Telephone Plugs & Jacks

Telephone Plugs & Jacks from Amphenol Military & Aerospace’s Nexus division provide durable audio interconnects built to meet the MIL‑DTL‑9117 military specification. These connectors form the standard interface for telephone‑style communication circuits used in airborne, ground, and industrial headset systems where dependable operation is critical.

Design and Performance

The connectors incorporate environment‑resisting construction and full shielding continuity for EMI/RFI protection. Low‑level circuit capability supports sensitive microphone and control lines, while high cross‑talk resistance ensures signal isolation across multi‑contact configurations. Contacts and housing materials are selected for corrosion resistance and mechanical endurance under vibration and temperature extremes common to military platforms.

Configurations and Options

• Rugged telephone plug and jack formats qualified to MIL‑DTL‑9117
• Multiple mounting and panel styles for equipment or cable applications
• Optional switch functions or auxiliary contacts for push‑to‑talk or signal routing
• Compatible with standard headset and intercom cable assemblies

Typical Applications

• Helmet and headset audio connections for aircrew and vehicle crews
• Portable field communication systems and control boxes
• Maintenance, training, and simulation audio equipment
• Industrial intercom and annunciator systems requiring rugged connectors

Integration Considerations

Telephone Plugs & Jacks interface directly with compatible microphone and earphone circuits, simplifying installation and field maintenance. The MIL‑DTL‑9117 standard ensures interchangeability across qualified suppliers and long‑term availability through defense procurement channels. Engineers selecting these connectors should consider mating requirements, switch functions, and environmental sealing needs aligned with system specifications.
