The SICK OD1-B035C15Q15 is a Type 4 (according to IEC 61496-1/2) self-contained safety light curtain from SICK's OD1 Mini series. It is specifically engineered for access monitoring and perimeter guarding on small to medium-sized machinery and automated cells. Unlike fine-resolution models for finger protection, this variant is designed to detect the presence of a person's entire body or larger objects.
