FEATURES

AMPHENOL AMPHE-LITE™ FEATURES

  • High-Reliability
    Amphe-Lite connectors perform flawlessly under wide temperature ranges and in high vibrations and are resistant to a vast array of contaminants. Visual confirmation of mating is accomplished by the plug coupling nut covering a red band on the mating shell.

  • Outstanding EMI-Shielding Protection
    These connectors provide excellent signal integrity due to the shielded mating system that utilizes 360-degree shell grounding fingers, providing protection of up to 50 dB minimum - 100Mhz to 10GHz.

  • Operates at Extreme Temperatures
    These connectors will operate in temperatures from -67°F up to 320°F (-55°C up to +150°C).

  • High-Density Connectors
    If space is at a premium, Amphe-Lite offers up to 128 contacts per connector. Ideally suited for digital electronics used on fly-by wire aircraft, advanced robotics, and critical industrial equipment.

  • Self-Locking Container Systems
    Self-locking coupling nuts and self-locking endbell accessory hardware provide the best performance for threaded connectors in high-vibration applications.

  • Contact Protection
    Amphe-Lite connectors are designed to be scoop-proof. Pin contacts are recessed to prevent contact damage and contact shorting when connector halves are mated.

  • Approvals
    Amphe-Lite is UL-recognized, File E115497
    RoHS Compliant
