AUBURN, Mass. — The H-845 is a new series of preconfigured high-load hexapods by PI (Physik Instrumente) LP.
Offering six-axis precision motion for loads up to 1 metric ton, the devices have applications in areas including precision assembly, testing and manufacturing, astronomy, aviation, aerospace and high-energy physics research.
The series is designed for complex, multiaxis precision motion applications with models available in various travel ranges, load capacities and velocities. It features six degrees of freedom (X, Y, Z, pitch, roll and yaw), no moving cables and a large clear aperture.
The hexapods achieve step sizes from 0.5 μm and repeatability to 2 μm, with linear travel ranges to 340 mm and rotation ranges to 60°. Each device has a C-887 vector motion controller, which powers the six hexapod axes and two additional motorized single axes. Position values can be commanded as Cartesian coordinates. The center of rotation can be changed with a software command.
