59025-3-U-02-F Application Field and Working Principle

Magnetic sensors provide various reliable and robust sensing functions. They are often used for position, proximity, speed, or angle measurements and are a necessary component in many modern industrial, automotive, aerospace and consumer applications. The 59025-3-U-02-F module is a miniature, reed device which includes a miniature planar reed switch integrated onto a printed circuit board. It is designed to detect an external magnetic field and convert it into an electric signal. In this article, we will discuss the application field and the working principle of the 59025-3-U-02-F magnetic sensor module.

Application Field

The 59025-3-U-02-F module was designed to detect an external magnetic field and convert it into an electric signal. It is used in a variety of applications such as proximity, presence, position, speed, and angle measurement. The sensor can be used to detect both permanent and alternating magnetic fields, and is often used in absolute or limit switch applications. It is also commonly used for electronic switches in consumer, industrial, automotive and aerospace products. Examples of applications include determining the position of an object in a robotic system, detecting a motor’s rotary position, and detecting end-of-travel for limit switches.

Working Principle

The 59025-3-U-02-F module is an integrated reed device comprised of a miniature planar reed switch and a printed circuit board. The reed switch consists of two electrical contacts hermetically sealed inside an evacuated glass envelope. When the external magnetic field of sufficient strength is applied, the reed switch opens or closes. The contact opening and closing can then be used to detect the presence of a magnetic field and convert it into an electrical signal.

The module can be used in dynamic magnetic detection applications as well. By changing the position of an external magnet (or magnets), the switch will close and open proportionally depending on the magnetic field intensity and direction. The electric signal generated by the reed switch can then be used to measure speed and movement or calculate angles.

Conclusion

The 59025-3-U-02-F magnetic sensor module is designed to be used for position, proximity, speed, and angle measurements. The reed switch integrated onto the printed circuit board is used to detect an external magnetic field and convert it into an electric signal. This signal can then be used to detect the presence of a magnetic field, calculate angles and measure speed and movement. It is an important component for many modern industrial, automotive, aerospace and consumer applications.
