Description
The ITP Straight Styli - Type A with Ruby Ball is a precision probing stylus designed for production environments, delivering reliable, repeatable measurements in metrology and assembly workflows.
- Overall length: 63.5 mm from tip to base, providing comfortable reach in tight workspaces.
- Thread: M5 threaded connection for secure, compatible mounting in standard tooling and probing systems.
- Ceramic stem: lightweight yet highly rigid to minimize deflection and maintain measurement stability during contact.
- Ruby ball tip: premium ruby ball at the end, known for wear resistance and smooth contact; uses ruby balls in the Ø5.0 mm to Ø10.0 mm range.
- Material quality: high-performance ceramic stem engineered for durability in demanding production environments.
- Customizable dimensions: if you need alternate lengths or details, other dimensions can be requested via the configurator or by email.
Designed to deliver consistent, repeatable touch-probing results, this stylus reduces measurement drift and tip wear for long-lasting accuracy in quality checks, fixture alignment, and automation tasks. The combination of a rigid ceramic stem and a hard ruby ball provides a reliable contact surface that stands up to frequent use in production settings. With its 63.5 mm reach and standard M5 thread, it integrates smoothly into existing probing stations and tooling setups. Ideal for precision inspection, process monitoring, and repeatability-critical applications, the ITP Straight Styli - Type A helps you achieve dependable results with minimal downtime. For non-standard sizing, request alternatives through the configurator or by contacting us via email.
