This is the MIH-S Probe #A-1373-0001.
It is a derivative of the well-established MIH design with enhanced functionality to provide feedback of status and lock position over an RS232 serial communications link.
The MIH-S (manual indexable head – serial) utilizes 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 and identify the position which the MIH-S has been locked into. Measurement performance, functionality and dimensions are the same as for the MIH.
