Description
The C4 series is a high-performance RF interface specifically developed for the rigorous 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 C4 interface is a staple in telecommunications infrastructure, providing a secure and compact connection that allows for maximum port concentration on equipment faceplates and modular hardware.
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 contact 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).
Key Technical Advantages
-
Micro-Cable Precision Fit: Specifically calibrated for the dimensions of LMR100, RG174, and RG316 (approx. 2.5mm–2.8mm OD), ensuring an optimized electrical transition and consistent signal path.
-
75-Ohm System Integrity: Strictly calibrated to eliminate impedance mismatches, preventing bit errors and signal reflections in high-capacity digital circuits.
-
High-Density Footprint: The subminiature design allows for a significantly higher concentration of ports on DDF panels compared to larger 75-Ohm interfaces.
-
Rapid Dual-Crimp Assembly: The industrial-grade crimp design for both the center contact and outer sleeve provides a high-strength, repeatable termination ideal for large-scale infrastructure deployments.
-
Superior Corrosion Protection: Premium gold-over-nickel plating on all critical contact surfaces ensures low contact resistance and long-term durability in professional networking environments.
