The Omron F3SG-4RE0720P14 is a Type 4 safety light curtain from the F3SG-RE series, rated for finger detection with a 14mm detection capability. That 14mm resolution means it catches fingers reaching into the hazard zone — finger-protection class per IEC 61496-1 — so it's the right choice for access guarding where hand entry is possible but arm/body passage isn't expected. The 720mm protective height, delivered by 71 beams at a 10mm pitch, covers a vertical zone from roughly ankle to mid-thigh on a standing operator. The 0.3m to 10.0m operating range gives flexibility for both tight machine cells and wider conveyor access points. IP67 sealing means the sensor heads and optics handle washdown environments — food, beverage, or wet machining lines — without condensation or ingress issues.
Integration Notes
Runs on 24VDC, which is standard for safety circuits in most panels. The 71-beam array means the controller has to process 71 channels; verify the safety CPU has enough input capacity and that the response time calculation includes the full beam count. The 10mm beam pitch gives good resolution for finger detection, but also means more beams to align during commissioning — expect a slightly longer setup compared to a 30mm hand-protection curtain.
