The MS27467T21B35S from Amphenol is MIL-DTL-38999 Series I straight plug with 79 contacts. MIL-DTL-38999 Series I connectors are available in a wide range of shell materials and finishes with 48, 500 and 1000 hour salt spray plating exposure. These connectors offer high density contact arrangements in a miniature circular shell and combines high coupling durability. It has an improved sealing around each contact to prevent electrolytic erosion. These connectors are available in 9 shell size from 9 to 25 and are designed to withstand extreme shock, exposure and vibration.

The PT06E14-19PX-SR from Amphenol is PT series, MIL-DTL-26482 series I equivalent straight plug with 19 contacts. The PT series miniature cylindrical connectors offer high density contact arrangements in a circular shell with salt spray exposure of 48hour, 500hour. These connectors have 5 key/keyway polarization with 3 point bayonet lock coupling for positive mating with no chance of cross plugging. Spring tension provided by a wave washer in the coupling nut ensures maintenance of interfacial seal between mating halves. Both the insert and main joint gasket are moulded from resilient neoprene insulator. These connectors are designed for harsh environments and have well-proven electrical capability to withstand extreme shock, exposure and vibration. The high reliability performance makes PT series connectors ideal for environmental sealing or pressurized applications.

The MIL-DTL-38999 Series I & II high-performance Cylindrical Connector with low-profile 3-point bayonet coupling. It is designed for cable-to-panel I/O applications in military aerospace and other demanding situations. Environmental class plugs and receptacles with high-density insert arrangements – are available with crimp removable contacts, PC tails and solder cups. Glenair manufactures a wide range of environmental class MIL-DTL-38999 type connector including lanyard-release products, composite and specialty metal cable plugs and receptacles and coax contact equipped products. It is also designed for use in pressurized or severe environmental applications. Hermeticity is generally defined as the state or condition of being air or gas tight. In interconnect in dielectric breakdown, corrosion and loss of insulation resistance between conductors. The classic hermetic application is a receptacle feed-through penetrating a pressurized bulkhead or pressurized equipment housing.
