Fargo Controls, Inc. Rectangular DC 3 Wire Inductive Proximity Sensor S3166

The S3166 is a rectangular DC 3-wire inductive proximity sensor with PNP normally open output, designed for non-contact detection of metallic objects. It features short circuit and reverse polarity protection, an LED function indicator, and an IP67 protection rating for dust tightness and immersion resistance. The sensor operates on a 6-30 Vdc supply, has a 2 mm operating distance, a maximum switching current of 200 mA, and a voltage drop of less than 1.8 V when ON. It supports an operating frequency of 1 kHz, with repeatability within ±3% of the rated distance and hysteresis under 10%. The case is made of anodized aluminum with flush mounting capability. Output connection is via a 2-meter PVC cable, with 3.5, 5, 7.5, and 10 meter cable lengths available upon request. The operating temperature range is -25 to +70 °C, with a +100 °C high-temperature version available on request.
