Light curtain Siemens Safety

Undesired and unintended intrusions don't stand a chance: Our contactless, active optoelectronic light curtains and grids for categories 2 and 4 according to EN 954-1 or type 2 and type 4 according to IEC/EN 61496-1 protect operators at or near machines and systems in operation. Thanks to specially developed integrated circuits (ASICs) and a patented, intelligent analysis process, they are especially 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 interface 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.
