Kinematic probe system
with module changing
The TP20 touch trigger probe enables manual or automatic
stylus changing without re-qualification. This allows complex
part measurement, where a range of stylus configurations is
needed to access all features on the part.
Modules offering a range of trigger forces allow the probe
performance to be accurately matched to the measurement
task. A set of probe extensions is also available, as is a 6-way
module, allowing the inspection of features with restricted
access.
The TP20 can be used on a wide range of Renishaw’s manual
or motorised probe heads, either by direct mounting using the
standard M8 thread or alternatively, by using a PAA adaptor to
connect with the autojoint on the head.
The optional MCR20 module changing rack can store up to
six probe modules for automatic changing under
measurement program control. The probe is automatically
disabled during the change cycle.
The MSR1 can store up to 6 probe modules for manual stylus
changing and safekeeping when not in use.

Available modules:
LF = low force
(green cap)
Suited to applications that require a low trigger force.
SF = standard force
(SF, EM1 and EM2)
(black cap)
Suited to a majority of applications.
MF = medium force
(grey cap)
For use when a higher trigger force higher than ‘SF’
is required.
EF = extended force
(brown cap)
Required with large stylus assemblies. Also, to
eliminate spurious triggers due to machine vibration
ａnd acceleration.
6 W = 6-way probe
