Description
The ITP Straight Styli - Type A with Ruby Ball is a precision probing stylus designed for metrology, inspection, and assembly tasks. It combines a lightweight, rigid ceramic shaft with a high-quality ruby ball to deliver reliable, repeatable contact in everyday use.
- Tip type: Ruby ball tip (Ø6.0 mm to Ø10.0 mm options) provides a smooth, repeatable contact surface for precise measurements.
- Stem material: High-performance ceramic shaft offers low weight and exceptional rigidity to minimize deflection during probing.
- Overall length: 128.5 mm to reach tight spaces while maintaining comfortable control.
- Threaded mount: M4 thread enables secure attachment to compatible probes and stylus holders.
- Special feature: Holder with spanner width SW5,5 for a stable, easy-to-service connection.
- Custom sizing: Other ruby-ball sizes can be requested via the configurator or by e-mail.
This straight stylus is well suited for routine measurement, calibration, and alignment tasks where consistent contact geometry matters. The combination of a light, rigid ceramic shaft and a ruby ball tip supports accurate readings, reduced tip wear, and dependable performance across everyday use. When you need a tailored touch, you can request alternative ruby-ball sizes through the configurator or by email.
