Proximity Sensor

More Information

A proximity sensor is a device that detects the presence of nearby objects without physical contact. It works by emitting a signal, such as an electromagnetic field or electromagnetic radiation, and monitoring for changes in that signal when an object enters the sensing zone. These sensors are widely used in various applications, including industrial automation, robotics, and mobile devices.

Here's a more detailed explanation:
1.Non-contact Detection: Proximity sensors are designed to avoid physical contact with the object they are detecting, making them suitable for delicate objects or situations where contact might be detrimental.
2.Signal Emission and Reception: They typically send out a signal, which could be an electromagnetic field, ultrasonic waves, or infrared light, and then detect changes in the signal's return or field as an object approaches or enters the sensor's range.
