Sensors can be connected to the Probe Head with a kinematic joint (HH-A-T7.5 and HH-AS-T7.5) or an M8 threaded connection (HH-A-M7.5 and HH-AS-M7.5).
The Probe Heads can index in 7.5° increments and achieve 720 unique positions.
The Probe Heads feature high-speed operation and high rotational torque. Sensors can be changed either manually or automatically (with the HR-R probe changer) without requiring requalification.
There are two ways of mounting the probe head to the machine. The HH-A-T7.5 and HH-A-M7.5 are equipped with a shank or flange fitting to the machine. The HH-AS-T7.5 and HH-AS-M7.5 can be mounted directly into any machine with an 80mm ram.
