Euchner Light Curtains


LCA light curtains are non-contact safety guards for securing danger areas on machines and installations. They use several light beams to form an invisible safety light curtain in front of a dangerous area. The light curtain consists of a transmitter and receiver that emit and receive the light beams. If a beam is interrupted, the light curtain safety outputs will switch off.

LCA light curtains are available in several beam resolutions as seen here:

    Finger protection    Hand protection   Body protection    Access
