The Omron F3SG-4SRB0760-85 is a Type 4 safety light curtain from the F3SG-SR series, built for point-of-operation and access guarding on automated machinery. Its 85 mm detection capability means it catches a hand or arm entering the field — finger detection it is not, but for full-body or limb access at a 760 mm protective height it is the right resolution. The 80 mm beam pitch with 10 beams covers that height with no blind zones between beams. Operating range runs 0.3 m to 20.0 m, so you can mount the emitter and receiver across a conveyor line or a robotic cell aisle without worrying about range limits. Supply is 24 VDC, standard for safety circuits. The enclosure carries IP65/IP67/IP67G — dust-tight, protected against immersion, and the IP67G variant adds oil resistance for washdown zones in food or automotive lines. Built-in blanking and muting functions allow the curtain to ignore fixed obstructions (like a machine frame) or temporarily bypass during a workpiece pass-through — no external controller needed for basic muting logic. Temperature range of -30 °C to 55 °C covers cold storage areas and hot factory floors without derating.

Frequently asked questions
What does the 85 mm detection capability mean for my application?
The 85 mm detection capability means the light curtain reliably detects objects at least 85 mm in diameter — roughly hand or arm size. It is not suitable for finger detection (typically 14 mm), but it is correct for full-body or limb access guarding at the 760 mm protective height.
Can this light curtain handle washdown environments?
Yes. The IP65/IP67/IP67G rating means it is dust-tight, protected against temporary immersion (IP67), and the IP67G variant adds oil resistance — suitable for food processing or automotive lines that see high-pressure washdown and cutting fluids.
What is the operating range and supply voltage?
The operating range is 0.3 m to 20.0 m, and the supply voltage is 24 VDC. This covers most machine guarding distances and integrates with standard 24 V safety circuits.
Does this model support blanking and muting?
Yes, the F3SG-4SRB0760-85 includes blanking (to ignore fixed obstructions) and muting function (to temporarily bypass the curtain during material pass-through) as built-in features.
