A synchronous encoder is a high-precision position and speed detection device that achieves closed-loop control of motion systems by real-time capturing angular displacement signals of rotating components and converting them into electrical signals. It is widely used in industrial automation, robotics, CNC machine tools, and other fields to ensure operational stability and positioning accuracy of equipment.

Working Principle

Signal Acquisition: Scans the scale of the encoder disc (or magnetic ring) through photoelectric induction (or magnetoelectric induction) to generate periodic pulse signals.
- Synchronous Output: Output signals are strictly synchronized with the motion state of the motor or rotating shaft. Common output types include:
  - Incremental (A/B phase pulses, Z phase zero position signal)
  - Absolute (multi-turn encoding, directly outputs absolute position values)
  - Signal Processing: Pulse signals are amplified and shaped before being transmitted to the controller for position feedback and speed adjustment.

Key Technical Parameters

Parameter Type	Description
Resolution	Common range: 100–5000 PPR (Pulses Per Revolution), supports customized high resolution (e.g., 10000 PPR).
Output Signal	TTL, HTL, RS422, sine wave (Sin/Cos), etc., compatible with mainstream controller interfaces.
Operating Voltage	DC 5V, DC 12–24V (optional by model), with strong resistance to power fluctuations.
Maximum Speed	Typically ≤6000 RPM; high-speed models reach 10000 RPM, adapting to different working conditions.
Protection Class	Housing with IP54/IP65 protection, dust and liquid splash-proof, suitable for harsh industrial environments.

Application Fields

Industrial Automation: Servo motor control, production line drive systems, robotic arm positioning.
CNC Machine Tools: Position feedback for main shafts and feed shafts to ensure machining accuracy.
Robotics: Joint motion detection for precise trajectory control.
New Energy Equipment: Wind turbine pitch control, solar tracking systems.
Aerospace: Flight attitude sensors, precision pan-tilt adjustment.

Product Advantages

High-Precision Feedback: Adjustable resolution, positioning error ≤±1 pulse, meeting micron-level control requirements.
Anti-Interference Design: Built-in shielding layer and differential signal output effectively suppress electromagnetic interference (EMI).
Long Service Life: Metal encoder shaft and wear-resistant bearings ensure mean time between failures (MTBF) ≥30,000 hours.
Flexible Adaptation: Supports multiple installation methods (flange type, bushing type) for compatibility with different mechanical structures.
Real-Time Synchronization: Signal delay ≤1ms ensures dynamic response and system synchronization.

Structure and Materials

Housing: Aluminum alloy/stainless steel with anti-oxidation treatment for strong corrosion resistance.
Code Disc: Glass disc (high-precision models) or metal disc (impact-resistant models), with line engraving accuracy ±5μm.
Interface: Aviation plug or cable outlet, supports customized waterproof connectors.

Selection Recommendations

For dynamic high-speed response, recommend incremental + sine wave output models.
For power-off position memory, recommend absolute multi-turn encoders (e.g., 17-bit, 23-bit encoding).
In harsh environments (high temperature, dust), suggest magnetoelectric encoders (no optical components, strong anti-pollution capability).
