The F3SJ-A0317P14 is a Type 4 safety light curtain from the F3SJ-A series, built for finger-protection duty. Its 14 mm detection capability means it catches individual fingers reaching into the hazard zone — finger-protection class per IEC 61496-1. That 14 mm figure is the minimum object size the curtain detects, so it's the spec that decides whether this unit guards a press, a pick-and-place cell, or a packaging machine where hand access is possible. Protective height is 317 mm, spanned by 34 beams on a 9 mm pitch. The operating range runs from 0.2 m to 9.0 m, which covers short-reach guarding up to mid-span access points. Supply is 24 VDC, standard for safety relay or safety PLC inputs.
IP65 rating means the emitter and receiver housings handle washdown and dust — suitable for food-and-bev lines, machining centers, and packaging floors where hoses are part of the cleaning cycle. Blanking and muting functions are built in, so the curtain can ignore fixed obstructions (blanking) or be temporarily overridden during material pass-through (muting) without disabling the safety output. That keeps production moving while maintaining protection.
No broker channel required, no end-of-life paperwork. The series is well-established, so replacement optics and mounting hardware are available through normal distribution.
