The characteristics of Magnetic Encoder can be summarized in the following aspects:
Principle and design:
Magnetic encoders obtain position information by detecting changes in the magnetic field and convert it into an electrical output. It uses a magnetoresistive or Hall element to measure the Angle or displacement value of a changing magnetic material.
The magnetic encoder adopts magnetoelectric design, and the absolute position of the rotor is generated and provided by the magnetic induction device using the change of the magnetic field, thus realizing the simple detection structure without complex code disk and light source.
Environmental adaptability:
Magnetic encoders have strong environmental adaptability, are not affected by dust, moisture and other pollutants, and are especially suitable for harsh environment and pollutant applications.
Compared with the traditional photoelectric encoder and grating encoder, the magnetic encoder has the characteristics of anti-vibration, anti-corrosion, anti-pollution, anti-interference and wide temperature, and can be applied to the fields that the traditional photoelectric encoder can not adapt to.
Physical characteristics:
Magnetic encoder has the characteristics of small size, light weight, compact structure, easy to install and maintain.
Its small and lightweight design makes it more widely used in the field of automation control.
Performance characteristics:
Magnetic encoder has the characteristics of high frequency sound, high resolution, low power consumption, stable and reliable performance, long service life and so on.
It can achieve resolutions as low as 1 micron, meeting the high precision requirements of industrial measurement and control.
Magnetic encoder adopts contactless design, simple and compact structure, long life, high and low temperature resistance, vibration resistance, fast response speed.
Application field:
Magnetic encoders are widely used in motor, elevator, CNC machine tools, robots and other automation control fields.
It can be used for precise control of servo motors and stepper motors, as well as for motion and position control of robotic articulated robotic arms.
In PLC applications, magnetic encoders can be used as high-speed signal input components to enable PLC to implement closed-loop control more quickly and accurately.
Signal output:
The signal output form of the magnetic encoder is a digital pulse signal, which can be rotated at high speed and has fast response speed.
In summary, magnetic encoders have become an indispensable part of industrial automation and motion control with their unique principle design, strong environmental adaptability, excellent physical and performance characteristics, and a wide range of application fields.
