AR200 Laser Displacement Sensor
The AR200 group of laser measurement sensors is Acuity's most compact series of triangulating laser displacement sensors. Four models cover metric measurement ranges from six to hundred millimeters.

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

The AR200-6, AR200-12, AR200-25, AR200-50 and AR200-100 have ranges in millimeters that match their model number. All models boast a 0.03% resolution across their entire measurement span.

All models are standard with Analog, Limit Switch and Serial outputs. The AR200 sensor is the only sensor of its kind to feature pushbutton selection of these output signals. Additionally, these laser sensors can be programmed using serial commands through a PC computer.

Overview of data outputs:-
The AR200 laser measurement sensor is a digital device that includes several digital outputs. These outputs inlcude RS-232. After an on-board digital to analog conversion, the sensor also offers a 4-20 mA signal, a 0-10 V signal and two limit switches. Operators select the output by activating pushbuttons on the sensor's interface panel or through software instructions.

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 s ested 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).
