LDM41A and LDM42A
Laser Distance Measurement Sensors
T
he LDM41A is an optoelectronic distance measuring device for industrial applications with an analogue
interface (4 mA to 20 mA).
It works contact-free on the principle of comparative phase
measurement (amplitude modulation) and facilitates precisely
accurate measurement of distances.
It distinguishes itself through high precision as well as high
independence from the surface of the measuring object. The
red, visible laser beam allows for easy alignment.
The sister model LDM42A has been further developed for
fast distance measurements on white surfaces.
Key Features
