SICK C20S-180303A12 Safety Light Curtain Pair

The SICK C20S-180303A12 Safety Light Curtain Pair comprises a C20S-180303A12 sender and its matching C20E-180303A12 receiver, forming a compact two-piece safety device used to guard hazardous zones on automated equipment. This pair belongs to SICK's C2000 guard family, listed as a standard configuration within the C2000 Standard lineup, and is designed to detect human presence across a defined light-beam field and trigger protective outputs to halt machinery when the beam is interrupted. Typical applications include guarding access to presses, conveyors, robotic cells, and other automation equipment where reliable, non-contact presence sensing is required to prevent injury. The system is engineered for straightforward integration with safety controllers via the unit's safety signaling outputs; exact protective height, beam resolution, sensing range, and electrical specifications vary by variant and are documented on the official C20S data sheet corresponding to 180303A12.
