Rotary / Angular Time Grating Encoder HTRA3-0128A

Feature:

1. High Precision Rotary / Angular Encoder
Time grating encoders generate a stable, time-varying magnetic field that directly reflects spatial position. By accurately decoding this signal, the encoder achieves high-precision displacement measurement.
Accuracy Options: ±40″, ±30″, ±20″, ±10″ (without housing) | ±10″, ±5″, ±2″, ±1″ (with housing). Ideal for CNC machines, robotics, and precision positioning systems.

2. High Speed Performance
With advanced subdivision technology, the encoder ensures high-resolution measurement at ultra-high speeds.
Angular Speed: up to 7000 rpm (at 2²³/turn resolution). Perfect for applications requiring fast rotary feedback and reliable angular measurement.

3. High Resolution Measurement
Using high-frequency magnetic fields as the sensing medium, this time grating encoder offers excellent EMI resistance and a superior signal-to-noise ratio. This enables fine subdivision and ultra-precise position detection.
Resolution: 2¹¹/turn (0.0027466°), 2²¹/turn (0.000172°), 2²³/turn (0.000043°).

4. High Responsiveness
Designed for real-time feedback and fast control, the encoder delivers an ultra-fast response.
Response Time: Signal reacts within hundreds of nanoseconds; position calculation completed in 5–10 μs. Suitable for servo drives, motion control, and automation systems.
