Non-magnetic hexpaod
Our hexapods with stable or zero magnetic fields
Non-magnetic hexapods for magnetic field-sensitive environments
High-precision positioning without magnetic interference
Some scientific research, quantum physics, and experimental applications require completely non-magnetic positioning systems in order to avoid any disturbance of magnetic fields or interference with sensitive measuring instruments (SQUID sensors, magnetic resonance, magnetic imaging, etc.).
Symétrie’s non-magnetic hexapods are specially developed for these critical environments. Their design ensures operation without electromagnetic interaction, while maintaining the mechanical rigidity and sub-micron positioning accuracy characteristic of Symétrie systems.
Non-magnetic design and optimized architecture
Each non-magnetic hexapod is designed using materials carefully selected for their lack of ferromagnetic properties and dimensional stability:
- Non-magnetic aluminum alloys, titanium, or bronze, depending on mechanical and thermal constraints.
- Screws, pins, and guide elements made of non-magnetic austenitic steel or technical ceramics.
- Non-magnetic motors (piezoelectric motors, direct-drive linear actuators, or special actuators).
- Absolute linear encoders guaranteeing precise position feedback without magnetic sensors.
- Ultra-flat “hexaglide” architecture, ensuring stable and rigid kinematics while minimizing the overall height of the system—an advantage for integration in vacuum chambers or between superconducting magnet poles.
The absence of ferromagnetic components ensures neutral behavior with respect to static and variable fields, which is essential for sensitive research environments.

FAQ
What kinds of movements can the Symétrie hexapod perform?
The hexapod can perform combined movements across its six degrees of freedom: three translations (X, Y, Z) and three rotations (Rx, Ry, Rz). This flexibility allows for complex adjustments that would be impossible with conventional guidance systems.
What is the accuracy or resolution of the movements?
Our hexapods achieve resolutions of around 50 nm for linear motion and a few microradians for rotational motion. Repeatability is one of our key strengths, ensuring the accuracy of every positioning operation.
What materials are used to make the hexapod?
We use high-performance materials such as anodised aerospace-grade aluminium, stainless steel and components specifically designed for demanding environments (vacuum, cleanroom, non-magnetic).
Is it compatible with different software or control systems?
Absolutely. We provide function libraries (SDKs) compatible with LabVIEW, C++ and Python, as well as specific interfaces for research environments such as EPICS and TANGO.
Is the hexapod safe for use in laboratories or in industry?
Safety and reliability are at the heart of our design. The software features configurable travel limits, virtual collision detection and hardware safety features to protect your equipment and samples.
