The Omron F3SJ-A0407P14 is a Type 4 safety light curtain from the F3SJ-A series, built for finger detection at 14 mm resolution. That 14 mm detection capability means it catches fingers reaching into the hazard zone — finger-protection class per IEC 61496-1 — so it guards access points where hand entry is possible but arm/body entry is not. The 407 mm protective height and 44 beams cover a vertical zone just over 40 cm tall; pair it with a second curtain if the opening is wider. Operating range spans 0.2 m to 9.0 m, which covers most machine guarding distances from close-in press feeds to conveyor in-feed stations. The 9 mm beam pitch is tight enough for finger detection at that 14 mm specification — the pitch defines the gap between optical axes, and the detection capability is the smallest object the curtain reliably blocks. Runs on 24 VDC, the standard safety-circuit supply. IP65 rating means the housing and optics withstand washdown — suitable for food-and-bev lines or any area where hosing is part of the cleaning cycle.
Blanking and muting — what they mean on the line
Blanking lets you disable specific beams to allow fixed objects (like a conveyor frame or part fixture) to pass through the curtain without triggering a stop. Muting temporarily suspends the curtain during a defined material pass cycle — think a pallet entering a robot cell. Both features are built into the F3SJ-A0407P14, so you don't need an external bypass module.
