LDM41EI and LDM42EI
Laser distance measurement with EtherNet/IP
The LDM41EI is an optoelectronic distance measuring device for industrial applications with EtherNet/IP interface.
It works contact-free on the principle of comparative phase measurement (amplitude modulation) and facilitates precisely accurate measurement of distances.
Funktion
Both, the LDM41EI and the LDM42EI 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 LDM42EI has been further developed for fast distance measurements on white surfaces.
Through the integrated EtherNet/IP interface it is possible to read in data of several devices into a control easily.
