The SICK MICS3-ABAZ40ZA1P01 is a ultra-compact retro-reflective photoelectric sensor with integrated background suppression functionality. Designed for precise object detection, it emits a red light beam toward a reflector and accurately detects objects within a fixed 40 mm range while ignoring any background interference beyond this distance. Its miniature housing (IP67 rated) ensures reliable performance in space-constrained industrial environments such as automation systems, packaging machinery, and robotic applications.
