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 20 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 dynamics, 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.
PIVirtualMove
The simulation software simulates the limits of the workspace and load capacity of a hexapod. Therefore, even before purchasing, 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 the position and motion of the hexapod as well as the pivot point and several reference coordinate systems into account.
Application fields
Industry and research. For micromanufacturing, medical technology, tool inspection.

When measuring position specifications, typical velocity is used. The data is included in the delivery of the product in the form of a measurement report and is stored at PI.
The maximum travel ranges of the individual coordinates (X, Y, Z, θX, θY, θZ) are interdependent. The data for each axis shows its maximum travel range when all other axes are in the zero position of the nominal travel range and the default coordinate system is in use, or rather when the pivot point is set to 0,0,0.
At PI, technical data is specified at 22 ±3 °C. Unless otherwise stated, the values are for unloaded conditions. Some properties are interdependent. The designation "typ." indicates a statistical average for a property; it does not indicate a guaranteed value for every product supplied. During the final inspection of a product, only selected properties are analyzed, not all. Please note that some product characteristics may deteriorate with increasing operating time.

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.
