PHS-2 servo positioning head

Servo positioning 2-axis motorised head with ±184° servo drive enabling the probe configuration to be positioned at almost any angle

The PHS-2 servo positioning head features continuous servo drive in two axes, enabling the probe configuration to be positioned at almost any angle
The PHS-2 head is not locked into position in the same way as a PH10 PLUS indexing head. Instead it is driven to the required position and, when a probing point is taken, the axes of the head latch simultaneously with the axes of the CMM to give accurate measurements
A range of different probes can be fitted and automatically exchanged. These include touch-trigger probes and third-party laser / optical sensors
