How to Get FLUX Encoders in the UK. A Guide to GMI® and Inductive Position Feedback

If you are a design engineer, systems integrator, or procurement manager in the United Kingdom searching for a high-precision position encoder that genuinely outperforms traditional optical, magnetic, and inductive alternatives (without their well-known compromises) this guide is for you.

FLUX GmbH manufactures some of the most advanced absolute rotary encoders available today, built on two proprietary technologies that are redefining what engineers can expect from position feedback systems. And in the UK, you can access the full FLUX portfolio through a single local partner: Torquety.

In this article, we cover the complete FLUX encoder range (GMI® Angle, GMI® Rotary, IND-ROT, and IND-MAX) with full technical specifications, application guidance, and a clear path to sourcing them in the UK.

Why UK Engineers Are Turning to FLUX

For decades, specifying a rotary encoder meant choosing between three imperfect options:

TechnologyStrengthTrade-off
OpticalHighest accuracyFragile glass disc, sensitive to dust, oil, and vibration
MagneticLarge mounting tolerances, robustHysteresis errors, limited accuracy
InductiveCompact, robustHistorically lower resolution and accuracy

Engineers accepted these trade-offs because no single technology could deliver all three: precision, robustness, and ease of installation.

FLUX changed that.

Their patented GMI® (Giant Magneto Impedance) technology and IND (Inductive) technology each eliminate the traditional compromises, delivering optical-grade accuracy in a rugged, IP67-rated, calibration-free package.

For UK industries operating in demanding environments; subsea installations off Aberdeen, vibration-intensive aerospace test rigs in Bristol, agricultural autonomy across East Anglia, or cleanroom medical device manufacturing in the Midlands, FLUX encoders offer a step-change in performance and reliability.

What Is FLUX?

FLUX GmbH is an Austrian encoder manufacturer headquartered in Braunau am Inn, backed by more than 40 years of collective experience in position feedback systems. Founded in 2017 by engineers who had spent decades designing magnetic, inductive, and optical encoders, FLUX was created with a singular mission: build an encoder that combines the best attributes of every existing technology, without compromise.

The result is a portfolio of absolute, frameless, hollow-shaft encoders that deliver:

  • Arcsecond-level accuracy: rivalling optical systems.
  • IP67 environmental protection: matching the toughest inductive encoders.
  • Wide mounting tolerances: comparable to magnetic encoders.
  • Plug-and-play installation : no field calibration required.
  • Maintenance-free, bearingless operation: no mechanical wear, no scheduled servicing.

FLUX designs and manufactures high-performance encoders for precise position and velocity feedback within closed-loop motion control systems. Their encoders are used across robotics, industrial automation, medical technology, aerospace, automotive, and precision measurement applications worldwide.

The Two FLUX Technologies Explained

GMI®: Giant Magneto Impedance (Patented)

The GMI® effect is a physical phenomenon that relies on the skin effect: a sensor material’s impedance changes significantly when exposed to an external magnetic field. FLUX harnesses this interaction between magnetic field and electromagnetic induction to create a position measurement system that delivers:

  • Hysteresis-free operation: real-time 360° scanning with zero jitter.
  • Arcsecond accuracy: comparable to the best optical encoders.
  • Robustness of inductive technology: no fragile glass disc.
  • Wide mounting tolerances: comparable to magnetic encoders, simplifying mechanical design.

GMI® encoders come in steel or aluminium housings with IP67 protection and require no field calibration — they deliver full specified accuracy straight out of the box.

IND: Inductive Technology

FLUX’s inductive technology takes a fundamentally different approach, enabling the creation of the smallest and most precise inductive absolute encoders on the market:

  • Ultra-flat form factor: thickness under 6 mm.
  • Featherweight: total weight just 14 grams.
  • Open PCB design: maximum integration flexibility.
  • Complete immunity to electromagnetic interference (EMI): can be mounted directly inside motor housings alongside permanent magnets and high-current coils.

This makes IND encoders ideal for direct integration into BLDC motors, stepper motors, robotic joints, and actuators where every millimetre and every gram matters.

Why FLUX Encoders Stand Out in the UK Market

Unlike general-purpose encoder suppliers in the UK who focus heavily on repairs, replacements, and generic equivalents, FLUX is engineered for new-design, high-performance systems. Here is what sets them apart:

No Calibration, No Downtime

Every FLUX encoder delivers its full specified accuracy straight out of the box. Wide mounting tolerances mean your mechanical team spends less time on alignment and your commissioning cycle drops from days to hours.

Bearingless and Maintenance-Free

With no bearings, no glass disc, and no mechanical contact between rotor and stator, there is nothing to wear out. This is critical for remote or difficult-to-access installations (offshore wind turbines, subsea platforms, or sealed defence systems) where scheduled servicing is impractical or impossible.

Hysteresis-Free Operation

Real-time 360° scanning delivers jitter-free position feedback for optimal motion control loop performance. Unlike magnetic encoders that suffer from hysteresis errors (where the output depends on the direction of approach), FLUX encoders produce a clean, repeatable signal regardless of direction.

Extreme Temperature Range

Standard models operate from -40°C to +85°C, with extended versions rated to +125°C and storage capability down to -55°C. This makes them suitable for aerospace, automotive test environments, industrial freezers, and outdoor installations in all UK weather conditions.

Validated for Shock and Vibration

FLUX encoders are subjected to rigorous testing including thermal cycling, vibration, shock, humidity, corrosion, and outgassing tests (for aerospace and vacuum environments). Their bearingless design inherently eliminates the most common mechanical failure modes found in conventional encoders.

CAD Models Available

STEP files are available for the full FLUX encoder portfolio, enabling rapid integration into your 3D mechanical design environment before committing to a purchase.
