High Density Sub-Ds

Compared to a Standard Sub-D, High Density Sub-Ds have:

  • Lower voltage rating: 375V DC
  • Lower current rating: 2 Amps/pin
  • Same temperature range: -269C to 450C
  • Same pressure at 20°C: 1350 PSIG (15 Pin)
  • Different pin diameter: .030" [0.76mm]
  • Different pin counts: 15, 26, 44, 62, 78

Push-Pull Connectors 

Some advantages of the push-pull coaxial connectors are:

  • Ideal for applications which require frequent plug removal
  • Very simple, safe plug connectivity and disconnecting
  • Flexible design - comes in all standard flanges and weldable configurations


Sub-Cs are higher density multi-pin connectors with plugs in smaller flanges (1.33”CF), essentially providing all the capability of a Sub-D in a smaller version.

Power Boots

The new and improved power boots offer the following benefits:

  • Lower lead times - this has come down from 20+ weeks to less than 6 weeks if not in stock
  • Custom lengths are available
  • Lower costs

Updated Mil-C-26482s

The original design for Mil-C-26482 Connectors had a single glass-ceramic perform for all pins which would produce inconsistent results when sealing. However, in the new design:

  • Each pin has its own small preform which has led to very consistent results
  • It's easy to plan deliveries accurately
  • All ratings are identical, parts have been fully tested and perform the same if not better on all ratings

Updated Spade Type Thermocouples

The Spade style contacts and air-side thermocouple plugs that CeramTec has historically used on Thermocouples have been discontinued.

CeramTec has found a replacement manufacturer for the spade contacts and plugs, which they consider a direct replacement – the components are interchangeable.

All thermocouple feedthrough part numbers will remain the same, but the replacement plug numbers will change from 8151-XX to 25735-XX.

High Power Mil-C-5015 Connectors & Power Ds

A high powered multi-pin connector in a small footprint, this product offers:

  • Standard air-side connectivity (Mil-C-5015)
  • Simplified Sub-C style Vacuum side Connectivity
  • Copper-cored pins for higher current carrying capabilities (up to 20 Amps)
  • Glass-ceramic Seals for simplified design & high pressure capabilities
  • 3, 4, 6, 10, 20 & 35 pin versions
