System description
2.11 Connection of probes and extensions
2.11.1 M8 connection
The PH10T is designed to carry Renishaw probes and extensions with an M8 screw
thread (see figure 10).
Probes and extensions are screwed into the probe head’s bush and tightened with the
appropriate spanner.
CAUTION: Never use anything other than the Renishaw spanner provided and
do not apply excessive force.
PEL1 extension
PEL2, PEL3 or
PEL4 extension

2.11.2 Autojoint connection
PH10M and PH10MQ heads use a Renishaw autojoint (figure 11) which is a highly
repeatable kinematic joint, one half of which forms part of the head. The other half
forms part of the adaptor, extension bar or probe.
Locking and unlocking the autojoint is carried out either manually, using the autojoint
key, or automatically using the Renishaw autochange rack system. In both cases, the
connection’s repeatability eliminates the need for probe requalification after exchange.
