PHA3 and PHA80 adaptor plates

The CMM quill must first be fitted with a KM1 or KM2 (kinematic mounting plate) as appropriate, to which the PHA3 / PHA80 mounts via a repeatable kinematic joint featuring quick lock/unlock by simply turning a key. The PH10MQ PLUS has to be pre-mounted on the PHA3 and similarly the SP80 to the PHA80. The general mechanical scheme is shown below.

The PHA80 is a single-piece item with the KM1 / KM2 joint on its top face, and a direct mount to the top of the SP80 probe body on its bottom face. Therefore the KM80 is not required.

The PHA3 is supplied in two pieces - the PH10MQ PLUS is first mounted to the lower hollow piece making a subassembly, then the electrical connectors are attached before bolting this sub-assembly to the bottom face of the upper piece which has the KM1 / KM2 joint on its top face.

It is possible to incorporate the IS1-2 interface selector unit into the system interconnection scheme.
