The S4393 is a fork-shaped, DC-powered photoelectric sensor with a nickel-plated brass case, designed to detect non-transparent and translucent materials. It features a 13 mm fork gap, infrared light source, and operates on a 10-30 Vdc supply with a maximum switching current of 200 mA. The sensor has a voltage drop of less than 1.5 V at 200 mA, a power drain of less than 15 mA at 24 Vdc, and an operating frequency of up to 500 Hz. It includes short circuit and reverse polarity protection, an LED function indicator, sensitivity adjustment, and conforms to IP67 for dust tightness and water immersion resistance. The output is PNP normally closed, with a 2 meter PVC cable connection. Operating temperature ranges from -25 °C to +50 °C. Light immunity is rated for sunlight up to 10,000 Lux and incandescent lamps up to 3,000 Lux.
