Rotary Encoders
Rotary encoders are electro-mechanical devices or sensors designed to output digital or analogue signals by detecting and converting the angular position or motion of a shaft or axles. The output signals––which when analysed using microcontrollers or other digital systems––determine the precise speed, position, and direction of the shaft. A typical rotary encoder is mounted into the motor's or shaft's assembly (using rotary encoder mounting brackets) that effectively translates their mechanical position to electrical signals. Rotary encoders are known for their high resolution, durability, robust precision, and versatility, making them perfect for applications requiring precise control, monitoring, and feedback of rotary motion.
Common Types of Rotary Encoders:
Rotary encoders come in the following main types, such as:
- Mechanical Rotary Encoders – These encoders use mechanical components like springs, detents, and brushes to detect rotation. A typical setup includes a rotating disc with slots or ridges, and sensors detect changes as these elements move.
- Optical Rotary Encoders – Optical rotary encoders use light and sensors to detect changes in position. They typically have a light source, a disc with opaque and transparent segments, and sensors to detect the light passing through the disc.
Typical Applications of Rotary Encoders:
Rotary encoders are widely used in multiple industries and applications, including:
- Industrial Automation
- Robotics
- Automotive Systems
- CNC Machines
- Camera Controls
- Consumer Electronics
- Medical Devices.
