Micro-D Glass-Sealed Hermetic Connectors
|
Glenair's Hermetic Micro-D Connectors feature fused
glass insulators to provide an airtight seal. These
connectors are 100% tested to meet a maximum leak
rate of 1 X 10-8 cc's per second of helium. Matched Kovar® Seal. The shells and contacts are machined from Kovar®, an iron-nickel-cobalt alloy which forms a chemical bond with the vitreous glass insulator. The contacts are gold-plated and the shell is nickel-plated. Micro-D Hermetic Connectors General Information |

These Kovar® alloy connectors are available in three styles: solder cup contacts, PC tail contacts or pre-wired and epoxy-sealed. Socket contacts are Kovar® alloy with gold plating. These connectors can be front- or rear-panel mounted. Installation requires soldering, brazing or welding to the bulkhead. Helium leak rate is 1 X 10-9 cc's per second. |
MWDM Hermetic for Rear-Panel Mounting (177-705H and 177-706H) |

Avoid the expense of soldering or welding with this o-ring version. Blind tapped mounting holes and integral jackposts provide easy installation. Three termination options are available: solder cup contacts for #26 AWG or smaller wire, PC tails for rigid or flexible circuit boards, or pre-wired with extended epoxy encapsulation to protect and insulate the solder joints. |
