Infrared Touch Probe IRP40.42

Consistently low probing forces
The IRP40.42 was specially developed for measuring thin, fragile workpiece geometries. Its unique technology means it achieves the lowest possible contact forces also with high measuring speeds.

Optimised for measuring in very limited spaces
The measuring unit can be equipped with styli and measuring spheres as small as Ø 0.2 mm, making measurements in previously unreachable positions possible, including when space is limited.

Robust and durable
All mechanical components are IP68 standard protected and designed to withstand the harsh conditions of a machine tool. Extreme accelerations, high positioning speeds, constant vibrations, hard tool changes and elevated temperatures are no problem for the probe.

Innovative HDR+ Infrared Transmission
The HDR+ infrared transmission ensures that only the system’s own signals are processed. There is no interference from ambient light. An innovative design with mirrored surfaces, ensures it achieves homogeneous and true 360° directional transmission characteristics.

The best possible transmission quality is not just dependent on the probe, but also the receiver, which is mounted within the machine. The infrared receivers IRR91.50 and IRR91.42, which also work with HDR+ infrared transmission, can be used with additional Hexagon tool setters inside the machine. This ensures reliable transmission.
