Light barriers with constant light amplifier (GLV) work with a uniform light beam, making them ideal for detecting small parts and very fast moving parts. The GLV 2.1 plug is equipped with one connection for fork light barriers with small fork width.
Blow-fork light barriers have a compressed air connection, with which the diode is cleaned. This significantly increases reliability and lifetime. Blow-fork light barriers are therefore also well suited for use in environments with increased pollution levels.
