AR500 Laser Position Sensor

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.

Key Features

• Models ranging from 5 to 1000 mm of measurement range
• Linearity of 15% of Span at 500 Hz, to white target (85% diffuse reflectance)
• Standard sampling rate up to 9.4KHz
• Resolution of 0.01% of Span across the entire measurement span
• Standard outputs of Analog, Trigger and Serial
• Sensors can be programmed using serial commands through a PC computer
• AR500 Laser Position Sensors are available with optional blue laser diodes

HOW IT WORKS

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.

MANY RANGES, ONE CASE SIZE

With nine different available measurement spans, the AR500 series measures from 5 to 1000 mm of displacement. Unlike the AR700 laser displacement sensors, all of these ranges use the identical, compact case size. Fitting in the palm of your hand, the AR500 rivals the tiniest of triangulation sensors available for industrial applications. The small enclosure means a very “sharp” beam path, permitting measurement down narrow tubes and small windows.

RED, BLUE OR IR LASERS

The AR500 comes standard with RED visible laser diodes. The shorter-range models require lower-powers and meet Class 2 laser requirements. The longer-range models are Class 3R and can be optionally ordered with high-power diodes at Class 3B for measuring black surfaces. As an option, all sensors can be ordered with different powers of 405 nm BLUE laser light. These models are idea for measuring to glowing-hot targets, polished metals and glass.
