FLUX uses Giant Magneto Impedance (GMI) technology for encoders, setting new standards for precision and adaptability in a wide range of applications. GMI technology is a principle that has been around for a long time, but is now being used in a way that is transforming encoder technology. The GMI effect involves the change in impedance of a material when exposed to an external magnetic field, which can then be used to measure rotational or linear motion with unprecedented accuracy.

FLUX's GMI encoders exploit this principle to deliver performance beyond the limits of traditional sensors. Their advanced design makes them ideal for machine tools, gyro-stabilised platforms and high-performance test benches.

Encoder Portfolio

FLUX has 2 main product lines using GMI technology: 
GMI® Angle Encoders (GMI-ANG Series) provide ultra-fast and accurate angle measurements in arc seconds, making them perfect for demanding applications where high standards are required.
GMI® Rotary Encoders (GMI-ROT Series) offer the benefits of GMI technology in a compact space, solving challenges where traditional encoders fall short.

Applications that benefit 

Machine tools: GMI angle encoders feature a bearingless design that eliminates the wear problems associated with conventional encoders. They offer real-time data acquisition with angular accuracy of ±4 arc seconds, ensuring optimum performance even in harsh environments.

Gyro-stabilised platforms: Used in cameras and optical devices, these platforms require encoders that can withstand vibration and temperature extremes. GMI encoders meet these requirements with their compact design, high resolution and resistance to thermal drift.

Test stands: For material and product testing, where extreme accelerations and speeds are common, FLUX encoders provide accurate results unaffected by high vibration or rapid changes in motion.
