Stainless probe needles with brass tips – stainless shaft for stiffness, brass tip where contact resistance matters. Tip and shaft are joined and staked, then the tip diameter is gauged for contact consistency.
Function and Design
Needle parts live at the extreme of slenderness, where straightness beats everything – a bent needle ruins the assembly it serves. Ours are drawn or ground, stress-relieved, and checked for runout along the full length before packing.
Key Features
- Stainless stands up to washdown, humidity and process media – no plating to fail.
- Volume pricing is supported by in-house tooling and long-run press and machining capacity.
- Every piece is deburred and cleaned ahead of packing.
- Material: stainless steel (304 / 316) for the probe needle, with material certs issued together with the dimensional report.
- Process: bar-fed CNC turning, with the probe needle milled in the same clamping.
- Finish: No catalogue finish: the probe needle surface is agreed on the drawing and confirmed at sample approval.
- Size: Final dimensions of the probe needle to your drawing; this page shows the family, your version is quoted from the print.
- Custom: OEM/ODM to drawing; free samples of the probe needle and a manufacturability review before tooling.
Where It Is Used
It earns its place in automation and robotics hardware, instrumentation fittings, electronic and telecom enclosures.
Why Source It From Aunov
The probe needle is accepted on measured microns rather than appearance. Sampling runs through the batch, so a shift in the tool shows up before the last parts are made.
