General information

The sensors are intended for non-contact measuring and checking of position, displacement, dimensions, surface profile,

deformation, vibrations, sorting and sensing of technological objects as well as for measuring levels of liquid and bulk materials.

The series includes 26 sensors with the measurement range, from 2 to 1250 mm and the base distance from 10 to 260 mm.

There are two options of laser mounted in the sensor, RED or BLUE laser. The use of blue lasers instead of conventional red lasers

greatly enhances capabilities of the sensors, in particular, for such uses as control of high-temperature objects and organic

materials. Custom-ordered configurations are possible with parameters different from those shown below.

Note 1: All the values are given for white matt surfaces and may vary for the surfaces with other characteristics.
Note 2: LDE-HS-R-39/4 sensor is designed to use with mirror surfaces and glass.

Operation of the sensors is based on the principle of optical triangulation. Radiation of a semiconductor laser 1 is focused by a lens 2 onto an object 6. Radiation reflected by the object is collected by a lens 3 onto a linear CCD-array 4. A signal processor 5 calculates the distance to the object from the position of the light spot on the array 4.




The sensors are intended for non-contact measuring and checking of position, displacement,
dimensions, surface profile, deformation, vibrations, sorting and sensing of technological objects.
