    Proximity Sensors

    What is a proximity sensor? A proximity sensor is a non-contact component designed to detect the presence or absence of an object without physical contact. It offers a valuable solution for working with delicate or unstable objects. Proximity sensors have key features and benefits, including motion detection of metallic and non-metallic objects, wide temperature range (-50°C to 100°C), high-speed motion sensing without contact, usability in applications with oil or water, and quicker response times compared to contactors. You can find out more on our useful guide to proximity sensors.

    There are various types of proximity sensors suitable for different applications. They operate based on a universal working principle and transmit data about object presence or motion via an electrical signal when the object is within the sensor's range. Here are some common types:

    • Infrared Sensors (IR Sensor): Infrared sensors consist of passive infrared sensors (PIR) and active infrared sensors. PIR sensors utilize pyroelectric infrared sensors in a magnetic lens, which detect changes in the signal between them. Active IR sensors employ an IR LED that emits an infrared beam to an infrared receiver, detecting obstacles that block the infrared radiation.
    • Inductive Proximity Sensors: Inductive proximity sensors generate an electromagnetic field through an oscillating circuit. Any ferrous metal object, including aluminium, copper, brass, and iron, triggers a change in the oscillation, indicating its presence.
    • Capacitive Proximity Sensors: Capacitive sensors can detect various shapes and materials, even through non-metallic walls. They are suitable for use with non-ferrous materials and find applications in close-range tasks like level detection and monitoring.
    • Ultrasonic Proximity Sensors: Ultrasonic sensors emit and receive high-frequency sound waves that can be reflected or absorbed by objects within their range. These sensors are ideal for high-speed and long-distance measurements, such as wind speed, fluid level, and speed through air or water.
    • Magnetic Proximity Sensors: Magnetic proximity sensors measure the presence or absence of an object using an external magnetic field. The sensor's reed switch is operated by a magnet, activating the sensor when the reed switch is turned ON.

    Proximity sensors are widely used in various industries and applications. They find application in automation systems, robotics, industrial manufacturing, security systems, mobile devices, and more. Proximity sensors enhance safety, efficiency, and accuracy in processes involving object detection, motion sensing, level monitoring, and presence verification.
