Fargo Controls, Inc. 6.5 mm Diameter DC 3 Wire Inductive Proximity Sensor S3644

The S3644 is a 6.5 mm diameter DC 3-wire inductive proximity sensor with a stainless steel non-threaded case and flush mounting. It operates from 6 to 30 Vdc, has a switching current capacity of 200 mA, and an operating distance of 3 mm. The sensor features LED indication, short circuit and reverse polarity protection, and an IP67 protection rating. It outputs a PNP normally open signal, has a switching frequency of 2 kHz, and a repeatability of ≤3%. The power drain at 24 Vdc is less than 12 mA, with a voltage drop below 1.8 V. Operating temperature ranges from -25 to +70 °C. The output connection is a 2 meter PVC cable with a C1 connector. Hysteresis is less than 10% of the operating distance.
