Integrator's field note
The Omron F3SG4PGA13704C is a 4-beam safety light curtain from the F3SG-PG series, with 400 mm beam spacing and a protected height of 1,370 mm. It runs on 24V DC and uses 870 nm IR LEDs. The safety outputs are rated 300 mA at 24V DC, and the auxiliary output is NPN/PNP configurable at 100 mA. Response time is 8 ms maximum, and the sensing range goes to 5 m. IP65/IP67 means the housing and optics handle washdown environments — suitable for food, beverage, or wet machining lines. CE, CSA, and UL Listed approvals cover North American and European installations.
The transmitter uses a 5-pin M12 connector; the receiver uses an 8-pin M12. End caps are included in the box — no extra hardware needed for the basic pair. Overall height is 53.94 inches, depth 1.5 inches, width 1.84 inches. The 400 mm beam spacing means the 4 beams cover a 1,370 mm protected zone with gaps between beams — not finger-safe, but suitable for body or limb detection per IEC 61496.
