In the fast-evolving world of Industry 4.0, staying ahead means embracing innovations that push the boundaries of what’s possible. At FLUX, our Giant Magneto Impedance (GMI) encoders are setting new standards for precision and adaptability in diverse applications.

Why GMI Encoders Are a Game-Changer

Our revolutionary GMI technology is a principle that has been around but is now harnessed in a way that transforms encoder technology. The GMI effect involves a material’s change in impedance when exposed to an external magnetic field, which can then be used to measure rotational or linear movement with unprecedented accuracy.

FLUX’s GMI encoders leverage this principle to deliver performance that goes beyond the limitations of traditional sensors. With their advanced design, these encoders are ideal for machine tools, gyro-stabilized platforms, and high-performance test stands.

FLUX’s Encoder Portfolio

FLUX has three key product lines, two of which utilise GMI technology:

GMI® Angle Encoder (GMI-ANG Series): Provides ultra-fast and precise angle measurements in arcseconds, making it perfect for high-demand applications that require exacting standards.

GMI® Rotary Encoder (GMI-ROT Series): Delivers the benefits of GMI technology in compact spaces, addressing the challenges where traditional encoders fall short.

INDUCTIVE Rotary Encoder (IND-ROT Series): Complements the GMI range with robust and accurate inductive technology encoders, with the IND-ROT Minis being the smallest and most precise on the market.

Applications That Benefit from GMI Encoders

Machine Tools: Our GMI Angle Encoders excel here due to their bearing-less design, which eliminates wear and tear issues associated with traditional encoders. They offer real-time data collection with angular accuracy of ±4 arcseconds, ensuring optimal performance even in challenging environments.

Gyro-Stabilized Platforms: Used in cameras and optical devices, these platforms require encoders that can withstand vibrations and temperature extremes. GMI Rotary Encoders meet these demands 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’s encoders offer precise results without being affected by high vibrations or rapid changes in movement.

Position encoders play a crucial role in satellite communications (Satcom) by ensuring accurate alignment and positioning of satellite dishes and antennas. Selecting the right position encoder is important for maintaining optimal signal quality and reliability. In our latest blog, we examine the key factors to take into consideration when choosing the right position encoders for Satcom applications.

1. Accuracy and Precision

The primary requirement for position encoders in Satcom is high accuracy and precision. This ensures antennas are properly aligned with satellites which helps maximise signal strength and minimises errors. Encoders with high resolution and minimal angular error are needed for precise positioning.

2. Durability and Environmental Resistance

Satcom equipment operates within harsh environmental conditions, such as extreme temperatures, and humidity. This means the encoders must be rugged and designed to withstand such conditions. Ensure your encoders have robust housings, corrosion-resistant materials, and certifications for environmental resistance (e.g., IP67 ratings) to excel in difficult environments.

3. Reliability and Longevity

Given the importance of Satcom operations, reliability and longevity of encoders are vital. Encoders should have a proven track record of long-term reliability with minimal maintenance requirements. GMI and inductive encoders are often favoured for their durability and consistent performance over time.

4. Integration and Compatibility

Position encoders must integrate seamlessly with the existing Satcom infrastructure. They should be compatible with the control systems, feedback loops, and communication protocols used in the antenna positioning system. Encoders with standard communication interfaces (like SSI, RS-485, or CANopen) make it easier to connect and work with other systems.

5. Speed and Responsiveness

In dynamic Satcom applications, such as mobile satellite systems, the speed and responsiveness of position encoders are critical. Encoders need to provide real-time feedback to enable rapid adjustments and maintain precise alignment with moving satellites. High-speed encoders with low latency are essential for these applications.

Given the rapid advancements in industrial automation and the increasing complexity of system integration, encoder performance has become crucial for effective industrial motion control. Harsh environmental conditions, including exposure to dust, dirt, liquids, and extreme temperatures, pose common threats to the performance of existing encoder technologies, potentially leading to failures and limiting their applications in various fields.

Superior Performance in Extreme Conditions

The GMI® Angle Encoder series stands out for its exceptional performance in harsh environments, seamlessly combining the high-precision capabilities of an optical encoder, the robustness of an inductive encoder, and the broad mounting tolerance and expansive working range of a magnetic encoder. The IP67 stainless steel housing, paired with an extended temperature range spanning from -55 to 125 degrees Celsius, guarantees arcsecond accuracy and a resolution of up to 25 bits. These features have been proven in applications across industrial automation, robotics, and defense.

Key attributes of the GMI Angle Encoder include hysteresis-free performance, real-time position detection, plug-and-play operation, and wide mounting tolerances, offering maximum flexibility and efficiency. This not only enhances overall performance but also contributes to a reduction in total implementation costs associated with installation, integration, operation, and maintenance.

Braunau am Inn, Austria – June 14, 2024 – FLUX GmbH (FLUX), a high-precision encoder company, has announced sponsorship of the Technology University of Munich’s DASH student initiative developing and building lower-limb exoskeletons for fully paraplegic patients.

The DASH team, made up of bachelor, master and PhD students, plans to compete with its exoskeleton at CYBATHLON 2024, a groundbreaking event organized by ETH Zürich celebrating the latest advancements in assistance technologies. This year’s event takes place from 25-27 October.

FLUX has provided the DASH team with a range of lightweight and compact inductive rotary encoders which will be used to provide precision position and speed feedback in the joints of the exoskeleton.

“We are proud to support the next-generation of engineers at the Technology University of Munich working on such a meaningful project,” said Paul Tutzu, Managing Director & Founder of FLUX GmbH. “We wish the team all the best for their developments and look forward to seeing the end result at CYBATHLON 2024.”
