What the 14mm detection means for your guarding layout
The Omron F3SJ-A0263P14 is a Type 4 safety light curtain from the F3SJ-A series, rated for finger detection with a 14mm detection capability. That 14mm resolution means it catches a finger reaching into the hazard zone — finger-protection class per IEC 61496-1 — so it's the right choice for access points where operators might reach through, not just walk past. The 28 infrared beams at 9mm pitch create a 263mm protective height, covering a 263mm vertical zone from the first to the last beam. Operating range spans 0.2m to 9.0m, so it works on a compact assembly station or across a wider conveyor gap. The 24VDC supply is standard for safety circuits tied to a safety PLC or safety relay.
Features that matter on the line
Built-in blanking and muting functions let you configure the light curtain around fixed obstructions (like a conveyor frame) or suppress it during a material pass cycle without removing safety coverage elsewhere. That saves an external muting module and simplifies the wiring in the panel.
