The Omron F3SG4PGA10704C is a Type 4 safety light curtain from the F3SG-PG series, built for perimeter and access guarding where a 1,070 mm protected height covers a standard doorway or machine opening. Four beams at 300 mm spacing means finger and hand detection through the plane — the 300 mm gap catches a reaching arm before it enters the hazard zone, not individual digits. The 870 nm IR LED emitter and receiver pair are matched; the 5 m sensing range covers most cell entries without needing a mirror or deflection. Rated for 24V DC power, the safety outputs source up to 300 mA each — enough to drive a safety relay or safety PLC input directly, no interposing relay needed for most control circuits. The auxiliary output is NPN and PNP configurable at 100 mA, useful for feeding a status lamp or a non-safe PLC diagnostic input. Response time is 8 ms maximum, which keeps the stopping distance calculation within a reasonable safety distance for most machine speeds. Both ends terminate in M12 connectors — 5-pin on the transmitter, 8-pin on the receiver. That is the standard industrial quick-connect format; no hardwiring through a gland plate. The end caps are included in the box, so alignment and mounting hardware are covered without a separate kit order.
IP65 and IP67 rated means the housing and optics survive washdown — suitable for food processing lines or outdoor conveyor gantries where a hose-down is part of the cleaning cycle. The operating range spans -22 °F to 131 °F, which covers most indoor plant floors and unheated warehouses. CE, CSA, and UL Listed marks are on record. That clears the part for installation in North American and European machinery without a separate agency review. No AC rating — this is a DC-only safety device, so confirm your control voltage is 24V nominal before wiring.
