Touch Probes - TP20
The TP20 is a kinematic touch probe with the facility to change
stylus configurations without requalification. Both 5-way and 6-
way modules are available.

The TP20 probe is a two-piece design comprising a probe body
and a detachable probe module. The TP20 probe may be
directly fitted to all Renishaw M8 probe heads and to Renishaw
autojoint system probe heads with a PAA range of adaptors /
extensions. The TP20 is compatible with all electronic interfaces
which currently service the TP2 and the TP6 touch trigger
probes. Changing of the modules may be performed either
manually or automatically under measurement program control
using the optional MCR20 module change rack.
