The F3SJ-B0305P25 is a 14-beam safety light curtain from the F3SJ-B series, with a 25 mm detection capability that qualifies it for hand protection per IEC 61496 — meaning it catches fingers reaching into the hazard zone, not just a full hand or arm. The 20 mm beam pitch and 305 mm protective height define the guarded area: a 305 mm vertical zone where any opaque object 25 mm or larger breaks the beam and triggers the safety output. Operating range spans 0.2 m to 7.0 m, so it works for both tight machine guarding (under a meter) and wider access points up to 7 meters between emitter and receiver.
Blanking and muting — what they do for the line
Built-in blanking and muting functions let this curtain ignore fixed obstructions (blanking) or temporarily suspend guarding during a material pass (muting). Blanking is useful when a machine frame or conveyor rail sits inside the detection zone — you program the curtain to ignore those beams. Muting requires external sensors to signal a pallet or workpiece entering the zone, so the curtain suppresses its safety output only during the intended pass, then re-arms. Both features reduce nuisance trips that stop production.
No surplus or broker channel needed — the part is factory-current.
