The S5111 is a 30 mm diameter DC 4-wire capacitive sensor with a nickel-plated brass case, flush mounting capability, and an adjustable operating distance of 0-20 mm. It operates on a 10-60 Vdc power supply with a maximum switching current of 200 mA, a voltage drop under 1.8 V when ON, and a power drain of no more than 10 mA at 24 Vdc. The sensor has an IP67 protection rating, operates between -20 to +70 °C, and includes short circuit and reverse polarity protection. Its output is PNP with normally open and normally closed contacts, and it features an LED function indicator with a 3 m PVC cable connection. Operating frequency is 10 Hz, repeatability is less than 10% of Sn, and hysteresis is up to 20% of Sn.
