Description
The SMB Female Bulkhead Crimp Connector for BT3002 is a specialized RF interface tailored for the European telecommunications industry and high-speed digital transmission systems. BT3002 cable is a high-performance 75-Ohm coaxial line widely used in E1/T1/E3/T3 telephony networks and data exchanges. This connector features a “Bulkhead” configuration with a threaded outer body, hex nut, and lock washer, allowing it to be securely mounted through a chassis or panel to create a permanent, grounded feedthrough point.
Unlike the common 50-Ohm SMB, this version is precision-matched to the 75-Ohm impedance requirements of BT3002 to ensure minimal signal reflection and low return loss at digital transmission frequencies. It utilizes a snap-on coupling mechanism for fast, tool-free mating, making it ideal for the high-density environment of distribution racks. The connector body is manufactured from high-grade brass with gold plating on the contact surfaces, ensuring superior conductivity and long-term protection against corrosion in temperature-controlled equipment rooms and data centers.
Key Technical Advantages
-
BT3002 Precision Calibration: Specifically designed to fit the 75-Ohm geometry and 3.55mm outer diameter of BT3002 (Type 2002) cable, ensuring optimal signal integrity for telecommunications.
-
Stable Panel Mounting: The bulkhead design with integrated D-flat prevents rotation within the chassis cutout, providing a rigid and reliable connection point that withstands cable pulling.
-
Rapid Snap-On Coupling: Facilitates immediate “click” mating and unmating, which is essential for efficient patching and maintenance in crowded digital distribution frames.
-
75-Ohm Impedance Matched: Engineered to prevent impedance mismatches in digital telephony and high-speed data circuits, maintaining high-quality transmission over long cable runs.
-
Corrosion-Resistant Gold Plating: Premium gold-over-nickel finish on critical contact areas ensures low contact resistance across hundreds of mating cycles.
Key Features
