SLG25S-050FAR21D40 – SICK

The SLG25S-050FAR21D40 is a self-contained automation light grid from SICK, operating on a 24 VDC power supply. It features a 50 mm beam separation (FAR designation), providing a monitored field height dependent on the number of beams. The “S” in the part number indicates a slim housing profile. The R21 denotes a radial cable exit, and the D40 likely refers to a specific digital output configuration, potentially push-pull or PNP/NPN selectable, requiring detailed datasheet review for confirmation. The light grid is designed for object detection and presence monitoring in automated systems, outputting a signal based on beam interruption. Its robust construction and ingress protection rating (likely IP65 or higher, requiring datasheet verification) make it suitable for industrial environments. Precise range and response time are critical parameters that must be confirmed in the official SICK documentation for proper system integration.
