ITP Straight Styli Type A with Ruby Ball is a precision probing stylus designed for long‑reach measurements in metrology and manufacturing. Built for engineers and technicians who need a lightweight, ultra‑rigid interface for CMM touch probes, this stylus combines a carbon fiber stem with a high‑quality ruby ball for reliable, repeatable contact.
- M5 thread: Compatible with standard probing modules for easy integration into existing setups.
- Overall length: 153 mm, providing extended reach for hard‑to‑access features.
- Carbon fiber stem: Low weight with superior rigidity to minimize deflection during probing.
- Ruby ball head: High‑quality contact surface available in sizes from Ø3.0 mm to Ø12.0 mm for versatile applications.
- Customizable dimensions: Other lengths or ball sizes can be requested via the configurator or by email.
The ruby ball head offers durable, precise contact geometry that helps improve measurement repeatability across scans and measurements. The carbon fiber stem keeps the overall weight down while maintaining stiffness, which is especially beneficial when probing long or complex features. This design is ideal for professionals working with touch probes on long‑reach tasks, whether in aerospace, automotive, or precision manufacturing environments. For projects requiring specific dimensions, you can tailor the stylus to your machine’s probing envelope to ensure optimal performance.
