TESASTAR-mp StyliTouch Trigger Probe with Stylus Module Changing

TESASTAR-mp is a 5-way kinematic touch trigger probe that consists of two parts: the sensor body and the stylus holding module. The sensor body is not affected by magnetic fields. It can be fitted to any probe head featuring a M8 connection.

The stylus holding modules can be quickly changed in manual or automatic mode without the need for requalification through a highly accurate and repeatable magnetic isostatic clamping system.

The stylus holding module houses the kinematic switching touch sensor mechanism. It is available in four versions that have the same size but different trigger forces.

Part No.

Different kits are available with different probe configurations.
