The Omron F3SG-4SRB0280-14-F is a safety light curtain from the F3SG-SR series, built for finger detection with a 14 mm detection capability and a 10 mm beam pitch across 27 beams. That 14 mm resolution means it catches a finger before it reaches the danger zone — the standard spec for hand/finger protection at access points. Protective height is 280 mm, and the operating range stretches from 0.3 m out to 10.0 m, so it covers a mid-sized opening on a machine cell or conveyor infeed.
Runs on 24 VDC, which is the standard control voltage in most panels — no extra power supply needed if you've already got a 24 V bus. The enclosure is rated IP65/IP67/IP67G, meaning it's dust-tight, resistant to oil, and can handle temporary submersion plus a higher-pressure washdown (the G suffix). Operating temperature from -30°C to 55°C covers freezer environments and hot factory floors without derating.
Packaged in bulk, so it ships as a single unit with the emitter and receiver pair — no separate ordering of transmitter and receiver. The 27 beams at 10 mm pitch give a 280 mm protective field, which is a common height for guarding a small press or a robot cell entry. If you're replacing an older Omron or another brand's 14 mm curtain, this one's a direct functional match for that class.
