The probe module
Each probe module houses the touch trigger mechanism that carries the stylus assembly. The module provides overtravel in the X, Y and Z
axes. The M2 stylus mounting is compatible with Renishaw's comprehensive range of M2 styli.
Electrical contact pins automatically complete the probe circuit.
Trigger force and length option
Seven versions of the TP20 probe module can be used with the MH20 and MH20i, they can be identified by the end cap colour.

TP20 6-way probe module
Blue cap
Medium and extended force modules are used to overcome the effects of false triggers, caused either by stylus length and mass, or vibration
caused by machine acceleration forces.
The low force module permits the measurement of delicate objects.
The EM1 and EM2 extended modules allow access to otherwise inaccessible workpiece features. Both operate using standard force and offer
better measuring performance than using long styli with MF, or EF modules.
The TP20 6-way senses in the +Z and -Z directions, allowing undercuts to be checked.
