Fargo Controls, Inc. 5 mm Diameter Inductive Sensor with Increased Sensing Distance S3903

The S3903 is a 5 mm diameter inductive sensor with an extended operating distance of 1.5 mm, designed for DC 3-wire applications. It features a stainless steel case, flush mounting, IP67 protection, an LED function indicator, and short circuit and reverse polarity protection. The sensor operates on 10-30 Vdc, has a maximum switching current of 200 mA, a voltage drop of less than 1.5 V when on, and an operating frequency of 2 kHz. Repeatability is within ±1% of the rated sensing distance, and hysteresis is less than 15%. The operating temperature range is -25 to +70 °C, and the output connection is a 2 m pigtail cable with a C1 connector.
