PH10 legacy probe heads

PH10 range

Each of the heads in the PH10 motorised probe head range is a general purpose, versatile unit designed specifically for use on direct computer controlled (DCC) coordinate measuring machines (CMMs).

The range comprises three heads:

  • PH10T
  • PH10M
  • PH10MQ

All the heads in the range incorporate the following features:

  • 720 indexing positions
  • 0.5 µm (2 s) indexing repeatability
  • 7.5° indexing steps in both axes
  • 300 mm extension bar capability

Additionally, the PH10M and PH10MQ heads offer the following features:

  • Autochange compatibility
  • Multiwired probe compatibility

PH10 specification

Repeatability of position (2σ)

PH10T: <0.4 μm (0.00002 in) - equivalent to a TP20 and stylus (part number A-5000-3604)

PH10M / PH10MQ: <0.4 μm (0.00002 in) - equivalent to a TP6A and stylus (part number A-5000-3553)

Accuracy of step spacing from theoretical position

PH10T: ±0.24 mm (±0.012in) (using TP6 probe and stylus part number A‑5000-3553)

PH10M / PH10MQ: ±0.3 mm (±0.012 in) (using TP6A probe and stylus part number A‑5000-3553)


Step: 7.5°

A-axis 0° to 105°: 15 positions

B-axis -180° to +180°: 48 positions

Total: 720 positions
