Fast Speed, Long Range, Compact Design
Acuity’s AR2700 high-speed long range sensor uses time-of-flight measurement principles to measure long distances at short measurement intervals to provide precise accuracy at high sampling rates.
The ultra-compact AR2700 laser sensor can measure distances from 0.2 m (8 in) to 70 m (230 ft) to natural targets of low reflectance (10%). The accuracy is generally specified with an absolute linearity of +/- 2.36 inches (60 mm) and a repeatability of +/- 0.98 inches (25 mm). The AR2700 linearity will vary depending on sample averaging, temperature, and surface reflectivity of the target surface. The sensor has maximum sampling rate of 40,000 samples per second and measurements can be triggered using an input signal wire or a serial command at rates up to 30Khz.
For very distant measurements, you can use retroreflective target material (such as 3M Scotch lite 3000X) to increase the maximum range to 270 meters (885 feet).
Class 1, Eye-safe Laser
The AR2700 laser sensor operates with a Class 1, eye-safe, 905 nm infrared diode. The tiny laser spot has a beam divergence of 2 milliradians. The Class 1 laser is able to be used in most environments and is FAA approved to be operated in outdoor applications near airports.
Versatile, High-Speed Applications
The compact laser distance sensor is offered as a ready-to-use device with industry standard IP67 housing. Designed for measurements of moving targets, the distance sensor is commonly used to detect objects in industrial automation or for monitoring defined areas in transport and logistics applications. Typical applications for the AR2700 include bridge crane monitoring, trolley positioning and altitude measurements, amongst others. Its high sampling rate and ultra-compact case make it ideal for industrial scanning applications and OEM installations with a tight fit.
Outputs and Inputs
The AR2700 high-speed long range sensor is standard with serial and analog outputs. For serial communication, RS232 and RS422 are both included for communication with a computer or PLC. The AR2700 also comes with a standard, 4-20 mA, analog, current loop output. The AR2700 has two limit switches for indicating alarms and can be used for triggering an external device when a target reaches a set position. Data formats are available both in ASCII and Binary with selectable termination characters. This sensor can output its internal temperature and return signal amplitudes in its data stream. The sensor can also be triggered using an input signal wire or a serial command at rates up to 30Khz.
