LDM42 series industrial LASER distance meters
The LDM42A LASER distance meters are optoelectronic distance sensors for industrial applications, such as distance and position measurement without the use of special reflectors.
The target can be any type of natural surface. The sensor works based on the comparative phase measurement.
It emits a modulated laser light which is diffusely reflected from the target with a certain phase shift to be compared with a reference signal.
From the amount of phase shift, the required distance can be determined with pinpoint accuracy.

Insights
The industrial LASER distance meters of the LDM40 series are used for the distance measurement from a few millimeters up to 100 meters. The distance measurement represents aconsolidated application for laser technology.
Industrial LASER distance meters use LASER light (pulse or modulated) to measure distances, heights, lengths, levels and positions without any contact with the object to be measured.
LASER distance meters consist of a laser emitter, optical transmitters and receivers, photosensitive diodes and sophisticated electronics with algorithms for time measurement or phase measurement. The distance measurement is obtained using different optoelectronic principles such as flight time, phase comparison and LASER pulse with "back-mixing" technology.
These methods allow singles accurate measurements to the millimeter, and measuring ranges up to several tens of meters.
Using LASER distance meters is possible measure on natural surfaces or on special reflectors obtaining fast and precise results even in harsh conditions.
The LASER distance meters work using visible or infrared optical radiation and are classified in accordance with the regulations in force in class 1 or 2 (safe classes for operation even without protective goggles).
The compact construction allows easy installation of the LASER distance meter even where space is limited or in industrial applications. All devices offer standard interfaces, analog or digital data output and customizable switching outputs.
The family of LASER LDM distance meters is particularly used for applications in the industrial sector with analog (4 - 20 mA) or digital (Ethernet, Profinet, Profibus, RS232, RS422, SSI ).
