Rotary / Angular Time Grating Encoder HTRA3-0035B

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
