Research and Application of Rotary Encoder Mouser

Abstract

Rotary Encoder (REC) is a commonly used sensor that converts rotary motion into electrical signals. This paper focuses on the rotary encoder products provided by Mouser, including its working principle, main application areas, and key points for purchase.

I. Introduction

With the continuous development of science and technology, rotary encoders have been widely used in many fields, such as industrial automation, robotics, automotive, aerospace and so on. As a world-renowned electronic components supplier, Mouser provides engineers and manufacturers with a wealth of rotary encoder products. The purpose of this article is to provide a detailed introduction to these products to help users better understand and use rotary encoders.

Second, the working principle of rotary encoder

A rotary encoder is a sensor that converts rotary motion into an electrical signal. It is mainly composed of a rotor, a coding disc, a photoelectric detector and a circuit. When the rotor rotates, the grating lines on the coding disc will cut the light emitted by the photoelectric detector, thus generating pulse signals. These pulse signals are processed by the circuit to obtain parameters such as rotation angle and speed.

Third, Mouser rotary encoder product introduction

Mouser offers a wide range of rotary encoders, including incremental rotary encoders, absolute rotary encoders, and high-precision rotary encoders. These products have different resolutions, output signal types, operating temperature ranges and other characteristics to meet the needs of various application scenarios.

1. Incremental Rotary Encoders

Incremental rotary encoders output pulse signals, and the angle of rotation can be obtained by counting the number of pulses. This type of encoder has the advantages of simple structure and low price, and is widely used in industrial automation, robotics and other fields.

2. Absolute Rotary Encoders

Absolute rotary encoders have a unique code for each position, so the position of the rotor can be accurately known. This type of encoder has the advantages of strong anti-interference ability, high accuracy, etc. It is suitable for demanding application scenarios, such as aerospace, automotive and other industries.

3. High-precision rotary encoders

High-precision rotary encoder has the characteristics of high resolution, low error, etc., which is suitable for the application scenarios with very high requirements on precision, such as precision instruments, scientific research and other fields.

Fourth, the main application areas of rotary encoders

1. Industrial automation: rotary encoders are widely used in industrial automation, such as motor speed control, production line conveyor belt speed detection, etc.

2. Robotics: rotary encoders are used in the field of robotics to measure the joint angle, speed and other parameters to achieve precise control.

3. automotive: rotary encoders are used in the automotive industry for abs antilock systems, electric power steering systems, etc.

4. aerospace: rotary encoder in the aerospace field for measuring the attitude of the aircraft, speed and other parameters.

Fifth, the main points of the purchase of rotary encoders

1. resolution: according to the application requirements to choose the appropriate resolution to meet the accuracy requirements.

2. output signal type: according to the requirements of the control system to select the appropriate output signal type, such as analogue signals, digital signals, etc..

3. operating temperature range: select the appropriate operating temperature range according to the actual application environment.
