The compact sensors with integrated microcontroller provide a precise output-signal, which is proportional to the measured distance. An intelligent internal system analysis enables the sensor to operate accurately for the majority of surfaces irrespective of their color. Distances to rough surfaces can be measured reliably, when a device is used that has a fine laser line instead of a laser spot. The evaluation electronics generate a mean value for the irradiated area. Using the small visible laser spot the sensor can be aligned easily and exactly. When it is switched on the sensor checks whether or not a current is flowing at the current output. If so, the current output is used, if not then after 100msec the voltage output is used. The alarm output responds through a PNP switch signal, if the measuring range is exited. This is additionally signaled through a red LED lighting up. The resolution is dependent on the position of the object (start/end of the measuring range) and the effective taught-in measuring range. The implemented laser light power tracking ensures that the same signal quality is maintained on both dark and light surfaces and that as a result, the sensor is color-blind. This also compensates for any degree of soiling on the optics. There is an additional synchronization input for time-synchronized measuring tasks, such as the measuring of object thicknesses. Measurements can be started from different sensors at the same time, using an external signal. application examples precise measuring and positioning tasks in many different application areas presence check of various objects monitoring and high-accurate detection of measured values of object heights and pile heights contactless position and thickness measurement of small and large parts color-independent recognition of even the smallest objects

The laser beam hits the object as a small spot. The sensor s receiver detects the position of this spot. In principle the sensor measures this angle and then calculates the distance. Directly in front of the sensor there is a blind range in which objects won t be detected reliably.
