Probing systems forco-ordinate measuring machinesTP20 / TP20 NI modular probesThe TP20 is a 5-way or 6-way kinematic touch-Touch-trigger probeswith stylus module changing3-4trigger probe. Its two piece design comprises aprobe body and detachable stylus module(s),which gives the ability to change stylusconfi gurations either manually or automaticallywithout re-qualifi cation of the stylus tips, providingsignifi cant time savings in inspection routines.A direct replacement for the industry standardRenishaw TP2 probe, the TP20 probe systembrings a range of new benefi ts to manual andDCC CMM applications, and can easily beretrofi tted to existing TP2 installations.The TP20 can be used on a wide range ofRenishaw’s manual or motorised probe heads,either by direct mounting using the standard M8thread or, alternatively, by using a PAA# adaptorto connect to an autojoint.TP20 probebodyTP20stylus module(7 variants)The system components are:• TP20/TP20 NI probe body• TP20 stylus module – seven module variantsallow for optimisation of performance to suitthe application• MCR20 module changing rack – automaticoperation• The TP20 probe system may be used withRenishaw’s PI 4-2, PI 7-2 or PI 200 probeinterfaces (see section 9)M8 × 1.25 threadTP20 probe bodyThe TP20 probe body houses one half of thehighly repeatable magnetic kinematic couplingthat attaches the stylus module and body. Thebody also contains a magnetic proximity switchto inhibit triggering of the probe during automaticmodule changing with MCR20.NOTE: If the probe is operated close tomagnetised parts/clamping etc, the probetrigger may become inhibited. Countermeasuresinclude the use of long styli, stylus extensions orbody orientation to increase the distance to themagnetic source. Alternatively, use the TP20 NIprobe body.Ø13.2 mm(0.52 in)3 mm(0.12 in)M2 × 0.4 thread14° 14°9 mm (0.35 in)SF/LF/MF/EF 38 mm (1.50 in)6W 42 mm (1.65 in)EM1 88 mm (3.46 in)EM2 113 mm (4.45 in)+Z overtravelTP20 NI probe bodyThe TP20 NI probe differs from the TP20 body inthat it is not affected by magnetic fi elds.
