Working Principle

Magnetic Field Variation: The magnetic ring is segmented into multiple magnetic poles arranged in a specific sequence. As the ring rotates, the sensor detects changes in the magnetic field strength.
Signal Conversion: The sensor converts the detected magnetic field variations into electrical signals, which are then processed to obtain precise rotational angle, speed, and direction information.

Characteristics of Radial Single-Track Encoders

Simple Structure: Compared to other types of encoders, radial single-track encoders have a relatively simple structure, making them easy to install.
High Precision: Through optimized design and manufacturing processes, high angular resolution can be achieved.
High Reliability: Due to the absence of mechanical contact, they offer high reliability and are less prone to wear.
Strong Anti-interference Capability: They exhibit strong resistance to environmental factors such as dust and oil.

Applications of Radial Single-Track Encoders

Radial single-track encoders are widely used in various automation equipment, including:
Motor Control Systems: For precise control of motor speed and position.
Robotics: For controlling the joint movements of robots.
Numerical Control Machine Tools: For precise control of machine tool movements.
Automated Production Lines: For monitoring and controlling the operation of production lines.

Comparison with Other Types of Encoders

Radial Single-Track Encoder: The magnetic field is perpendicular to the axis, with a simple structure and lower cost.
Axial Single-Track Encoder: The magnetic field is parallel to the axis, offering higher precision but with a relatively complex structure.
Optical Encoder: It utilizes optical principles to measure angles, providing high precision but is susceptible to environmental influences.
