Fargo Controls, Inc. Rectangular DC 3/4 & AC 2 Wire Inductive Proximity Sensor S3168

The S3168 is a DC 3-wire inductive proximity sensor with NPN normally open and normally closed outputs, designed for industrial positioning and detection tasks. It features short circuit and reverse polarity protection, an LED function indicator, and an IP67 protection rating for dust-tight and immersion-resistant operation. The sensor operates on a 10-30 Vdc power supply with a maximum switching current of 200 mA, a voltage drop of less than 1.8 V when ON, and a power drain below 15 mA at 24 Vdc. It has an operating frequency of 1 kHz, repeatability of ≤3% of Sn, and hysteresis of less than 10%. The case is plastic, with non-flush mounting, and it includes a 2-meter PVC cable output. An optional high-temperature version up to +100°C is available upon request.
