Introduction
The MH20 and MH20i are manually operated probe heads that articulate to provide orientation of the probing axis. MH20 provides non-
repeatable orientation, while MH20i permits repeatable indexing at 15° increments marked on the A and B axes. Both heads feature TP20
kinematic (magnetic) probe mounting, allowing stylus module changes without the need for re-qualification. A range of shanks is available to
suit most CMM quills.

Product description
MH20
The MH20 incorporates the TP20 kinematic mount with 2-axis adjustable swivel. The TP20 module is carried on the A-axis swivel and rotates
through ±93° in the Z‐plane. The B‐axis rotates through ±300° in the X‐Y plane. A thumbwheel locks the swivel in any position within the
movement envelope of the head. After each adjustment qualification must take place. Module changing is possible without re-qualification.
MH20i
The MH20i incorporates the TP20 kinematic mount with 2-axis indexing. The TP20 module is carried on the A-axis swivel and rotates through
90° in the Z‐plane. The B‐axis rotates through ±180° in the X‐Y plane.
The axes are unlocked by releasing the locking lever allowing rotation to each position. Positions are set at angular increments of 15° in each
axis, providing a total of 168 positions.
When head orientation is locked, the probe is fully kinematically constrained in a highly repeatable spatial position.
This means that after initial qualification of the stylus tip, the probe may be moved to any of the qualified positions without the need for re-
qualification during a gauging routine.
MH20 and MH20i
The red LED on the front of the head indicates probe status, and can be controlled by either the CMM or a Renishaw probe interface.
Conventionally LED ON indicates probe seated (armed), and LED OFF indicates probe triggered.
Electrical connection is via a 5-pin DIN connector.
