PH20 probe head

5-axis touch-trigger measurement system with integral TP20 probe and automatic module changing via TCR20 rack

  • Knowledgebase top level image - PH20Compact design - suitable for a wide range of CMMs using shank or quill mounting
  • Renishaw CMM controller - I++DME communication, wide selection of metrology software
  • Index head compatibility - no requirement to modify existing programs in the majority of cases
  • Integral TP20 probe - allows re-use of existing equipment
  • Mechanical bearings - no air supply required


PH20 - dimensions

NOTE: Dimensions in mm (in).

Dimension 'A'
Standard force module21 mm (0.83 in)
Medium force module21 mm (0.83 in)
Low force module21 mm (0.83 in)
6-way module25 mm (0.98 in)

Hardware integration

  • The PH20 system is only available with the UCC T5 controller
  • SPA3 is a servo power amplifier used to power the CMM
  • MCUlite-2 / MCU5-2 / MCU W-2 are the multi-function hand control units available for use with the PH20 system

Head axis range

The PH20 head has two rotary axes (A and B) and is normally mounted on the CMM quill to create a 5-axis measuring system.

The PH20 head's B-axis is mounted on the CMM quill and can rotate continuously in both directions.

The A-axis, which is orthogonal to the B-axis, has ±115° of travel.

The head can only be mounted in the vertical orientation shown below.
