MH20i Probe Head with Standard Force Module

Manual indexable probe head that combines the TP20 kinematic stylus module mount with two axis indexing, enabling flexible stylus changing and repeatable probe re-orientation.

The A-axis rotates through 90° in the Z plane.The B-axis rotates through ±180° in the X-Y plane. A lever locks the head in one of up to 168 repeatable positions, set at 15° increments.

The head is capable of carrying the full range of TP20 modules, which can be changed without re-qualification, providing qualification has taken place in each position with each stylus / module combination.
