Description
The SMZ Male (Plug) Right-Angle PCB Mount Solder Connector is a specialized 75-Ohm RF interface designed for board-level applications where vertical space is limited. Widely recognized as the BT43 connector, the SMZ series is the robust 75-Ohm evolution of the SMB design, specifically optimized for the rigorous demands of E1, E3, and DS3 digital transmission. The 90-degree right-angle configuration allows for horizontal mating, keeping the mated cable assembly parallel to the PCB surface. This is critical for high-density stacking of boards and for use in shallow equipment chassis.
This connector is designed for through-hole soldering, providing a high-strength mechanical bond to the printed circuit board. It utilizes a snap-on coupling mechanism for the interface, ensuring a secure “click-lock” mating that is vibration-resistant and tool-free. Manufactured with a high-grade gold-plated brass body and premium PTFE (Teflon) insulation, it delivers exceptional signal integrity and low return loss from DC up to 2 GHz. Its design ensures a stable electrical path that protects sensitive digital data streams from signal reflection.
Key Technical Advantages
-
Low-Profile 90° Integration: Minimizes the vertical height required on the PCB, allowing for slim enclosure designs and efficient multi-board stacking in equipment racks.
-
75-Ohm System Integrity: Specifically calibrated for telecommunications standards, preventing data errors and signal reflections in high-capacity digital circuits.
-
Vibration-Proof Snap-On Lock: The SMZ (BT43) interface offers a more robust mechanical mating than standard SMB connectors, maintaining constant contact in active exchange environments.
-
Robust Mechanical Stability: The multi-leg through-hole design provides superior structural grounding, protecting the solder joints from the torque and tension of mated cables.
-
