Description

The ITP Straight Stylus – Type A with Ruby Ball is a precision probing accessory designed for metrology and everyday inspection tasks. It's built for reliability and consistent contact, making it ideal for technicians and engineers who need rigid performance from a compact probing tip.

  • Part number: THM502010031
  • Thread size: M5 threaded connection for secure mounting
  • Overall length: 31 mm from base to tip
  • Stem material: Carbide for extreme rigidity and durability
  • Tip material: Ruby ball, high-quality for smooth, low-wear contact
  • Tip sizes: Ruby balls available from Ø0.7 mm to Ø3.0 mm
  • Custom sizing: Other ruby ball sizes can be requested via the configurator or by email
  • Configuration: Type A straight stylus

This straight stylus delivers repeatable measurements with a rigid carbide stem that minimizes deflection during probing. The ruby ball tip provides precise, consistent contact across a range of surface finishes, reducing wear on both the tip and the workpiece. Its compact 31 mm length and standard M5 thread integrate smoothly with most probe systems, helping you streamline setup and speed up inspection cycles. If your application requires a non-standard ball diameter, you can request a custom ruby ball size to match feature size and measurement strategy, ensuring you capture accurate data every time.
