These sensors work with a high resolution CMOS line and DSP technology and calculate the distance via an angle measurement. This virtually eliminates switching point differences caused by material, color and brightness. Two independent switching outputs are available, at which two switching thresholds and one on-delay or off-delay time can be set in 10 ms increments. Sensor functions can be activated and values can be output via the RS-232 interface.
In automotive shell construction, body parts such as doors, tailgates or fenders are stacked in load carriers. Robots load and unload these carriers. To enable the robot to grip precisely, a high-precision laser distance sensor mounted on the gripper determines the distance to the first component that is removed. The robot’s lateral approach and gripping process are optimally controlled by the two independent switching outputs. Even on shiny surfaces, the sensor works very precisely with CMOS line images.
High-Precision Laser Distance Sensors
High-precision laser distance sensors work according to the principle of angle measurement, whereby color, shape and object surface do not influence the measurement. Depending on the setting, they can be operated at very high speed or resolution. The measuring range can be selected individually within the sensor’s working range.
