Description
The ITP Straight Styli Type T with Ruby Ball is a precision, non-threaded stylus designed for metrology and micro-probing applications. This 22.4 mm overall-length probe combines a tungsten carbide stem with a ruby contact ball for reliable, repeatable measurements, listed under KTM500802022.
- Non-threaded straight design: Enables easy mounting and flexible positioning with compatible clamp holders, reducing setup time.
- Tungsten carbide stem: Offers exceptional rigidity and wear resistance, with options for single- or multi-stepped configurations to match probing needs.
- Ruby ball tip: Precision ruby contact ball available in diameters from 0.2 mm to 5.0 mm, providing low-friction, durable contact.
- 22.4 mm overall length: Compact form factor that fits into tight measurement setups while maintaining robust handling.
- Type T construction: A dedicated variant designed for consistent performance with compatible accessory ecosystems.
- Clamp-ready compatibility: Designed to be used with the appropriate clamp holder for secure, repeatable probing sessions.
- Custom sizes available: Other ruby-ball diameters can be requested via configurator or by email to tailor contact and resolution.
This straight stylus is ideal for tasks that demand precise, repeatable contact without the constraints of threaded options. The tungsten carbide stem preserves dimensional stability under repeated probing, while the ruby ball tip minimizes wear on delicate surfaces and delivers consistent feedback. With a compact 22.4 mm length and clamp-ready design, it supports efficient setup in electronics inspection, micro-machining checks, PCB probing, and profilometry. The ability to choose ball diameters—ranging from 0.2 mm to 5.0 mm—lets you optimize for resolution or contact area based on your measurement needs.
