The 450L safety light curtains are unlike traditional safety light curtains, which are based on separate transmitter and receiver units. Patented technology allows each transceiver to be used as a transmitter or receiver via an innovative plug-in module. The 450L-E option provides advanced functionality, including integrated laser alignment, cascading, blanking and integrated muting.

The 450L safety light curtains are TÜV certified PLe, Type 4 IEC 61496-1/-2, SIL CL3 per EN ISO 13849-1 and IEC 62061.
