What the 25 mm detection means for guarding
The protective height is 1105 mm, with 54 beams at 20 mm pitch.
Range and mounting constraints
Operating range spans 0.2 m to 7.0 m, so the emitter and receiver can be spaced across a conveyor or machine cell up to 7 meters apart. The minimum 0.2 m standoff means you cannot mount the pair flush against each other — there is a dead zone close to the emitter face. IP65 rating means the housings tolerate washdown splashes and dust, suitable for food-processing or automotive assembly environments where hoses are used. Supply is 24 VDC, standard for safety circuits; plan for a dedicated safety-rated power supply or a fused tap from the machine's 24 V bus.
The F3SJ-B1105P25 carries an end-of-life (EOL) status, meaning Omron has formally discontinued this order code. No successor part number is listed in the lifecycle record. If the machine design allows a different protective height or beam count, a parametric search across the F3SJ-B family may yield an active variant, but no pin-compatible drop-in replacement is documented here.
Feature set for the integrator
Blanking and muting functions are built in, so the curtain can ignore fixed obstructions (blanking) or automatically bypass during a material pass-through cycle (muting). These are configured via the controller, not the sensor heads themselves — verify the controller model supports the feature set before wiring.
