Its 62 beams at 20 mm pitch create a 1265 mm protective field with a 0.2 m to 7.0 m range. Rated IP65, the emitter and receiver housings resist dust ingress and water jets from any direction. That makes the F3SJ-B1265N25 suitable for washdown environments in food processing, packaging, or automotive machining lines where hose-down cleaning is routine. The 24 VDC supply keeps integration straightforward with standard safety controllers and PLC outputs.
The 25 mm detection capability classifies this as hand protection — it detects a 25 mm diameter test rod. The 1265 mm protective height covers access openings for a standing operator. The 20 mm beam pitch gives a resolution finer than the 25 mm detection capability, which means the curtain catches a hand reaching through at any angle. The 62 beams overlap to eliminate blind spots between adjacent beams, a common failure point on older two-beam systems.
