2wire Inductive Sensor Arduino

The sensor is a NAMUR 2 wire inductive pickup NJ1.5-8GM-N by Pepperl Fuchs used to count the teeth on a steel pulley as it goes around pretty slowly something like 10rpm. I am trying to figure out how to use an arduino to measure this sensor's output.

Inductive sensors are devices that measure the change in magnetic flux around a coil or core. This flux is translated into electrical signals that represent the speed, direction and proximity of the target object. What Is A 2 Wire Sensor Working Principles Of Two Sensors. Wiring A Metal Detector With Npn Proximity Sensor On Arduino

Put a 510 Ohm resistor in series with the sensor ground lead, and use either a digital or an analog input to monitor the voltage drop. Expect about 1V and 4V respectively. It is a good idea to add a 10K series resistor to protect the Arduino input from overvoltage. The Arduino ground and sensor ground must be connected together.

The 10 k resistor limits the current into the pin of the arduino. If your arduino is running at 5V and the sensor is at 9V without the 10k you would quotpowerquot the arduino through the input protection circuit causing it to fail. The 10 k limits the current into the arduino input pin to 9-510k 0.4 ma , well within the specifications of the AVR

Inductive sensors can be available in both ac and dc supply operated. Some inductive sensor consists of 2 wires while some consists of three to four wires. It can be available in various shapes such as tubular, rectangular and ring shaped. Inductive sensor can detect a target from 0.5 millimeters to 40 millimeters.

Inductive proximity sensors are indispensable tools in various industries, such as automation, automotive, and manufacturing, due to their ability to detect the presence of metallic objects without physical contact. Among the different types of these sensors, two-wire inductive proximity sensors are particularly popular for their simplicity and ease of installation.

Two Wire Sensor. Difference between 2-wire and 3-wire technology. What exactly is the difference between the 4-20 mA output signal in 2- and 3-wire technology? This question is answered best from the viewpoint of the user An output signal in 2-wire technology means less wiring required
