Description

The ITP Straight Stylus Type A with Ruby Ball is a precision probing accessory built for metrology professionals who need dependable, repeatable contact in everyday measurements. With a rigid carbide stem and a high-quality ruby ball, it delivers stable performance across a range of tip sizes and applications.

  • Model: Type A straight stylus, THM203003051
  • Thread: M2 thread on the top for secure mounting in compatible probe heads
  • Overall length: 51.5 mm from tip to thread
  • Material: Carbide stem for exceptional rigidity and dimensional stability
  • Ball tip: Ruby ball performs precise, wear-resistant contact; sizes available from Ø0.5 mm to Ø5.0 mm
  • Tip size range: Standard ruby balls Ø0.5–Ø5.0 mm; additional sizes available on request
  • Design: Straight configuration designed for straightforward probing geometry

Designed for daily use in measurement and inspection tasks, this stylus offers consistent contact quality and long-term reliability. The carbide stem minimizes deflection under load, while the ruby ball provides a smooth, repeatable touch point that resists wear. If your setup requires a different ball diameter, you can request additional sizes via the configurator or by email to ensure a perfect match with your fixtures and probes.
