The Omron F3SJ-A0395N30 is a type-4 safety light curtain from the F3SJ series, built for hand and arm detection at the hazard zone. The 30 mm detection capability means it catches a finger or hand reaching past the curtain — that is the resolution that decides whether it guards a press, a robot cell, or a conveyor infeed. The 395 mm protective height covers a vertical opening just under 400 mm; if your guarding aperture is taller, you stack multiple units or step up to a longer F3SJ variant. The 0.2 m to 9.0 m operating range gives flexibility for short-reach stations or longer spans across a cell. Sixteen beams create the detection plane, and the 24 VDC supply is standard for safety circuits. Blanking and muting functions are built in, so the curtain can ignore a fixed object (blanking) or temporarily suspend detection during a workpiece pass (muting) without external logic modules. That saves panel space and wiring on a machine that cycles parts through the guarded opening.

Product details
Frequently asked questions
What is the detection capability and what does it mean for guarding?
The detection capability is 30 mm, which qualifies as hand/arm protection per IEC 61496. It detects a 30 mm diameter object — roughly a finger or hand — entering the protected area.
What is the protective height and operating range?
The protective height is 395 mm, and the operating range is 0.2 m to 9.0 m. The height determines the vertical zone covered; the range sets how far the emitter and receiver can be spaced.
Does this light curtain support blanking or muting?
Yes, blanking and muting functions are included on this model, allowing fixed object bypass and temporary suspension during material handling without external controllers.
What ingress protection rating does it carry?
IP65 — dust-tight and protected against water jets, suitable for washdown environments.
