Care of equipment
Renishaw probes and associated systems are precision tools used for
obtaining precise measurements and must therefore be treated with
care.

or software without incurring any obligations to make changes to
Renishaw equipment previously sold.
Warranty
Renishaw plc warrants its equipment provided that it is installed
exactly as defined in associated Renishaw documentation.
Prior consent must be obtained from Renishaw if non-Renishaw
equipment (e.g.interfaces and/or cabling) is to be used or substituted
for Renishaw equipment.Failure to comply with this will invalidate the
Renishaw warranty.
Claims under warranty must be made from authorised service centres
only, which may be advised by the supplier or distributor.

4Introduction
1 Introduction
The PH6M is a shank mounted, fixed orientation, probe head
incorporating the Renishaw autojoint probe connector.
The PH6M is compatible with the AM1 adjustment module to allow
precise autojoint alignment with machine axes, enabling trouble-free
autochange operation.
Probe reach may be extended using the PEM range of extension bars
for multiwired probes or the PAA series for adapting to M8 connected
probes.
Electrical connection is made via a 15-pin micro ‘D’type connector.
A range of mating cables is available with the remote end either
terminated or unterminated according to installation requirements.
An integral LED indicates the status of touch-trigger probes.

Installation and connection
2 Installation and connection
The PH6M is fitted with an integral 15-pin micro ‘D’socket. If required,
this socket can be adapted by using a suitable cable to which a 5-pin
DIN socket has been fitted.
Locking and unlocking the autojoint is performed either manually
using the S10 joint key (supplied) or automatically using the Renishaw
autochange system. This allows probes to be changed without the
need to requalify.

Operation
4 Operation
The autojoint is a highly repeatable coupling mechanism which will
minimise the need for tip re-qualification after the exchange of probes
or extension bars. The locking mechanism is operated by rotating an
actuator contained in the mating half of the coupling, which is located
on the probe or extension bar. The actuator has a drive slot which
may be operated using an S10 joint key for manual probe or extension
bar changing applications (see figure 2 on page 8). Automatic probe
or extension bar changing is possible using the Renishaw ACR1 or
ACR3 autochange systems.
The status of the probe is indicated by the probe status LED.This is
normally lit when the probe is ready for use and extinguishes as the
probe triggers.

There is a choice of standard cables to connect from PH6M to probe
interfaces PI 7-2, PI 200, OPI6, the AC2 card for SP600M or the ACR3
card for SP25M.
Connectors shown in brackets are supplied in kit form.The cable
is supplied with the micro ‘D’connector fitted and the remote end
prepared, but unterminated, to facilitate assembly into machine looms.
