Rotary / Angular Time Grating Encoder HTRA1-0200A

Feature:

1. High-Precision Angular Measurement
Time grating encoders generate a high-quality, time-varying magnetic field to capture precise spatial position information. By decoding the spatiotemporal features of the field, they achieve ultra-high accuracy displacement measurement.

· Angular Range: ±40″, ±30″, ±20″, ±10″ (without housing)

· With Housing: ±10″, ±5″, ±2″, ±1″

2. High-Speed Performance
Designed for high-speed applications, the encoder maintains high resolution even at rapid rotation speeds.

· Max Angular Speed: up to 7000 rpm (223/turn resolution)

· Supports fast, continuous high-speed motion monitoring in industrial and automation systems

3. High-Resolution Detection
Employs high-frequency time-varying magnetic fields for sensing, ensuring strong EMI resistance, high signal-to-noise ratio, and precise fine subdivision.

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