The MH20i is a manually adjustable indexing probe head with integral TP20 Touch Probe body allowing use of the TP20 magnetic stylus modules. The A-axis rotates through ±180° in the X-Y plane in 15° increments while the The B-axis rotates through 90° in the Z plane again in 15° increments. A manually adjusted lever locks the head into one of its 168 repeatable positions.
The head is capable of carrying the full range of TP20 modules, which can be changed without re-qualification, providing qualification has previously taken place in the required position with each stylus/module combination.
The PH20i is most suitable for use on manually operated CMMs or on smaller DCC units where numerous probe indexes are not required to be carried out automatically. A version of the PH20i allowing automated indexing is available for DCC CMM and is called the RTP Indexing Head.
The MH20i is a replacement for the MIP which is no longer produced by Renishaw.
