Infrared Touch Probe IRP40.42

Low trigger forces and small styli balls for measuring delicate applications

The infrared touch probe IRP40.42 has been specially designed for measuring sensitive materials and thin, fragile workpiece geometries within harsh machine tool environments. The IRP40.42 combines the strengths of the IRP40.02 touch probe with a highly versatile touch trigger probe developed by Hexagon for taking fast, repeatable measurements on coordinate measuring devices.

The trigger forces of the IRP40.42 remain consistently low even at higher probing speeds and greater stylus overtravel, protecting your sensitive workpieces from damage. The IRP40.42 has a repeatability of 2 Sigma 1 μm and can be equipped with styli and stylus balls as small as 0.2 mm.

A robust design means it can operate efficiently under extreme accelerations, high positioning speeds, constant vibrations, hard tool changes and increased temperatures. And its compact size makes it suitable for use within an extremely limited inspection space.

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.
