The TP20 is a compact module changing touch-trigger probe. The two-piece design, comprising of a probe body and detachable stylus module(s), allows the use of a range of stylus configurations and extensions to access features on complex parts. Modules can be changed manually or automatically without the need for requalification of the stylus tip.

The extended force probe module is identified by a brown cap. Typically, this probe module will only be required with large stylus assemblies and where spurious triggers caused by machine vibration and acceleration preclude the use of either the standard or medium force probe modules.
