RENISHAW – TP20/TP20 NI Modular Probes
Brand: Renishaw
TP20 probe body
The TP20 probe body houses one half of the highly repeatable magnetic kinematic coupling that attaches the stylus module and body. The body also contains a magnetic proximity switch to inhibit triggering of the probe during automatic module changing with MCR20.
Note: If the probe is operated close to magnetize parts/clamping etc, the probe trigger may become inhibited. Countermeasures include the use of long styli, stylus extensions or body orientation to increase the distance to the magnetic source. Alternatively, use the TP20 NI probe body.
TP20 NI probe body
The TP20 NI probe differs from the TP20 body in that it is not affected by magnetic fields. However, the probe trigger must be inhibited through software during change cycles using the MCR20.
The above data applies for test conditions as follows:
