Fargo Controls, Inc. Rectangular DC 4 Wire Inductive Proximity Sensor S3157

The S3157 is a rectangular, 4-wire DC inductive proximity sensor with PNP, NO+NC output, featuring an adjustable operating distance from 10 to 60 mm, short circuit and reverse polarity protection, and an LED function indicator. It operates on a 10-55 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 less than 10 mA at 24 Vdc. The sensor has an operating frequency of 50 Hz, repeatability of ≤ 3%, and hysteresis of less than 10% at 50 mm sensing distance. It is housed in a plastic case, is not flush-mountable, has an IP65 protection rating, and uses a connector (C2) with a mating screw-terminal connector included. Operating temperature ranges from -25 to 70 °C.
