Linear encoders, angle encoders, and rotary encoders are types of sensors used to measure position and/or angular displacement in various applications. Here's a brief overview of where each type is commonly applied:

1. Linear Encoders:

   • Applications:
     • Machine Tools: Linear encoders are widely used in CNC (Computer Numerical Control) machine tools to provide accurate position feedback for the machine's cutting or machining operations.
     • Metrology and Inspection Equipment: Linear encoders play a crucial role in precision measurement devices such as coordinate measuring machines (CMMs) and other metrology tools.
     • Robotics: In robotic systems, linear encoders help in accurately determining the position of robot arms or actuators.
     • Printing and Paper Handling: Linear encoders are used in printers and paper handling equipment to control the precise movement of print heads or paper.

2. Angle Encoders:

   • Applications:
     • Robotics: Angle encoders are used in robotic joints to measure the angular position of the joints, providing feedback for precise control and movement.
     • Aviation and Aerospace: Angle encoders are employed in aircraft control systems to measure the orientation of control surfaces and provide feedback for navigation.
     • Medical Imaging Devices: Angle encoders are used in devices such as medical scanners to precisely position and control the movement of imaging components.

3. Rotary Encoders:

   • Applications:
     • Motor Feedback Systems: Rotary encoders are commonly used in motor feedback systems to provide information about the rotor's position, speed, and direction, facilitating closed-loop control.
     • Automotive: In vehicles, rotary encoders are used in applications like steering angle sensing, throttle position sensing, and gearbox position sensing.
     • Consumer Electronics: Rotary encoders can be found in various consumer electronics devices, such as audio equipment (volume control), computer mice, and user interface controls.
     • Automation and Industrial Control: Rotary encoders are utilized in various industrial automation applications, providing feedback for position control in conveyor systems, indexing tables, and more.

In summary, these types of encoders find application in a wide range of industries, including manufacturing, robotics, aerospace, automotive, and medical fields, where precise position and angular displacement measurements are critical for control and operation.
