What the 25 mm detection capability means for fit
This means it catches a hand or finger reaching into the hazard zone — the 20 mm beam pitch and 70 beams create a detection plane that a 25 mm diameter object cannot pass through without triggering the safety output. For a cold-storage or food-processing line where operators load product through a guarded opening, this resolution stops a hand before it contacts a conveyor nip or palletizer clamp.
Protective height and range — guarding the full opening
The 1425 mm protective height covers the vertical reach zone of a standing operator, so a single curtain guards a typical infeed or egress opening without stacking multiple units. The operating range spans 0.2 m to 7.0 m, which suits both tight machine guarding (a press or robot cell) and wider conveyor access points. At 24 VDC supply, the emitter and receiver pair draw from the same safety controller loop — no separate power supply needed if the controller provides 24 V.
IP65 and washdown environment
Rated IP65, the F3SJ-B1425P25 is dust-tight and protected against water jets. In a cold-chain or food-processing line where washdown cycles are daily, the sealed housing keeps moisture out of the optics and electronics.
Blanking and muting — flexible for material handling
Built-in blanking and muting functions let the curtain ignore fixed obstructions (a conveyor frame or product chute) or temporarily suspend the safety output during a pallet pass-through. For a cold-storage dock where pallets enter a freezer, muting allows the load through while maintaining hand protection for personnel. These are on-board features, not add-on modules — set them via the teach pendant or software during commissioning.
