Siemens 3SF7844-8MD15-0SS1 Safety Light Curtain Receiver, Ty

The 3SF7844-8MD15-0SS1: Type 4 per IEC 61496-1/2 is the highest safety integrity for electro-sensitive protective equipment — it can be used for access guarding where a fault or bypass could cause serious injury. The 30 mm resolution means the curtain detects fingers (30 mm is the minimum object size that reliably breaks a beam), so it suits hand-in-hazard applications like press brakes, assembly stations, and robotic cells. The 1050 mm protected height and 0 to 18 m range cover a typical standing operator zone; muting capability allows automated material handling to pass through without triggering a stop, which is essential for conveyor-fed workstations.
