Thanks to specially developed integrated circuits (ASICs) and a patented, intelligent analysis process, they are espe- cially fail-safe and highly available. Whether protecting body parts, securing horizontal hazardous areas or the access to larger areas - the widest range of functions such as start and restart locking, contactor monitoring, jog control or blanking allow for many different applications. A version for connecting to the AS inter- face is available.
A light curtain or light grid comprises a transmitter and a receiver, which must be mounted opposite each other. Depending on the resolution and the length, a certain number of transmit and receive diodes are arranged vertically. The infrared LEDs of the transmitter emit short light pulses that are detected by the receive diodes.
