AR200 Laser Measurement Sensor

These laser measuring devices aim a Class 2 visible laser spot onto the target to accurately gauge its distance. Designed to withstand difficult industrial environments, the AR200 laser sensors are commonly used in automation, forest products, medical and high-tech industries.

Key Features

• Available displacement Range of 6mm, 12mm, 25mm, 50mm & 100mm
• Resolution of 0.03% across the entire measurement span
• Standard outputs of Analog, Limit Switch and Serial
• Sensors can be programmed using serial commands through a PC computer

The Acuity AR200 laser measurement sensors project a beam of visible laser light that creates a spot on a target surface. Reflected light from the surface is viewed from an angle by a CMOS line scan camera inside the AR200 sensor. The target’s distance is computed from the image pixel data. The AR200 can not be overloaded and measures accurately even when a mirror reflects the entire light beam back to the detector. This measurement principle is called triangulation. The signals are processed digitally and output on an RS232 line or are converted to an analog signal.

Although the AR200 laser measuring tools use metric nomenclature, the spans are in fact quarter, half, one, two and four inches for the -6, -12, -25, -50 and -100 models, respectively.

AR200 laser sensors are fast as well as accurate. The maximum sampling speed of the AR200 sensor is 1250 samples per second with a resolution of 0.03% of the measuring span. The AR200 is standard with many digital and analog outputs.

This Acuity model can only withstand temperatures to 50°C. Under some application circumstances, the AR200 laser measurement sensor can be used to measure to glass.

Standard RS-232 Full Duplex Serial Output

• All sensors come with an RS-232 serial output on a 6 foot, 9 pin cable that connects directly to PC style serial ports. Transmission rates are adjustable between 1200 to 230K baud. Serial output can be configured for one of several data formats. ASCII may be used for visual reading with a terminal device or emulation program, or a binary format can be used with application software. Using binary output, data transmission is 3 bytes / sample, 0 – 50K over full scale span and Hex FF terminated. ASCII output format is up to 11 bytes/sample.

Standard Current Loop Output

• A 4-20 milliamp current output is also standard. The zero and span for the current loop output may be set at any location. The span point (20 mA) may be made closer than the zero point if desired. The 4-20 mA output has a maximum voltage capability of 10 volts, and it is suggested that a 400 to 500 ohm load be used at the reading instrumentation for best accuracy.

Standard Voltage Output

• A 0-10V voltage output is standard on the AR200 laser measurement sensor. The zero and span points for the voltage output may be set at any location within the natural limits of the detector’s measuring range.

Standard Limit Switch Signals

• Limit switches will output a current of 100 mA if the measurement exceeds the limit switch. This current can be used to trigger external features such as secondary processes, audible and visible alarms or other PLC operations. Includes two NPN (sinking) and PNP (sourcing).

Procedure for connecting a 9-pin serial plug (DB9) to a AR200 laser sensor

• This document clearly illustrates the appropriate procedure for connecting a female DB9 connector to the bare wires of an AR200 laser sensor for those who do not have the optional Connectivity Kit.
