With a 450 mm protected height and a 0 to 6 m operating range, this receiver pairs with a matching emitter to create a safety barrier that covers a standard machine opening — think press brakes, assembly stations, or robotic cells where personnel access must be interrupted before a hazardous motion starts. The integrated PROFIsafe bus connection means it talks directly to a F-CPU (fail-safe controller) over a standard PROFINET network, eliminating a separate safety relay or interface module in the cabinet. Muting capability is built in, so it can be temporarily overridden during material feed cycles without tripping the safety circuit. Type 4 per IEC 61496-1 is the highest safety integrity level for electro-sensitive protective equipment (ESPE), capable of detecting a 14 mm object across the full height — that is finger detection, not just hand or body detection. For a press or robot cell, this is the category that allows Category 4 / PL e / SIL 3 safety system architecture without an additional safety mat or interlock. The 450 mm protected height and 0 to 6 m range cover a typical small-to-medium machine opening. If your guard spans wider than 450 mm, you stack multiple receiver-emitter pairs; if the range needs to exceed 6 m, this part is not the fit — it is optimized for shorter, higher-resolution zones. PROFIsafe connection transmits the safety signal over the standard PROFINET network using the PROFIsafe profile.","metaTitle":"Siemens 3SF7844-8MB06-0SS1 Light Curtain Type 4 Receiver, 14","metaDescription":"Siemens 3SF7844-8MB06-0SS1 Type 4 safety light curtain receiver, 14 mm resolution, 450 mm height, 0-6 m range, PROFIsafe, SIMATIC FS450I.
