FR 20 RLO

Retro-re ective laser light barrier with autocollimation

Features

• Autocollimation principle (emitter/receiver beam on one axis)• Laser protection class 1 • Scanning range 4000 mm • High precision - very good detection of small parts (from 0.2 mm)• Excellent detection of cylindri-cal objects• High reproducibility, no mat-ter if the target object cuts the light beam horizontally or vertically• Small light spot over the whole detection range • Objects can be detected at close range

Light. Reliable. Precise.

This retro-re ective light barrier in a miniature casing has a homogenous small light spot over the whole detection range. Emitter and receiver beam run on one axis (autocollimation), therefore it is possible to detect objects even through small holes. This sensor opens up many new application possibilites as it recognizes objects at close range, does not require any protective measures thanks to laser protection class 1, and as it works very precisely. The setting is made by teach-in, either by push-button or by external teach. In combination with the function "dynamic teach-in", setting by external teach is also possible when the sensor is mounted in a place which is not easily accessible.
