The combination of a carbon fiber stem and a ruby contact point provides a balance of lightness and stiffness, reducing deflection during measurement and improving repeatability. The long reach is particularly advantageous for accessing features located away from the probe holder, while the M5 connection ensures compatibility with a wide range of probing systems. With options to customize ball diameter and other dimensions, this stylus can be tailored to specific inspection tasks, from PCB and connector probing to precision measurements on micro-machined parts.
