- Thread: M2 mounting thread for secure integration with compatible probes and measurement systems.
- Overall length: 17 mm profile provides a compact, unobtrusive probing solution for confined fixtures.
- Tip options: Ruby ball tips available from Ø0.2 mm to Ø1.0 mm to match contact profile and feature size.
- Material and construction: Carbide stem delivers high rigidity and durability with a straight design for consistent contact.
- Configuration: Stem can be single- or multi-stepped to suit different probing needs and geometries.
- Customization: Additional sizes can be requested via configurator or by email to fit specific measurement tasks.
- Intended use: Designed for everyday standard probing tasks where reliability and repeatability matter.
This stylus is ideal for tactile probing in micro metrology, helping professionals achieve repeatable contact on small features with minimal deflection. The carbide stem maintains shape under typical probing forces, while the ruby ball tip offers durable, low-wear performance across repeated measurements. With its compact form and flexible tip options, it fits into tight fixtures and diverse measurement scenarios—from fine-feature inspection to routine layout verification—without sacrificing accuracy or consistency.
