The HH-A-T2.5 is capable of indexing in 2.5° increments and can achieve 12,240 unique positions.

The head is fitted with a kinematic joint (TKJ) which can be connected to a Multiwire to give multi sensor support.

The TKJ can be changed either manually without the need for requalification or automatically with the HR-R tool changer.

The HH-A-2.5 range of probe heads feature a number of new innovations including an fully embedded controller, capacitive crash protection and the all new heavy duty kinematic joint.

All of the probe heads in the range benefit from a completely redesigned drive system including a Hirth Gear for accurate positioning of the probe. The new design delivers the advantage of a high degree of indexable positions and very high rotational torque.

The HH-A-2.5 can either be mounted on the CMM with a shank or flange, alternatively the HH-AS8-2.5 can be mounted on any CMM with an 80mm ram.
