The SICK MICS3-AAAZ55AZ1P01 is a miniature, self-contained background suppression photoelectric sensor housed in a compact plastic body. It is designed for precise detection of objects at a short range, utilizing an advanced optical system that measures the distance to the target. This allows it to reliably detect objects regardless of their surface color, material, or reflectivity, as it ignores any objects beyond the set sensing distance.
