Light Grids/Light Curtains LCA 2
EN
A distinction is made between two device types:
Light grids
produce a protective field consisting of 2 – 4 light beams. Due to the large spacing between the individual light
beams, these devices can be used only for body protection.
Light curtains
consist of a large number of light beams. These devices can detect different body parts depending on the
resolution (30 – 50 mm). A distinction is made between hand and body protection.
