LCA 4 Light Curtains


EUCHNER 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 spacings (resolution) and lengths (protected heights). Available in Protected Heights range from 160 to 1810mm. Depending on the model, the transmitter and receiver can be mounted up to 6, 12 or 20 meters apart.
