One,Single-turn encoderOverview

The working principle of a single-turn encoder involves converting the position of a rotating shaft into electrical signals, which are then processed electronically to output corresponding digital or pulse signals. Key features include:

• High-precision measurementAchieves angular resolution of 0.1° or even higher
• Real-time feedbackProvide stable rotational angle information for the control system.
• Multiple output methodsIncremental output or absolute value encoding output
• Widely applicableIndustrial automation, robotics, multi-axis machinery, and precision equipment

Compared to multi-turn encoders, single-turn encoders are suitable for applications with limited rotation ranges but high precision requirements, providing reliable, real-time position data.
