Fargo Controls, Inc. Rectangular DC 3 Wire Inductive Proximity Sensor S3161

The S3161 is a rectangular DC 3-wire inductive proximity sensor with NPN normally closed output, designed for industrial sensing applications. It features short circuit and reverse polarity protection, an LED function indicator, and an IP67-rated case for dust-tight and water-immersion resistance. The sensor has an operating distance of 2 mm, operates on a 6-30 Vdc power supply, and switches up to 200 mA with a voltage drop of less than 1.8 V when ON. It supports a maximum operating frequency of 1 kHz and has a repeatability of ≤3% and hysteresis of <10%. The case is made of anodized aluminum for flush mounting, with a 2 m PVC cable output. An optional high-temperature version up to +100 °C is available upon request.
