Description
The M4 series is a subminiature RF interface designed to meet the extreme density and reliability requirements of modern digital telecommunications. This female (jack) variant is specifically calibrated for BT3002 (Type 2002) cable, the industry-standard 75-Ohm coaxial cable used for E1, E3, and DS3 signal transmission. The M4 interface distinguishes itself with a threaded coupling mechanism, providing superior mechanical stability and vibration resistance compared to push-pull connectors, ensuring 100% uptime in mission-critical environments.
This connector utilizes a professional dual-crimp termination system for both the center pin and the outer ferrule. This ensures a gas-tight mechanical bond that maintains strict 75-Ohm impedance and provides exceptional pull-off resistance. Manufactured with a gold-plated brass body and premium PTFE (Teflon) insulation, it delivers outstanding signal integrity and low return loss up to 3 GHz. The robust construction protects sensitive digital data streams from electromagnetic interference (EMI) and signal jitter in congested exchange environments.
Key Technical Advantages
