Proximity Sensor

A proximity sensor is a type of sensor that detects the presence or absence of nearby objects without physical contact. Proximity sensors are commonly used in industrial and manufacturing settings to automate processes, improve safety, and reduce downtime.There are several types of proximity sensors, including inductive, capacitive, ultrasonic, and magnetic sensors. Inductive proximity sensors use an electromagnetic field to detect the presence of metallic objects, while capacitive sensors use changes in capacitance to detect the presence of any object, including non-metallic objects. Ultrasonic sensors use sound waves to detect objects, while magnetic sensors use magnetic fields to detect metallic objects.
