SICK C41S-0903AA300 Micro Safety Light Curtain

The SICK C41S-0903AA300 is a C4000 Micro safety light curtain sender unit designed to guard hazardous machine points in automated equipment. It operates from a 24 V DC supply and draws up to 4.3 W, with an M12 male connector for system wiring. Part of the C4000 Micro family, this compact sender works with a matching receiver to form a light curtain that monitors access to the protected area. Typical applications include safeguarding around presses, conveyors, and robotic work cells where interruption of the light curtain stops the machine. The C4000 Micro line is described by SICK as a cost-efficient protection solution for access to hazardous points, and the "C41S" designation identifies the sender component within a two-piece C4000 Micro system.
