SICK FGSE450-23 Safety Light Curtain Receiver

The FGSE450-23 is a SICK safety light curtain receiver (1012589) in the FGS family with a 30 mm resolution and a protective height of 482 mm, delivering Type 4 safety performance when paired with a compatible sender. Designed as the receiver unit only, it operates on 24 VDC with a nominal power consumption of 11 W and weighs about 4.06 lb. As part of the FGS series, this device is used to monitor the beam path of a safety light curtain to guard hazardous machine areas and trigger a safety interlock or stop circuit on beam interruption. The FGSE450-23 is compatible with standard FGS system configurations and is often referenced in catalogs as FGSE450-23 (also listed as FGS-E450-23 in some sources). This model is noted as discontinued by the manufacturer, affecting availability and support for new deployments. Ensure any replacement aligns with the same 30 mm resolution, 482 mm height, 24 VDC supply, and Type 4 safety requirements to maintain equivalent protective performance.
