Tips: What is a magnetic speed sensor?
A magnetic speed sensor, also known as a magnetic pickup or magnetic encoder, is a device used to measure the speed or rotational velocity of a moving object. It operates based on the principle of magnetic induction.
The sensor consists of a magnet and a coil, often referred to as a magnetic pickup coil or a Hall effect sensor. When the object being measured has a magnetic target or features, such as a toothed wheel or a magnetized shaft, the magnetic sensor can detect changes in the magnetic field as the object moves.
As the target passes by the sensor, the magnetic field strength fluctuates, inducing a voltage or current in the coil. This variation in voltage or current corresponds to the speed or rotational velocity of the object. The sensor then converts this electrical signal into a readable output, such as a frequency, pulse, or analog signal, which can be used by other devices for further processing or control.
Magnetic speed sensors are commonly used in various applications, including automotive systems, industrial machinery, robotics, and aerospace. They provide a non-contact method for measuring speed and are often preferred in environments where contact-based sensors may be prone to wear or damage.
