Light Grids/ Light Curtains LCA 4
EN
A differentiation 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 only be used for body protection.
Light curtains consist of a large number of light beams. These devices can detect different body parts depending on the
resolution (14 – 50 mm). A distinction is made between finger, hand and body protection.
