Description
The ITP Straight Styli Type A with Ruby Ball is a precision probing stylus designed for long‑reach measurement tasks. It delivers light weight and high rigidity, making it ideal for metrology setups where extended length and stable contact matter.
- Product Code: TCM504080102
- Thread: M5 thread for secure attachment to compatible probes and holders
- Overall Length: 102 mm from base to tip for extended reach
- Stem Material: Carbon fiber for exceptional stiffness-to-weight ratio and minimal deflection
- Tip: Ruby ball tip constructed from high-quality ruby, offering a hard, smooth contact surface
- Tip Diameter Options: Available in a range of ruby ball diameters (Ø3.0 mm to Ø12.0 mm) to suit different probing needs
- Customization: Other dimensions can be requested via the configurator or by e-mail
By combining a lightweight carbon fiber stem with a precise ruby ball tip, this stylus minimizes mass at the contact point while maximizing rigidity. That balance reduces deflection during probing, enhances measurement stability, and delivers repeatable results across multiple cycles. The 102 mm reach allows access to features tucked under fixtures or within recessed areas, while the standard M5 thread ensures compatibility with a wide range of metrology equipment. For specialized applications, you can tailor dimensions through the configurator or reach out by email for a custom specification.
