The IRP40.42 infrared touch probe was specifically developed to measure delicate materials and intricate workpiece geometries in challenging machine tool environments. Designed by Hexagon, the IRP40.42 is a highly versatile touch trigger probe that enables quick and reproducible measurements on coordinate measuring equipment. It also incorporates the advantages of the IRP40.02 touch probe.
Even when probing at increased speeds and with extended stylus overtravel, the trigger forces of the IRP40.42 remain consistently low, preventing any potential damage to sensitive workpieces. This probe can accommodate styli and stylus balls as small as 0.2 mm and boasts a repeatability of 2 Sigma at 1 μm. Additionally, the robust design effectively withstands extreme accelerations, high positioning speeds, continuous vibrations, harsh tool changes, and elevated temperatures.
Features & Benefits
- Consistently Low Probing Forces
The IRP40.42 was specifically designed to measure the geometries of thin, delicate workpieces. Its advanced technology enables high-speed measurements while ensuring minimal contact forces. - Designed for Precision in Small Areas
The measuring device can accommodate styli and measuring spheres as small as Ø 0.2 mm, making it capable of measuring in previously inaccessible locations, even in confined spaces. - Sturdy and Long-Lasting
Each mechanical component is engineered to withstand the demanding conditions typical of machine tools and is protected under the IP68 standard. The probe can endure extreme acceleration, high positioning speeds, continuous vibrations, severe tool changes, and high temperatures. - Innovative HDR+ Infrared Transmission Technology
The HDR+ infrared transmission technology ensures that only the system’s own signals are processed for optimal accuracy.
