The MH8 can carry any of Renishaw's M8 probes and the reach can be extended by fitting

a 50 mm probe extension bar.


Compact module changing touch-trigger probe, which allows the use of a range of stylus configurations and extensions to access features on complex parts.

About TP20


The TP20 is a compact 5-way, or 6-way, kinematic touch-trigger probe system. The two-piece design,

comprising probe body and detachable stylus module(s), connected using a highly repeatable magnetic

kinematic coupling. This provides the facility to change stylus configurations either manually or automatically

without the need for requalification of the stylus tips, thereby giving significant time savings in inspection

routines. Modules offering a range of trigger forces allow the probe performance to be best matched to

the measurement task. A set of probe extensions is also available, as is a 6-way module. The stylus

mounting thread accepts styli from the Renishaw M2 range. The TP20 system is easily retrofitted and is

compatible with existing touch trigger probe interfaces, extensions and adaptors.


System components


The system components are:

  • TP20 probe body
  • TP20 probe module - seven variants allow optimisation to suit application
  • MCR20 module changing rack - automatic operation
  • MSR1 module storage rack - manual operation
  • Suitable for interfacing with Renishaw's PI4-2, PI7-2 or PI200
