Rotary / Angular Time Grating Encoder HTRA3-0170A

Feature:

1. High-Precision Time Grating Encoder

The time grating encoder generates a high-quality time-varying magnetic field to detect angular and linear positions with extreme accuracy. By precisely decoding 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 Absolute Position Measurement

Supports high-speed operation with fine subdivision, allowing precise angular measurement up to 7000 rpm. Even at high speed, the encoder maintains high-resolution output.

Angular Subdivision: 223/turn resolution

3. High-Resolution and EMI-Resistant Encoder

Uses high-frequency time-varying magnetic fields as the sensing medium, providing strong EMI resistance, high signal-to-noise ratio, and ultra-fine subdivision for precise displacement detection.

Angular Resolution Options: 21/turn (0.0027466°), 221/turn (0.000172°), 223/turn (0.000043°)

4. Ultra-Fast Responsiveness

The encoder delivers rapid response with measurement signals reacting within hundreds of nanoseconds. Position calculations are completed in just a few microseconds, ensuring real-time tracking of linear and angular movements.

Linear/Angular Response Time: 5–10 μs

Highlights:

· High-Precision Measurement – Accurate linear and angular displacement with time-grating technology.

· Wide Accuracy Range – ±40″ to ±1″ depending on housing.

· High-Speed Operation – Supports up to 7000 rpm while maintaining resolution.

· Ultra-High Resolution & EMI-Resistant – Fine subdivision with 21/turn, 221/turn, 223/turn and strong interference resistance.

· Fast Response & Robust Design – Signals react within 5–10 μs, with oil-resistant, shock- and vibration-proof structure.

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.
