Hermetic Connectors

Glass-sealed and hermetic receptacles that keep gas and moisture out of sealed equipment — 38999-type, 26482-type, bulkhead feed-through and miniature designs.

A hermetic connector passes circuits into a sealed enclosure without letting gas or moisture through. The contacts are fused into the shell with glass, so the connector stays tight even when unmated.

Our range covers 38999-type hermetic receptacles (J599 Series III and GJB599 Series I), 26482-type K receptacles, P-C bulkhead feed-throughs with contacts up to 200 A, small CT-M glass-sealed receptacles to +200 °C, and ZH28 receptacles with up to 61 contacts. Leak rate, pressure and temperature are stated per series; other test conditions are tested to your requirements.

How to choose

Leak rate and pressure

Tell us the pressure differential and leak rate you need; each series page states its test condition.

Mating interface

Choose the series that matches your plug: 38999-type, 26482-type, P-type or ZH23.

Current

Signal contacts from 3 A; P-C feed-throughs carry up to 200 A per contact.

Temperature

CT-M to +200 °C; ZH28 to +155 °C (200 °C maximum); PR-C to +150 °C.

Frequently asked questions

Can you test to my leak-rate requirement?

Yes. Tell us the leak rate, test gas and pressure, and we test to your requirements, including third-party testing on request.

Can hermetic receptacles be customized?

Yes. Contact counts, contact sizes, shell materials and mounting can be customized.
