H-811.I2 6-Axis Miniature Hexapod
Fast, Compact, and Highly Precise
- Travel ranges to ±17 mm / ±21°
- Load capacity to 5 kg
- Repeatability to ±0.06 µm
- Velocity to 10 mm/s
- Vacuum version available
Reference-class 6-axis positioning system
Parallel-kinematic design for six degrees of freedom making it significantly more compact and stiff than serial-kinematic systems, higher dynamic range, no moved cables: Higher reliability, reduced friction.
Brushless DC motor (BLDC)
Brushless DC motors are particularly suitable for high rotational speeds. They can be controlled very accurately and ensure high precision. Because they dispense with sliding contacts, they run smoothly, are wear-free and therefore achieve a long lifetime.
PI Hexapod Simulation Tool
The simulation software simulates the limits of the workspace and load capacity of a hexapod. Therefore, even before making a purchase, you can check whether a particular hexapod model can handle the loads, forces, and torques occurring in an application. For this purpose, the simulation tool takes into account the position and motion of the hexapod as well as the pivot point and several reference coordinate systems.
Fields of application
Research and industry. For micromanufacturing, medical technology, tool inspection.

Technology

Active Alignment
The need to align devices down to nanoscale accuracy is arising in many fields. Optical components such as the lenses or lens assemblies in small cameras, or even the CCD chip itself, need to be positioned with ever more precision.

EtherCAT Connectivity of PI Products
PI offers high-precision drives for use as EtherCAT slave, or integrates with ACS Motion Controllers as Master, or 2nd Master in an existing architecture.

Multi-Axis Positioners
Hexapod platforms are used for precision positioning and alignment of loads in all six degrees of freedom, three linear axes, and three rotational axes.
Applications

Photonics Packaging
The assembly and packaging of photonic devices requires highly efficient production systems. The alignment is one of the biggest cost factor when producing these components since the it is repeated several times in the production process. PI's revolutionary Fast Alignment technology has been unsurpassed for these challenges.

Sample Adjustment
At Diamond Light Source, UK, beamline I07 is a high-resolution X-ray diffraction beamline dedicated to investigate the structure of surfaces and interfaces.

High Vacuum Positioning
Investigation of the structural properties of thin films under high-vacuum conditions.

Nanotomography
At the X-ray light source PETRA III at the DESY research center in Hamburg operates the Imaging Beamline P05.

Hexapods in Microproduction
What do optical components and glass fibers in photonics, mobile devices, and high-quality wristwatches all have in common?

Dimensional Measuring
Hexapods allow for an outstanding flexibility for a variety of samples of in-line automation systems by minimizing the space for motion robotics.
