Product Description

The INT-F50S Fiber Optic Gyroscope (FOG) is a high-performance angular rate sensor based on the Sagnac optical effect, utilizing all-digital closed-loop detection technology. It delivers real-time angular velocity output exceeding 4 kHz via a serial interface. The series includes single-axis, dual-axis, and three-axis configurations, with multi-axis variants sharing a common light source and processing circuitry for synchronous orthogonal axis measurement.

Applications:

  • Guidance systems and tactical missiles

  • Attitude control and stabilization platforms

  • Torpedoes and naval systems

  • Industrial stabilization and precision equipment

Key Features:

  1. Compact, lightweight, and modular design for easy integration

  2. All-solid-state construction with no moving parts

  3. Instant startup with digital interface for rapid deployment

  4. Low noise, low power consumption, and cost-efficient operation

  5. High reliability with extended operational lifespan
