MIL-DTL-5898 defines rugged, flexible cable constructions used primarily for microphone and headset extension cords in military aircraft and other demanding communications environments. These cables are designed to maintain signal integrity and durability under repeated handling and harsh operating conditions.

Typical Construction Elements

MIL-DTL-5898 cables generally incorporate:

  • Conductors: Fatigue-resistant copper alloy conductors
  • Insulation: Polyethylene for stable electrical performance
  • Shielding: Served fabric shielding on selected constructions
  • Jacket: Abrasion-resistant, flame-retardant polyurethane thermoplastic elastomer

This construction balances flexibility, noise control, and mechanical durability.

Performance Characteristics

  • High fatigue resistance under repeated flexing
  • Durable jackets for flight-line and field use
  • Consistent signal performance in dynamic environments

These attributes support reliable use in both military and demanding commercial applications.

Variations and Modifications

Available variations may include:

  • Non-halogen or non-flame-retardant jackets
  • High-gloss finishes for commercial use
  • Application-specific construction modifications

Typical Applications

  • Aircraft headset and microphone cords
  • Ground support and flight-line communications
  • Emergency and public safety systems
