Microphone Plugs & Jacks

Amphenol Military & Aerospace offers microphone plugs and jacks manufactured by Amphenol Nexus Technologies, a long‑established supplier of ruggedized connectors for communication headsets and control equipment. These audio interconnects serve as the standard interface across military helmet systems, vehicular intercoms, and industrial communication headsets that demand mechanical reliability and environmental endurance.

Design and Construction

The microphone plug and jack range includes 2‑pin and 3‑pin configurations designed for signal transmission between microphones, earphones, and control units. Each connector incorporates a locking mechanism that prevents accidental disengagement under vibration or movement. Components feature durable contact plating, insulated inserts, and mechanical strain‑relief to maintain connectivity under mechanical shock and humidity exposure typical of field operations.

Variants and Options

• 2‑pin mono microphone connectors for single‑channel circuits
• 3‑pin balanced audio connectors supporting duplex circuits
• Selector‑switch models integrating push‑to‑talk or channel‑select functionality
• Compatible mating with other standard Amphenol Nexus communication connector families

Applications

These microphone plugs and jacks are used in communication headsets, military aviation and ground‑crew helmets, vehicular intercom stations, and related ruggedized systems requiring waterproof and vibration‑resistant audio connectors. Their environmental sealing and mechanical retention make them suitable for defense, emergency response, and industrial communication platforms.

Integration Guidance

Connectors are typically panel‑ or cable‑mounted and may be specified with solder‑cup or crimp‑sleeve contacts for dependable termination. Engineers should select pin count and locking style based on equipment interface standards and required circuit isolation between microphone, earphone, and ground paths. Amphenol Nexus devices are recognized for consistent mating compatibility and service longevity across generations of tactical communication products.
