Diffuse laser light sensor

Supplier News

WENGLOR, represented in Australia by Treotham Trading , has released the CP08MHT80 diffuse laser light sensor for distance measurement. It has a CMOS line array and is capable of performing highly accurate distance measurements, even with moving objects.

Its high resolution offers fast and precise measurements with minimal linearity error. The diffuse laser light sensor functions almost independently of the colour, brightness and surface characteristics of the object to be scanned. It is also minimally influenced by ambient light.

The CP08MHT80 takes advantage of a high-resolution CMOS line array and a high-performance digital signal processor (DSP) in accordance with the principle of triangulation. Distance information is converted to angular data. More than 1000 pixels along the CMOS line array are the basis for signal processing by means of the DSP.

The results supplied by the sensor are so accurate that it can now be used where mechanical measuring devices were required in the past. It is easy to operate and has a reprogrammable analogue current/voltage output. The analogue output value is proportional to the measured distance from the object to the sensor.

Sensor configuration and querying of settings and measured values is carried out via the RS 232 interface. It has a reprogammable analogue output with voltage and current programmable from 0V to 10V and 4mA to 20mA.

A red laser light makes the sensor easy to align. Working ranges of 30mm to 80mm can be taught in individually. The system has a linearity error of less than 0.1% and a resolution of better than 10µm.
