SMZ F CRIMP for LMR100/RG174/RG316 Cable

Description

The SMZ Female (Jack) Crimp Connector is a specialized 75-Ohm RF interface widely utilized in telecommunications infrastructure for E1, E3, and DS3 digital signal transmission. Often referred to as the BT43 connector, the SMZ series is a larger, more robust evolution of the SMB interface, specifically designed to meet the rigorous demands of exchange equipment and Digital Distribution Frames (DDF). This crimp-style variant is engineered for high-volume, consistent assembly, providing a secure mechanical and electrical bond that is essential for maintaining signal integrity across high-speed networks.

This connector is precision-calibrated to match the physical characteristics of micro-diameter 75-Ohm and 50-Ohm cables including LMR100, the flexible RG174, and the high-temperature RG316. It utilizes a dual-crimp termination system for both the center contact and the outer ferrule, ensuring an industrial-strength bond that resists cable pull-off and vibration. The snap-on coupling mechanism provides a secure, tool-free “click-lock” connection, allowing for rapid patching in high-density environments. Manufactured with a high-grade gold-plated brass body and premium PTFE (Teflon) insulation, it delivers superior electrical performance and long-term protection against corrosion.

Key Technical Advantages

• Universal Micro-Cable Precision: Specifically engineered for the dimensions of LMR100, RG174, and RG316 (approx. 2.5mm–2.8mm OD), ensuring a secure mechanical grip and optimized signal transition.

• 75-Ohm System Integrity: Engineered to maintain the critical impedance matching required for telecommunications standards, preventing data errors and signal reflections in digital circuits.

• Robust Snap-On Interface: The SMZ (BT43) mechanism offers a more substantial mechanical lock than standard SMB connectors, making it ideal for frequent mating cycles in DDF environments.

• High-Reliability Crimp Termination: The dual-crimp design provides a permanent, gas-tight mechanical connection that is faster and more consistent than soldering in large-scale installations.

• Superior Corrosion Protection: Premium gold-over-nickel plating on critical contact surfaces ensures low contact resistance and long-term durability in professional infrastructure.

Key Features
