification is among the best in the industry, +/-0.03% of the sensor's measuring span.

This distance sensor, similar to the AR200 is standard with a variety of serial and analog outputs. On either RS232 or RS422, data formats include ASCII English, metric, native and two binary outputs. The sensor can output error codes for: Target too near, Target too far, Target not seen and Laser off. Analog outputs include a 4-20 mA current loop, 0-10V outputs and two NPN sinking limit switches. All parameters and settings are selectable from pushbuttons on the sensor or through PC serial commands.

Do you already own an AR700 and are unsure which model it is? You can cross-reference the stamped part number with the offical Acuity Model Number by reviewing our product offering list.
