Fargo Controls, Inc. 5 mm Diameter Inductive Sensor with Increased Sensing Distance S3904

The S3904 is a 5 mm diameter inductive sensor with an extended operating distance of 1.5 mm, designed for DC 3-wire applications. It features a stainless steel case, flush mounting capability, and an IP67 protection rating for dust tightness and immersion resistance. The sensor operates on a 10 to 30 Vdc power supply, has a maximum switching current of 200 mA, and a voltage drop of less than 1.5 V when active. It includes an LED function indicator, short circuit and reverse polarity protection, and a 2-meter cable with a C1 pigtail connector. Operating frequency is 2 kHz, with repeatability within ±1% of the rated distance and hysteresis under 15%. The operating temperature range is -25 to +70 °C.
