CT-M Glass-Sealed Hermetic Receptacles, −55 to +200 °C
Glass-to-metal seal · 152 kPa leak-tight · −55 to +200 °C
Hermetic Connectors
Glass-sealed hermetic receptacles that keep gas and moisture out of enclosures — 38999-type, 26482-type, bulkhead feedthrough and miniature designs.
A hermetic connector passes circuits into a sealed enclosure without letting gas or moisture through. In glass-sealed designs 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 feedthroughs 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 conditions can be tested to your requirements.
Compare series
| Series | Sealing | Contacts | Current rating | Temperature | Rated voltage |
|---|---|---|---|---|---|
| CT-M | No leakage at 152 kPa | 2 to 5 | 7.5 A / 13 A | −55 to +200 °C | 250 V |
| K | Leak-tested at 101 kPa | 3 to 61 | 7.5 A | −55 to +125 °C | 500 VAC |
| P-C | ≤ 0.13 kPa/min at 101 kPa | 4 to 31 | 7–200 A | −60 to +60 °C (PR-C +150 °C) | 500 V, 400 Hz |
| ZH28 | Glass-sealed | 3 to 61 | 3–9 A (max. 6–18 A) | −60 to +155 °C (max. 200 °C) | 400–700 V |

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.
