The Omron F3SJ-A0445P30 is a Type 4 safety light curtain from the F3SJ-A series, designed for hand and arm detection at industrial access points and hazardous zones. Its 30mm detection capability and 25mm beam pitch mean it catches a hand or arm reaching through — the standard finger-protection class per IEC 61496-1 for hand/arm safeguarding — not just a presence beam. The 445mm protective height and 18 beams cover a vertical aperture of that height; the operating range spans 0.2m to 9.0m, so it fits both tight machine cells and longer conveyor or robot-cell perimeters.
This part carries an end-of-life (EOL) status, meaning Omron has discontinued production.
Deployment context and ratings
The 24VDC supply is standard for safety circuits. Built-in blanking and muting functions let the curtain ignore fixed obstructions (like a conveyor frame) or temporarily suppress the beam during a material pass cycle, which saves wiring external bypass relays.
