HH-A-H2.5 / HH-AS-H2.5 Automatic HD Probe Heads

The HH-A-2.5 range of probe heads feature a number of innovations, including a fully embedded controller, and capacitive crash protection.


Heavy duty HD probe heads for the most challenging applications

The HH-A-H2.5 can index in 2.5° increments and achieve 20,736 unique positions due to increased rotation of the A Axis (± 180°).
The head is fitted with the heavy-duty kinematic joint (HDKJ), which can be connected to a multiwire to give full multi-sensor support.

The HDKJ carries extensions of up to 750mm. Laser scanners and scanning heads can be supported further from the rotation axis than conventional probe heads due to the combination of extreme rotational torque and the HDKJ adaptor.
