GRI-PHI A, B, C – Piezoelectric Microgripper

Phi Drive presents the Gri-Phi piezoelectric microgrippers  to mount, assemble and manipulate increasingly small objects.

Manipulating, assembling, and mounting small objects is a job for professionals.

Gri-Phi features three different models; all of them are able to manipulate samples of different sizes.

Encoding GRI-PHI: choose the configuration which better suits your needs

Choose between the following options to create your requested code:

GS.9XNY

GS.9 series comes in two different product ranges, using different operational modes:

  • a = single effect, with only one arm moving;
  • b = double effect, with both arms moving.

GRI-PHI GS.9 series comes with a wide range of performance. Performance code is a number from 1 to 4, whose details can be evinced in the Technical Data.

GRI-PHI comes with 3 standard options for its jaws, as can be seen in the gallery below. This part of the gripper can be fully customized.

GRI-PHI grippers have been designed to operate under high vacuum conditions, in line with all the latest generation of Phi Drive products.
