Fargo Controls, Inc. 4 mm Diameter DC 3 Wire Inductive Proximity Sensor S3517

The S3517 is a 4 mm diameter, three-wire inductive proximity sensor with a stainless steel non-threaded case and flush mounting capability. It operates on a 6 to 30 Vdc power supply, with a maximum switching current of 150 mA and a power drain of less than 10 mA at 24 Vdc. The sensor has a switching distance of 0.8 mm, a repeatability of ≤3% of the sensing distance, and hysteresis of less than 10%. It features an LED function indicator, short circuit and reverse polarity protection, and an IP67 rating for dust tightness and immersion resistance. The output is PNP with normally closed function, and it includes a 2 meter cable with a C1 connector. Operating temperature ranges from -25 to +70 °C, and the switching frequency is 2 kHz.
