The L-LAS-RL series
L-LAS-RL sensors are reflective line sensors from Sensor Instruments in which a diffuse light source combined with a CCD line detector is incorporated into one housing. The light source consists of 9 white LED diodes whose light shines homogeneously on the measurement surface using a diffuser. The reflected light from the LED diodes landing on the CCD is visualized in a video signal. Dips or peaks in light intensity can indicate a transition from light to dark, changes in distance or the angle of an object. Because the position in this video signal can be converted to a distance, a measurement can be made at the micrometer level. The sensor has a working distance 55 mm with a measuring range of about 20 mm. Settings can be made via a teach button, as well as via the included parameterization software for Windows. The sensors have an analog output (0-10Vdc or 4-20 mA), 3 digital outputs and are equipped with an RS232 interface.
