SICK C40S-0903AA030 Safety Light Curtain Sender

The SICK C40S-0903AA030 Safety Light Curtain Sender is the sending half of a two‑part barrier in SICK’s C4000 Basic family, designed to safeguard hazardous points on automated equipment by emitting a synchronized light curtain that pairs with a matching receiver. It delivers 30 mm resolution over a 6 m scanning range and protects a 900 mm‑high field, enabling reliable detection of intrusions within that zone. Optical synchronization with the receiver helps maintain beam alignment in environments subject to vibration or temperature changes, reducing nuisance faults and ensuring quick, deterministic safety signaling. The part number C40S-0903AA030 uniquely identifies this 30 mm variant of the C40S line for use with compatible SICK safety controllers and receivers to form a complete safety curtain for machine guarding and controlled access in manufacturing environments. For exact electrical connections, mounting notes, and safety ratings, refer to the official C4000 data sheet.
