SMZ M BH PCB MOUNT SOLDER

Description

The SMZ Male (Plug) Bulkhead PCB Mount Solder Connector is a specialized 75-Ohm RF interface designed to bridge the gap between internal PCB circuitry and external cable assemblies. Widely recognized as the BT43 connector, the SMZ series is the robust 75-Ohm evolution of the SMB design, specifically sized for the rigorous demands of E1, E3, and DS3 digital transmission. The bulkhead configuration includes a threaded outer body with a nut and washer, allowing the connector to be secured through an equipment panel or chassis while the solder pins are integrated directly into the printed circuit board.

This vertical-mount connector is designed for through-hole soldering, providing a high-strength mechanical bond and a stable electrical path. It utilizes a snap-on coupling mechanism for the external interface, ensuring a secure “click-lock” mating that is vibration-resistant and easy to manage in high-density rack environments. Manufactured with a gold-plated brass body and premium PTFE (Teflon) insulation, it delivers exceptional signal integrity and low return loss from DC up to 2 GHz, ensuring superior performance in mission-critical telecommunications infrastructure.

Key Technical Advantages

• Integrated Bulkhead Design: Allows the PCB-mounted connector to serve as a chassis interface, eliminating the need for internal jumper cables and reducing signal loss.

• 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, ensuring constant contact in active exchange environments.

• Robust PCB Grounding: The multi-leg through-hole design provides superior structural stability, protecting the solder joints from the mechanical stress of panel mounting and frequent mating cycles.

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