XAVAC D-Sub Feedthroughs

Positronic Xavac connectors are hermetic D-sub feedthrough connectors for space and / or industrial vacuum applications.

Both sides of the d-sub feedthrough contain four threaded mounting holes, an o-ring groove and fixed female jackscrews. Consequently this allows either side of the connector to be mounted toward the vacuum, therefore giving the customer the ultimate in flexibility.

Our Xavac D-sub feedthroughs are filled with an epoxy resin making them far more resilient to vibration, shock and damage compared to glass ceramic alternatives.

The D-Sub feedthroughs are available in 9, 15, 25, 37 and 50 way and also high density d-sub feedthroughs in 15, 26, 44, 62 and 78 way.

Most importantly, all Xavac series connectors are 100% leak tested after fabrication. XAVAC® series connectors utilize precision machined contacts and are therefore strong and durable.  The materials and finishes, as well as the technical characteristics of the XAVAC® series connectors conform to MIL-DTL-24308,Goddard and the SPACE-D32 specifications.

In conclusion, the Xavac connectors are arguably the best hermetic d-sub feedthrough’s on the market.  In addition, we carry stock of these connectors and as a result our customers don’t have to contend with long lead times.
