Link to M18 Size Proximity Sensor A proximity sensor is a non-contact sensor that detects the presence of an object (often referred to as the “target”) when the target enters the sensor’s field. Depending on the type , sound, light, infrared radiation (IR), or electromagnetic fields may be utilized by the sensor to detect a target. They are used in phones, recycling plants, self-driving cars, anti-aircraft systems, and assembly lines. There are many types of  sensors, and they each sense targets in distinct ways. The two most commonly used proximity sensors are the inductive sensor and the capacitive sensor. An inductive sensor can only detect metal targets. This is because the sensor utilizes an electromagnetic field. When a metal target enters the electromagnetic field, the inductive characteristics of the metal change the field’s properties, thereby alerting the sensor of the presence of a metallic target. Depending on how inductive the metal is, the target can be detected at either a greater or shorter distance. Type of models available:- PNP NO PNP NC NPN NO NPN NC AC NO AC NC
