Product Detail
Feature:
1. High-Precision Measurement
Our time grating encoders generate a high-quality, time-varying magnetic field to capture precise spatial position information. By decoding spatiotemporal features, they achieve ultra-accurate displacement measurements.
· Angular Accuracy (without housing): ±40″, ±30″, ±20″, ±10″
· Angular Accuracy (with housing): ±10″, ±5″, ±2″, ±1″
2. High-Speed Performance
Supports high-resolution measurement even at high speeds thanks to advanced subdivision technology.
· Maximum Angular Speed: up to 7000 rpm (at 223/turn resolution)
3. Ultra-High Resolution
Uses high-frequency time-varying magnetic fields as the sensing medium for excellent EMI resistance and high signal-to-noise ratio. Ensures fine subdivision for precise displacement detection.
· Angular Resolution Options: 21/turn (0.0027466°), 221/turn (0.000172°), 223/turn (0.000043°)
4. Fast Response Time
Provides ultra-fast response signals with measurements reacting within hundreds of nanoseconds. Position calculation is typically completed in a few microseconds.
· Linear/Angular Response: 5–10 μs
5. Reliable & Durable (SEO-friendly extra feature)
Designed for industrial environments, resistant to shock, vibration, and oil contamination, ensuring stable performance in demanding applications.
Highlights:
· Ultra-High Precision – Achieves micron-level displacement measurement for angular and rotary applications.
· High-Speed Operation – Supports angular speeds up to 7000 rpm without losing accuracy.
· Exceptional Resolution – Fine subdivisions down to 0.000043° for precise motion control.
· Rapid Response – Position signals processed within microseconds for real-time applications.
· Robust Industrial Design – Resistant to shock, vibration, and oil, ensuring reliable performance in harsh environments.
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.
