The Omron F3SG-4SRA0160-14 is an active-production light curtain from the F3SG-SR series, built for finger protection with a 14 mm detection capability and a 160 mm protective height. It uses 15 beams on a 10 mm pitch to cover an operating range from 0.3 m out to 10 m. Rated IP65/IP67/IP67G, it's sealed against dust, water jets, and oil — so out here in the grease, it'll hold up where a lot of delicate sensors won't.
The 14 mm detection capability means this curtain catches a finger before it reaches the danger zone — that's the spec that decides whether it's right for your machine's risk assessment. The 160 mm protective height and 15 beams give you a 150 mm effective sensing field (beam 1 to beam 15), so it fits openings just over that tall.
Mounts into a standard safety light-curtain setup — emitter and receiver pair, aligned across the hazardous opening. The blanking and muting functions let it ignore fixed obstructions or pause during a material feed cycle, which saves you from having to wire around the curtain. IP67G adds oil resistance, so it's at home on a machining center or a press where coolant mist is the norm.
