The LDM41A/42A Series of Laser Distance Sensor (Optical Phase Comparison Measurement), manufactured by ASTECH Angewandte Sensortechnik GmbH, is designed as an optoelectronic distance measuring device used for industrial applications. It is built with an analogue interface of 4 mA to 20 mA. This tool can generate precisely accurate measurement of distances, and operates contact-free on the principle of comparative phase measurement.
Moreover, the sensor is available in high precision and high independence from the surface of the measuring object, and is suitable for quick distance measurements on white surfaces.
