Amphe-Lite Connector Series


Commercial 38999, Series III Type Composite Connectors

The Amphe-Lite Connector Series is designed for communications equipment manufacturers with signal, power, RF or fiber optic interconnect requirements in harsh environments such as communication towers, outdoor and rooftop applications. This lightweight commercial 38999, Series III type composite connector series is ideal for communications equipment, manufacturing process control and medical equipment.

The Amphe-Lite offers the highest performance capabilities for severe environment applications, and yet is cost effective enough for general duty and non-environmental applications.

Designed for Performance

Numerous advantages in performance capability are designed into the Amphenol(r) Amphe-Lite Connector. A positive shoulder to shoulder coupling design, grounding fingers, and electroless nickel plating provide superior EMI shielding capability of 65 dB minimum at 10 GHz. This EMI shielding capability exceeds MIL-DTL-38999 Series III requirements.These capabilities along with a 125°C temperature rating and superior moisture sealing protection provide the user with a connector that can withstand the most rigorous application.


  • Service Class F Amphe-Lite connectors provide excellent EMI shielding and grounding through electroless nickel plating and spring grounding rings. Environmental sealing is ensured with interfacial seals to prevent contact corrosion. Composite shells are completely immune to corrosion problems.
  • Service Class X provides a non-conductive finish when EMI shielding is not a criteria. Composite shells resist severe corrosion, and provide plating endurance from salt spray exposure for a minimum of 2000 hours.
  • Completely mates in one 360-degree turn of the coupling nut to provide the fastest and easiest equipment assembly and maintenance possible.
  • Acme threads provide coupling durability. Thicker wall sections and a greater coupling surface area improve strength and shock resistance. Blunting of the thread on both the coupling nut and receptacle eliminates cross coupling.


  • Conductive and non-conductive finish options are available.
  • Circuit protection with filter contacts or surge arresting devices are available.
  • Fiber optics, extended life and shielded coaxial contacts can be specified in Amphe-Lite connectors.
  • Ground plane versions of the Amphe-Lite can be specified for use with coaxial and triaxial contacts. Twinax and power contacts can also be specified in the Amphe-Lite.
  • Selectively plated contacts are available
  • High decoupling option is available for high vibration applications.
