What this part is and what it guards
The Omron F3SJ-A0995P30 is a Type 4 safety light curtain from the F3SJ-A series, rated for hand and arm detection with a 30mm detection capability. That 30mm figure means it catches a hand or arm reaching into the hazard zone — finger-protection class per IEC 61496-1 would need a smaller beam pitch, but for palm and forearm this is the standard spec. The 40 beams at 25mm pitch cover a 995mm protective height, giving you a guarded zone that suits conveyor infeed, assembly station access, or robot cell perimeters.
Key ratings and what they mean for fit
Operating range spans 0.2m to 9.0m — short enough to mount close to the hazard for a compact cell, long enough to cover a wide access opening across a gantry aisle. The 24VDC supply is standard for safety circuits; you'll pull power from the safety relay or controller's 24V bus. IP65 rating means the emitter and receiver housings are dust-tight and protected against water jets — suitable for washdown environments in food processing or automotive machining lines, though not for submersion. Blanking and muting functions are built in. Blanking lets you disable specific beams to allow a fixed obstruction (like a fixture or conveyor frame) through the field without tripping the safety output. Muting temporarily suspends the light curtain during a defined material pass cycle — think a pallet moving through the guarded opening while the machine runs. Both are configurable, so the integrator doesn't need an external bypass module.
Deployment context
Mounts via the standard end-bracket and column hardware for the F3SJ-A series — alignment to the receiver is critical; the manual specifies a ±2.5° angular tolerance. The 995mm protective height and 30mm detection capability mean this is sized for a reach-through hazard zone where a hand could enter but not a finger. Typical deployment: guarding the load/unload opening of a press brake, a packaging machine infeed, or a robotic workcell gate.
