Description
The ITP Straight Styli - Type A with Ruby Ball is a high-precision probing stylus designed for metrology and micro-assembly. It pairs a light, ultra-rigid carbon fiber stem with a durable ruby contact ball to deliver dependable, repeatable measurements in tight tolerances.
- Model and geometry: Straight stylus with 33.5 mm overall length tailored for long-reach probing applications.
- Thread: M5 coupling for easy integration with standard probing systems.
- Stem material: Carbon fiber for exceptionally low weight and high rigidity, reducing deflection during contact.
- Contact ball: High-quality ruby ball, available in diameters from Ø3.0 mm to Ø12.0 mm to match precision requirements.
- Design purpose: Ideal for styli with excess length, providing stable performance without compromising accuracy.
- Custom dimensions: Other dimensions can be requested via the configurator or by e-mail.
- Product code: TCM504011033 for easy ordering and reference.
With its combination of a lightweight carbon fiber stem and a robust ruby ball, this stylus minimizes measurement drift and mechanical load on the probe. The Type A configuration is well-suited for demanding metrology tasks, including coordinate measurement, fixture alignment, and high-precision inspection, where repeatable contact and long tool life are essential. For users needing alternative ball sizes or lengths, additional dimensions are available on request to fit specific setups and probes.
