Type 4 per IEC 61496-1/2 means it is certified for the highest safety integrity — suitable for guarding hazardous machine zones where a failure must not lead to loss of the safety function. The 30 mm resolution detects fingers (hand protection) reaching into the field. Blanking allows fixed or floating objects (e.g., workpiece fixtures) within the field without tripping the safety output, while the full 18 m range covers long access openings on large assembly or packaging lines. ## Integration Notes PROFIsafe bus connection integrates directly into a Siemens F-CPU without an external safety relay.","metaTitle":"Siemens 3SF7844-8BD06-0SS1 Safety Light Curtain, Type 4, 30","metaDescription":"Siemens 3SF7844-8BD06-0SS1 Type 4 safety light curtain receiver, 30 mm resolution, 450 mm height, 0–18 m range, PROFIsafe.
