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 TP20 NI (non-inhibit) probe body is not affected by magnetic fields and the probe trigger must be inhibited through software during change cycles using the MCR20. The medium force probe module is identified by a grey cap. This probe module is designed for applications where a higher trigger force than standard is required. The recommended stylus limits for the medium force probe module are:•Any stylus type up to 60 mm long•Star and cranked styli up to 20 mm offset The low force probe module is identified by a green cap. This probe module is designed for applications that require a low trigger force to measure workpiece deflection. The recommended stylus limits for the low force probe module are:•Steel and carbide styli up to 30 mm long•No star or cranked styli
