With 49 beams at a 25 mm pitch, it covers a 1220 mm protective height. The operating range spans 0.2 m to 9.0 m, so it works for both tight machine guarding and wider access points on a production line. Rated IP65 — dust-tight and protected against water jets — so it handles washdown environments in food processing or automotive assembly without needing an extra enclosure. Supply is 24 VDC, standard for safety circuits in a control panel.
The F3SJ-A series is a mature safety light curtain family. If you're kitting a new machine design, verify that the 30 mm detection and 1220 mm height still match your risk assessment; the series has been stable, but always confirm the latest documentation for your safety certification package.
Mounting brackets and alignment aids are typically ordered separately for the F3SJ-A series — the curtain itself ships bulk. The 24 VDC supply and PNP safety outputs (OSSD) connect directly to a safety PLC or safety relay module; blanking and muting functions are built in, so you can configure fixed or floating blanking for conveyor pass-through without an external controller. The 9.0 m maximum range gives flexibility for longer guard zones.
