m&h Infrared Touch Probe IRP40.01

m&h IRP40.01 - with patented THERMO-LOCK® technology!

The infrared touch probe IRP40.01has been designed for machining centres and turning machines. Its compact construction makes it ideally suited for use even the smallest shanks. Equipped with a patented THERMO-LOCK® Technology shank, the touch probe delivers precise results even with large temperature differences. The bi-directional IR communication makes use in special production machines possible.
