Renishaw manufactures a comprehensive range of extension bars and adaptors to allow increased component penetration.
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 PLUS or PH10MQ PLUS head and terminate in an M8 bush. This permits
the use of two-wire touch-trigger probes.
Extensions Length Material Weight
PAA1 32 mm Steel 57 g
PAA2 144 mm Aluminium 85 g
PAA3 300 mm Aluminium 144 g
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).
