Proximity Sensors

Proximity sensors are devices used to detect the presence or absence of objects without physical contact. They operate on various principles such as infrared, ultrasonic, capacitive, or inductive detection methods. Infrared sensors measure distance using light, while ultrasonic sensors use sound waves. Capacitive sensors detect changes in electrical fields, and inductive sensors identify metallic objects through electromagnetic induction. These sensors are crucial in various applications, including manufacturing automation, robotics, and vehicle safety systems, where they help in object detection, collision avoidance, and precise positioning. Their non-contact nature ensures durability and reliability, making them ideal for harsh environments or delicate surfaces.
