Usage example:Cam shaft O.D

High Precision

Built in optical technology allows higher precision measuring with a pencil probe that connects directly to a PC.

Small Size and Space Saving

Improved technology allows for a reduced size while maintaining superior accuracy.


PHA-13W and PHA-26W are IP67 certified.


By implementing a more rugged slide bearing, the PHA is able to withstand up to 200 million strokes in rigorous test conditions.
