MIH-S legacy head


The MIH-S (manual indexable head - serial) utilises an RS232 link, via the MIH-SI interface, to provide feedback of status and lock position to the CMM computer.

This enables the CMM computer to:

  • verify that the MIH-S has been moved to the correct position and locked in place
  • identify the position which the MIH-S has been locked into

Measurement performance, functionality and dimensions are the same as for the MIH.
