Fargo Controls, Inc. 6.5 mm Diameter DC 3 Wire Inductive Proximity Sensor S3640

S3640 is a 6.5 mm diameter, non-threaded, stainless steel inductive proximity sensor with a 3-wire DC output, designed for non-flush mounting with a 2 mm operating distance. It features NPN normally open output, LED status indication, short circuit and reverse polarity protection, and an IP67 rating for dust and water immersion resistance. The sensor operates on 6-30 Vdc, draws less than 12 mA at 24 Vdc, and switches up to 200 mA with a switching frequency of 2 kHz. Repeatability is within ±3% of the rated operating distance, and hysteresis is less than 10%. The output connection is a 2-meter PVC cable with a C1 connector. Operating temperature ranges from -25 °C to +70 °C.
