LDM42E is an optoelectronic distance measuring device for industrial applications with an integrated Ethernet interface. It works contact-free on the principle of comparative phase measurement (amplitude modulation) and facilitates precisely accurate measurement of distances. Both, the LDM42E and the LDM42E distinguish themselves through high precision as well as high independence from the surface of the measuring object. The red, well visible laser beam allows for easy alignment. The LDM42E has been developed for fast distance measurements on white surfaces. Through the integrated Ethernet interface it is possible to retrieve the measured data in the network via Telnet protocol or to change parameters.
