Learn about the different types of proximity sensors, how they work, and where they are used. Compare inductive, capacitive, ultrasonic, IR, and high-end proximity sensors and their advantages and disadvantages. This blog covers the basics of proximity sensors , its working, applications, and advantages and disadvantages. What are Proximity sensors ? Overview A proximity sensor is a non-contact sensor that detects the presence of an object (also known as the “target”) when it enters the sensor ’s field of view. The sensor may detect a target via sound, light, infrared radiation (IR), or electromagnetic fields, depending on the type of proximity sensor . Phones, recycling factories, self-driving ... Types of Proximity sensors are inductive proximity sensor , Optical, Capacitive, Magnetic and Ultrasonic proximity sensors . A proximity sensor (often simply prox) is a sensor able to detect the presence of nearby objects without any physical contact. A proximity sensor often emits an electromagnetic field or a beam of electromagnetic radiation (infrared, for instance), and looks for changes in the field or return signal.
