Integrator's quick-fit note
The Omron F3SG-4SRA0840-14-F is a type-4 safety light curtain from the F3SG-SR series, rated for finger detection with a 14mm detection capability and 10mm beam pitch across 83 beams. Protective height is 840mm, operating range spans 0.3m to 10.0m. Supply is 24 VDC. Enclosure rating IP65/IP67/IP67G covers dust, oil, and water immersion — suitable for washdown zones. Temperature range -30°C to 55°C covers freezer lines and hot process areas.
The 14mm detection capability and 10mm beam pitch mean this curtain catches a finger-sized object before it reaches the danger zone — that is the difference between a finger-safe and a hand-safe curtain. The 83 beams at 10mm pitch give the 840mm protective height; if your opening is taller, you stack multiple units. The 0.3m minimum range is short enough for tight machine guarding; the 10m maximum covers most single-side installations. Blanking and muting functions are built in, so you can program fixed obstructions or cycle-disable the curtain for material feed without an external controller.
