Description
The ITP Straight Stylus Type A with Ruby Ball is a precision probing accessory designed for metrology professionals who need a lightweight, rigid long-reach stylus. Built for accurate, repeatable contact, it combines a carbon fiber stem with a hard ruby ball tip for dependable performance in tight measurement setups.
- Overall length: 22.5 mm from base to tip for compact yet extended reach in challenging measurement scenarios.
- Thread: M5 threaded connection ensures secure mounting in compatible probing systems.
- Material: Carbon fiber stem delivering a superior stiffness-to-weight ratio for high rigidity and minimal deflection.
- Probe tip: Ruby ball tip available in diameters from Ø3.0 mm to Ø12.0 mm for consistent, precise contact.
- Design focus: Straight stylus optimized for long-length applications where stability and quick responsiveness matter.
- Customization: Other dimensions can be requested via the configurator or by email to match specific inspection needs.
This stylus is ideal for measurements requiring a low-mass probe with a rigid, stable axis—reducing inertia and improving data repeatability on delicate features, edges, and small bores. The ruby ball’s hardness and surface finish provide durable, repeatable contact across repeated cycles, while the carbon fiber stem keeps overall weight down for faster probe response. Use it in precision inspection tasks, where reliable contact and accurate results matter most, and tailor the dimensions as needed through the configurator or direct inquiry.
