The Omron F3SJ-A1045P30 is a Type 4 safety light curtain from the F3SJ-A series, designed for hand and arm protection in hazardous machine zones. The 30 mm detection capability means it reliably detects a 30 mm-diameter object anywhere in the sensing field — that is finger-protection class per IEC 61496-1, so it catches hands reaching into the pinch point or press area, not just whole limbs. The protective height of 1045 mm is the actual area covered by the 42 infrared beams, spaced at a 25 mm pitch. For a vertical guarding application, that height covers the reach zone from roughly waist to shoulder height for a standing operator. The operating range spans 0.2 m to 9.0 m, so the emitter and receiver can be set up across a 9 m gap — common for large press brakes or robotic cells. The blanking and muting functions are built in, not optional add-ons. Blanking lets you disable specific beams to allow a fixed obstruction (a fixture or workpiece) through the field without triggering a stop. Muting temporarily suspends the safety output during a non-hazardous portion of the cycle, typically when a pallet or part passes through on a conveyor. Both functions require careful configuration and a risk assessment — the hardware supports them, but the integrator must validate the logic against the machine's safety requirements.
Environmental and supply constraints for panel integration
That means it withstands washdown in a packaging or food-processing line, but not submersion or high-pressure spray (IP67 or IP69K would be needed for those). The 24 VDC supply is standard for safety light curtains; verify the power supply can deliver the inrush current for the emitter-receiver pair without droop. In an unheated warehouse or cold dock area, the lower limit may be tight; the unit should be mounted away from direct drafts or radiant heat sources that push the ambient beyond 55°C.
