SICK C4P-SA09031A00|C4P-EA09031C00 Light Curtain Sender Receiver Set

The SICK deTec4 light curtain sender-receiver set, model C4P-SA09031A00 / C4P-EA09031C00, delivers 30 mm resolution over a 30 m scanning range with a 900 mm protective field height to guard access to hazardous zones on automated machinery. The pair uses optical synchronization, includes an integrated laser alignment aid and end caps with LED indicators, and is rated Type 4 with PL e and SIL 3 for safety in a normal industrial environment. Included in the box are the C4P-SA09031A00 (sender) and C4P-EA09031C00 (receiver), system plugs SP1-1100 and SP2-2100, four FlexFix brackets, two M12 protective caps for the female connectors, and a test rod matched to the 30 mm resolution. The receiver provides two PNP OSSD outputs and a diagnostic/status output, powered from 24 V DC, and the housing offers IP65/IP67 protection with an aluminum extrusion. The safety performance is quantified with PFH values of 15.3 x 10^-9 per hour for a single device, 30.5 x 10^-9 per hour in cascade with one guest device, and 45.6 x 10^-9 per hour in cascade with two guest devices; response times are 11 ms when uncoded and 17 ms for Code 1 or Code 2, with 900 mm field height and 30 m reach enabling reliable guarding across larger work cells.
