The 3SF7844-8TB06-0SS1 is a Siemens SIMATIC FS420I Type 4 safety light curtain receiver with 14 mm resolution and a 450 mm protected height. It connects via PROFIsafe bus to a SIMATIC FS420I safety controller. The 14 mm finger-protection resolution means it detects objects as small as a finger reaching into the hazard zone — that's the detection capability for hand/finger safety per IEC 61496-1 Type 4, the highest integrity level for electro-sensitive protective equipment. The 0 to 6 m operating range covers most machine guarding distances without needing a secondary lens.
