Product Detail
Feature:
1. High-Precision Absolute Measurement
The time grating encoder generates a high-quality time-varying magnetic field that accurately reflects spatial position. By precisely identifying and decoding the spatiotemporal features, it achieves high-accuracy displacement measurement.
· Angular Accuracy: ±40″, ±30″, ±20″, ±10″ (without housing); ±10″, ±5″, ±2″, ±1″ (with housing)
2. High-Speed Operation
Thanks to high subdivision capability, the encoder delivers precise measurement at high speeds, making it ideal for fast-moving systems.
· Angular Speed: up to 7000 rpm (at 223/turn resolution)
3. Ultra-High Resolution
Using high-frequency time-varying magnetic fields as the sensing medium provides strong EMI resistance and high signal-to-noise ratio, enabling fine subdivisions and extremely precise displacement detection.
· Angular Resolution: 21/turn (0.0027466°), 221/turn (0.000172°), 223/turn (0.000043°)
4. Fast Response Time
The encoder offers ultra-fast signal response, with measurement signals reacting within hundreds of nanoseconds and position calculations typically completed in just a few microseconds.
· Linear/Angular Response: 5–10 μs
Highlights:
· High-Precision Time Grating Encoder – Accurate angular and displacement measurement
· High-Speed Performance – Supports up to 7000 rpm
· Ultra-High Resolution – Accuracy up to 0.000043° per turn
· Fast Response & EMI Resistant – Stable signals, measurement in 5–10 μs
· Durable & Easy Installation – Shock, vibration, and oil resistant; compact design
Application:
Time grating encoders provide high resolution, high accuracy, high repeatability, and fast-response absolute position measurement, with compact structure, oil- and dust-resistance, shock- and vibration-proof design, and easy installation. They are widely used in various industries, offering precise real-time position feedback for direct-drive and linear motors, CNC machine tool axes and accessories, automation equipment platforms and actuators, laser processing devices, testing and calibration instruments, as well as robotic joints and manipulators.
