Description
The SMZ Female (Jack) Crimp Connector for BT3002 is a specialized 75-Ohm RF interface widely utilized in telecommunications infrastructure for E1, E3, and DS3 signal transmission. Often referred to as the BT43 connector, the SMZ series is a larger, more robust version of the SMB interface, specifically designed to meet the rigorous demands of exchange equipment. 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 digital networks.
This connector is precision-calibrated to match the physical and electrical characteristics of BT3002 (Type 2002) cable. 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 in central office environments.
Key Technical Advantages
-
BT3002 Precision Fit: Specifically engineered for the 3.55mm outer diameter and 75-Ohm impedance of BT3002 cable, ensuring minimal signal reflection and low return loss.
-
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.
-
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.
-
Superior EMI/RFI Shielding: The all-metal body and high-quality crimp sleeve provide maximum shielding effectiveness for sensitive digital telephony signals.
-
Industry Standard Compliance: Fully compliant with telecommunications standards for digital signal routing, ensuring universal intermateability with SMZ male (plug) interfaces.
