The Omron F3SG4PGA06702C is a two-beam safety light curtain from the F3SG-PG series, designed for point-of-operation guarding where a single beam pair won't provide adequate coverage. The 500 mm beam spacing and 670 mm protected height mean it covers a vertical zone of about 670 mm with two infrared beams at 870 nm — the spacing is wide enough for perimeter access detection but not for finger or hand protection (those require tighter spacing, typically 14 mm or 30 mm). The 5 m maximum sensing range gives you room to mount the transmitter and receiver across a machine opening or conveyor entry. Rated for 24V DC operation, the safety outputs (OSSD) are rated at 300 mA each, which is typical for driving a safety relay or safety PLC input module. The auxiliary output is configurable as NPN or PNP at 100 mA — handy for feeding a status lamp or a non-safety controller without an extra interface. Response time is 8 ms maximum, so the curtain will signal a stop within that window after a beam is blocked; factor that into your overall safety system stopping performance calculation per ISO 13855.
Where it is used and what it includes
This class of safety light curtain is used for access guarding on machinery — think robot cells, palletizers, packaging lines, or any automated station where an operator could reach into a hazard zone. The two-beam configuration with 500 mm spacing is a common choice for perimeter guarding: it detects a person entering the area but allows smaller objects (like a box on a conveyor) to pass without tripping. The included end cap means the curtain ships with the necessary mounting bracket on one end — verify the mounting hardware matches your profile before installation. The IP65/IP67 rating means the housing and optics are sealed against washdown and temporary submersion — suitable for food processing or outdoor installations where hosing down the machine is routine. The M12 connectors on both transmitter (5-pin) and receiver (8-pin) are standard industrial quick-disconnects; you'll need mating cordsets with the correct pinout for your safety controller.
