Description
The KMX3 series is a high-performance, subminiature RF interface specifically developed for the high-density requirements of modern digital telephony. This male (plug) variant is optimized for micro-diameter cables, including the low-loss LMR100, flexible RG174, and high-temperature RG316. The KMX3 interface is widely utilized in telecommunications for its space-saving snap-on coupling mechanism, which allows for rapid, tool-free mating and unmating while maintaining excellent electrical stability in high-density rack environments.
Maintaining a strict 75-Ohm impedance, this connector is essential for ensuring signal transparency in high-speed digital circuits, such as E1, E3, and DS3 telephony standards. It utilizes a professional dual-crimp termination system for both the center conductor and the outer ferrule, providing a gas-tight mechanical bond that resists vibration and cable strain. Manufactured with a gold-plated brass body and premium PTFE (Teflon) insulation, it delivers superior shielding effectiveness and low return loss, protecting sensitive digital data streams from electromagnetic interference (EMI).
