SICK XC40S-0903A0A00BA0 Safety Light Curtain Sender

XC40S-0903A0A00BA0 is the sender-only component of SICK’s XC40 safety light curtain family, designed for machine guarding in normal industrial environments. It provides a 30 mm resolution over a 21 m maximum scanning range and a 900 mm protective field height, with optical synchronization and an integrated laser alignment aid to simplify setup. The unit runs from a 24 V DC supply (19.2 V to 28.8 V), uses M12, 5-pin connections with a permitted cable length up to 30 m, and utilizes uncoded beams with configurable scanning range and no floating blanking. In safety terms it achieves Type 4 (IEC 61496-1), SIL 3 (IEC 61508), PL e (EN ISO 13849) with PFH of 3.2 × 10^-8 per hour and a 20-year mission time; safe state in fault conditions is that at least one OSSD is OFF. The housing is an aluminum extruded profile, and the device is typically paired with a matching XC40S receiver to form a complete safety light curtain.
