Description
The C4 series is a specialized RF interface widely utilized in telecommunications infrastructure for high-density digital signal routing. This female (jack) variant is specifically calibrated for BT3002 (Type 2002) coaxial cable—the industry-standard 75-Ohm cable used for E1, E3, and DS3 digital transmission. The C4 interface is highly regarded in the telephony sector for its compact size and reliable mating characteristics, allowing for a significant concentration of ports in modular exchange hardware and patching panels.
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, which is critical for maintaining 100% uptime in mission-critical networks. Manufactured with a gold-plated brass body and premium PTFE (Teflon) insulation, it delivers outstanding signal integrity and protects sensitive digital data streams from electromagnetic interference (EMI) and signal jitter in congested exchange environments.
Key Technical Advantages
-
High-Density Infrastructure Ready: The subminiature footprint of the C4 interface allows for maximum port density on DDF panels and modular switching equipment.
-
BT3002 Precision Matching: Specifically engineered for the 0.31mm center conductor and dimensions of Type 2002 cable, ensuring an optimized electrical transition and consistent signal path.
