Encoder application classification

Encoder is a sensor that outputs digital information such as angle, length, speed and other physical quantities in the form of digital 0, 1. Because of its high precision, large range measurement, fast response, and digital output characteristics; small size, weight Lightweight, compact structure, convenient installation, simple maintenance, reliable work and other excellent characteristics, it has become a popular and indispensable part of today's industrial control system.

1) According to its measurement method, there are linear encoders and rotary encoders.

2) According to its output signal, there are incremental encoders and absolute encoders.

3) According to its internal reaction elements, there are photoelectric encoders and magnetic grid encoders.

4) It is divided into the form of mechanical mechanism, there are bearing type encoder and bearingless encoder.

Encoders can be roughly divided into commercial grade and chip grade, economic grade, standardized industrial grade, and various exceptional industrial application grades according to the usage environment.

Commercial level and chip level:

This kind of encoder is used in printers and magnetic card machines. Chip level: The price is very low, but there is no shell or a simple shell, the power supply and signal are only simply handled, and it is suitable for the manufacturer's secondary circuit development.

Economic and industrial grade:

The economical grade has simple packaging and simple disposal. It is suitable for stand-alone equipment, such as embroidery machines. However, the economical grade is characterized by its economy compared with the industrial grade. Its description and selection of materials are positioned on economical benefits, but they are not It is not suitable for large-scale equipment, assembly lines and engineering projects, and industrial-level description, material selection and testing are all done in accordance with standard industrial requirements, and suitable for various industrial equipment, assembly lines and engineering projects.
