This is the TP20 probe kit 5 #A-1371-0294. It includes one medium force (MF) module and one extended force (EF)  module.

The standard Renishaw TP20 touch-trigger probe kit comprises the following primary components:

• One TP20 probe body
• One or two TP20 probe modules (see TP20 probe kits for available combinations)
• Probe and stylus tools

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 medium force probe module, identified by a grey cap, is suited to applications where a higher trigger force than standard is required. The medium force probe module has the following recommended stylus limits:

• Any stylus type up to 60 mm long
• Star and cranked styli up to 20 mm offset

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. The extended force probe module has the following recommended stylus limits:

• Any stylus type up to 60 mm long
• Star and cranked styli up to 20 mm offset
