TP20 modules
TP20 stylus modules
The TP20 stylus module houses the kinematic switching touch sensor mechanism, carries the stylus assembly and provides overtravel in ±X, ±Y and +Z axes (or ±Z in the case of TP20 6-way module). The stylus mounting thread accepts styli from the Renishaw M2 range.
A range of seven, application specific, stylus modules is available, being identified by coloured caps:

SF
Standard force stylus module (black cap)
LF
Low force stylus module (green cap)
MF
Medium force stylus module (grey cap)
EF
Extended force stylus module (brown cap)
6W
6-way stylus module (blue cap)
EM1 SF
Standard force extension module
EM2 SF
Standard force extension module
MCR20 module changing rack
The MCR20 probe module changing rack is designed to securely store stylus modules ready for rapid automatic changing, whilst protecting mating surfaces from any airborne contaminants within the working environment.
MSR1 module storage rack
For manual storage of modules – see MSR1.
Probe maintenance - CK200 (A-1085-0016) is a specialised cleaning material supplied for the removal of contamination from the location faces of the magnetically retained kinematic couplings of the TP20, TP200 and SP25M probe systems. The frequency of cleaning should be determined by the conditions of use.

Specification
| Module | Application guide | Maximum extension on PH10 series head | Weight (body and module) |
|---|---|---|---|
| LF | The low force stylus module, identified by a green cap, is suited to applications that require low trigger force, e.g. rubber seals. | 300 mm (11.81 in) | 22 g (0.78 oz) |
SF EM1 EM2 | The standard force stylus modules, identified by black caps, are suited to the majority of applications. | 300 mm (11.81 in) 300 mm (11.81 in)* 300 mm (11.81 in)* | 22 g (0.78 oz) 28 g (0.99 oz) 30 g (1.06 oz) |
| MF | The medium force stylus module, identified by a grey cap, is for use where a higher trigger force than standard is required. | 300 mm (11.81 in) | 22 g (0.78 oz) |
| EF | The extended force stylus module is identified by a brown cap. Typically, this stylus module will only be required with large stylus assemblies, and where spurious ‘air' triggers caused by machine vibration and acceleration, preclude the use of either SF, LF or MF modules. | 300 mm (11.81 in) | 22 g (0.78 oz) |
| 6W | The 6-way stylus module, identified by a blue cap, has been designed for applications requiring measurement in the –Z direction, for example when measuring the width of undercuts. | 300 mm (11.81 in) | 22 g (0.78 oz) |
Module type and test stylus length | Trigger force XY** | Trigger force Z | Overtravel force XY | Overtravel force +Z | Overtravel force -Z | Overtravel displacement XY | Overtravel displacement +Z | Overtravel displacement ‑Z |
