A 6×50 mm closed-end probe sleeve in stainless steel – the workhorse size for NTC and PT100 assemblies. The closed end is drawn with a full radius, so the element never contacts a crease, and the bore is smooth for even contact transfer.
Function and Design
The closed-end probe sleeve is small in the bill of materials and large in the warranty claim when it goes wrong. Tolerances that matter are confirmed with capability data before the closed-end probe sleeve is quoted.
What Makes It Work
- The closed end is formed, not welded – a smooth radius with no heat-affected zone to corrode or crack.
- Being stainless, it handles washdown, humidity and process media without a coating that can chip.
- Family page: your print sets dimensions, features and tolerances.
- Material: Standard stock covers stainless steel (304 / 316); equivalents are feasibility-checked against your print before quoting.
- Process: deep drawn closed-end probe sleeve body with in-die piercing, sealing faces finished by turning.
- Finish: No catalogue finish: the closed-end probe sleeve surface is agreed on the drawing and confirmed at sample approval.
- Size: Closed-end probe sleeve size to drawing, with the agreed version governing every later batch.
- Custom: The closed-end probe sleeve is made to print – low MOQ on standard items, volume pricing on repeats.
Where It Is Used
In service you will find this part in HVAC and refrigeration sensors, industrial process instrumentation, household appliance thermometers.
Our Production Advantage
Drawn shells are stress-relieved before critical faces are machined. Any deviation on a sealing face is corrected at the machine, not after plating.
