Description
ITP Straight Stylus Type A with Ruby Ball is a precision, M4-threaded probing stylus designed for everyday measurement tasks. With a 48 mm overall length and a ceramic, lightweight stem, it delivers reliable rigidity and smooth contact for consistent data capture in metrology setups.
- Thread: M4 thread compatibility for common probing systems.
- Overall Length: 48 mm, compact form for tight instrument spaces.
- Stem Material: High-performance ceramic offers low weight and high rigidity to minimize deflection.
- Ruby Ball Diameter: Premium ruby ball available in Ø6.0 mm to Ø10.0 mm for different contact profiles.
- Holder: Integrated holder with spanner width SW5,5 for secure mounting and easy exchange.
- Customization: Other sizes can be requested via the configurator or by e-mail.
This stylus is ideal for engineers and quality labs seeking precise, repeatable touch measurements in CMM setups, coordinate measurement tasks, and precision inspection. The ceramic stem keeps weight to a minimum, reducing inertia during contact and improving response, while the ruby ball provides durable, wear-resistant contact with the workpiece. The SW5,5 holder simplifies installation and tool changes, helping you minimize downtime. If your process requires a different ball size or length, additional options are available via the configurator or by email.
