Light barrier is a term used to describe light curtains that have multiple single beams and so can be used in applications up to Category PL e. Like light curtains, light barriers with semiconductor outputs are suitable for all Type 2 and 4 applications in accordance with EN/IEC 61496-1/-2 and for Type 3 applications in accordance with EN/IEC 61496-1.
Application area for light curtains
A light curtain is used in industries and applications that require high productivity with simultaneous intervention by the operator. Some examples include presses, packaging machines, machining centres, robot systems, assembly lines, as well as transport and conveyor systems on which a light curtain is used.

Light barriers PSENopt Advanced also provide the opportunity to implement muting, blanking and/or cascading with just one light barrier. As the single beams can be shown in the software PSENopt Configurator, it is much easier to align and monitor the light barriers and reaction times can be reduced to a minimum through rapid diagnostics.
