Fargo Controls, Inc. 30 mm Diameter DC 4 Wire Capacitive Sensor S5101

The S5101 is a 30 mm diameter capacitive sensor with a threaded M30 x 1.5 housing, designed for non-contact detection with an adjustable sensing range of 0-20 mm. It operates on a 10-60 Vdc power supply, draws ≤10 mA at 24 Vdc, and handles a maximum switching current of 200 mA with a voltage drop of less than 1.8 V when ON. The sensor provides PNP normally open and normally closed outputs, features short circuit and reverse polarity protection, and includes an LED indicator. It is rated IP67 for dust tightness and immersion protection, operates from -20 to +70 °C, and uses a 3 m PVC cable with a right-angle or straight connector option. Flush mounting is supported. Repeatability is less than 10% of Sn, and hysteresis is ≤20% of Sn dependent on sensing distance. The case is made of nickel-plated brass.
