The Omron F3SG-4SRA0920-14-F is a Type 4 safety light curtain from the F3SG-SR series, rated for finger detection with a 14mm detection capability and a 920mm protective height. It uses 91 beams at a 10mm pitch, covering a 0.3m to 10.0m operating range. Supply is 24VDC, and the housing is rated IP65/IP67/IP67G — dust-tight, water-resistant, and oil-resistant, suitable for washdown environments. Operating temperature spans -30°C to 55°C.
The 14mm detection capability and 10mm beam pitch mean this curtain catches a finger-sized object — it's not for hand or body detection only. The 920mm protective height covers a typical machine access zone; pair it with a matching emitter and receiver of the same height. The 0.3m minimum range is short enough for tight guarding, and the 10m maximum covers longer conveyor or robot cell perimeters. The IP67G rating adds oil resistance, so it holds up in machining or stamping areas where coolant mist is present.
