The Omron F3SJ-B0705N25 is a safety light curtain from the F3SJ-B series, with 25 mm detection capability, 20 mm beam pitch, 34 beams, 705 mm protective height, and 0.2 m to 7.0 m range. IP65 rated.
The 25 mm detection capability and 20 mm beam pitch mean this curtain catches a hand or finger-sized object reaching into the hazard zone — it's a hand-protection device per IEC 61496-1, not fingertip. The 705 mm protective height covers a typical standing operator's reach across a machine opening; pair it with a second curtain if the aperture is taller. The 0.2 m minimum range allows mounting close to the machine frame, while the 7.0 m maximum covers most single-side guarding layouts.

Integration notes
Blanking and muting functions are built in, so you can program fixed or floating blanking to ignore a stationary object (e.g., a fixture) in the field, and muting to temporarily bypass the curtain during a material pass-through. The 24 VDC supply is standard for safety controllers and relay modules. Mounting brackets and alignment aids are typically ordered separately — the curtain itself ships in bulk packaging.
