Description
The M4 series is a specialized subminiature RF interface designed to meet the rigorous density and reliability requirements of modern digital telecommunications. This male (plug) variant is specifically calibrated for BT3002 (Type 2002) cable, the industry-standard 75-Ohm coaxial cable used for high-capacity E1, E3, and DS3 signal transmission. The M4 interface is highly regarded for its threaded coupling mechanism, which provides superior mechanical stability and vibration resistance compared to push-pull alternatives, ensuring a secure connection in mission-critical environments.
This connector utilizes a high-reliability 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—crucial for maintaining signal integrity in congested rack environments. Manufactured with a gold-plated brass body and premium PTFE (Teflon) insulation, it delivers exceptional signal integrity and low return loss, protecting sensitive digital data streams from electromagnetic interference (EMI) and signal jitter.
Key Technical Advantages
