Filtered Audio Connectors

The 164F Series Filtered Audio Connectors from Amphenol Military & Aerospace’s Canadian operation provide rugged, EMI‑protected interconnects for military headset, handset, and intercom equipment. These connectors fully meet or exceed the mechanical, electrical, and environmental requirements of MIL‑DTL‑55116, ensuring interchangeability with standard field communication plugs and receptacles.

Design and Construction

• Available in five‑ and six‑pin layouts compatible with MIL‑DTL‑55116 interfaces.
• Incorporate integrated EMI filtering elements within each contact to reduce conducted and radiated noise on audio lines.
• Feature grounded pins and lightning protection capability for signal integrity under harsh operating conditions.
• Utilize passivated stainless‑steel shells with high‑grade thermoplastic inserts for durability and thermal stability.
• Employ Amphenol’s patented solderless stress‑isolation design that mechanically decouples the contact terminations from cable load, improving vibration endurance and field repairability.

Environmental and Mechanical Performance

• Engineered for full sealing against moisture and contaminants to maintain contact reliability.
• Tested for thermal cycling, mechanical shock, and mating endurance per MIL‑DTL‑55116 criteria.
• Optional materials, plating finishes, and termination styles available to match system‑specific environmental and wiring requirements.

Termination and Integration Options

• Cable‑, wire‑, and board‑mount configurations supported.
• Alternate plating and conductor materials offered for corrosion resistance or weight optimization.
• Value‑added options include bundled harness assemblies and over‑molding for improved EMI/EMP shielding continuity.

Typical Applications

• Handheld and vehicle communication headsets and intercom systems.
• Command‑and‑control consoles, field radios, and tactical audio accessories.
• Systems requiring filtered audio connectors that provide EMI/EMP suppression and long‑life environmental sealing.

The 164F Series serves as a direct filtered enhancement to Amphenol’s MIL‑DTL‑55116 audio connector portfolio, offering electrical noise mitigation without altering mechanical compatibility. Its robust construction and sealed design make it suitable for both new and legacy field communication equipment.
