Basic knowledge of Linear Encoders:
What is an Linear Encoder?

A linear encoder is a measuring device used to determine the position or displacement of an object in a linear motion. It typically consists of a scale and a readhead that detects the position on the scale.

How does a linear encoder work?

Linear encoders work based on different principles, such as optical, magnetic, or inductive. The scale contains a periodic pattern, and the readhead detects the changes in the pattern as it moves along the scale. These changes are converted into electrical signals that represent the position.

What are the Advantages of Linear Encoders?

Linear encoders offer high precision and accuracy in position measurement. They provide real-time feedback and enable closed-loop control systems. They are non-contact devices, which means they have no mechanical wear or backlash. They are also immune to environmental factors like dust, temperature, and humidity.

What are the types of linear encoders?

Linear encoders can be categorized into several types based on their operating principles, including optical linear encoders, magnetic linear encoders, and inductive linear encoders.

Linear Encoder Type Advantages
Optical Linear Encoder - High resolution and accuracy
  - Excellent repeatability and linearity
  - Immunity to electromagnetic interference (EMI)
  - Wide temperature operating range
  - Suitable for high-speed and dynamic applications
Magnetic Linear Encoder - Robust design, resistant to dust and contaminants
  - High durability and reliability
  - Can operate in harsh environments
  - Cost-effective compared to optical encoders
Inductive Linear Encoder - Suitable for harsh industrial environments
  - Resistant to contaminants, oil, and fluids
  - High resistance to vibration and shock
  - Long operating life with minimal maintenance
  - Can operate in high temperatures

Based on the application environment, the linear encoders can also be divided into open/exposed linear encoders and close/unexposed linear encoders:

Linear Encoder Configuration Description
Open Linear Encoder The scale (or tape) is exposed and visible, mounted on one part of a system.
  - Allows easy inspection, maintenance, and cleaning of the scale.
  - Suitable for applications where accessibility and maintenance are important.
Closed Linear Encoder The scale and readhead are enclosed within a protective housing.
  - Provides protection against contaminants like dust, debris, and liquids.
  - Ideal for applications in harsh environments or where contamination must be prevented.
What Parameters are needed to choose a Linear Encoder?

To choose the right angle encoder for your application, several parameters should be considered. These parameters include:
Resolution, Encoder Type, Repeatability, Accuracy, Interface Protocol, Environmental Considerations, Shaft Size and Mounting, Electrical Supply, Cost.
