Probe extension bars

Renishaw manufactures a comprehensive range of extension bars and adaptors to allow increased component access.

There are three types in the range:

• Autojoint to M8 bush (PAA series)
• Autojoint to autojoint (PEM series)
• M8 thread to M8 bush (PEL series)

Autojoint to M8 bush

These extension bars connect directly to the autojoint of the PH10M-iQ PLUS head and terminate in an M8 bush. This permits the use of two-wire touch-trigger probes.

The probe is fitted to the extension by hand and tightened by use of the S1 ‘C' spanner as shown.

The S1 spanner is designed to fail before damage can occur to the mechanical joint between the two parts. Using the S1 spanner, fully hand-tighten the probe body into the M8 bush (0.3 Nm to 0.5 Nm).

Autojoint to autojoint

These extension bars are compatible with the PH10M-iQ PLUS head. They allow direct connection to the head via the autojoint and terminate in an autojoint. This permits use of a multiwired probe.
