In large-scale mass production, component cost control is often crucial. If your project has budget and cost considerations, S-Conn provides an excellent value-engineering (Cost-Down) alternative: BNC connectors featuring die-cast Zinc Alloy Shells.
As a reliable alternative to traditional CNC-machined brass shells, our zinc alloy solution significantly lowers your procurement costs without sacrificing system electrical performance.
Key Advantages of Zinc Alloy Shells:
Significant Cost Reduction (Top Choice for Cost-Down)
Utilizes a high-efficiency die-casting process to drastically reduce material waste and cycle times—making it the optimal solution for lowering BOM costs in mass production.
Reliable Durability & Shielding
Delivers solid mechanical strength combined with high-quality nickel plating, providing excellent corrosion resistance and stable RF grounding and shielding performance.
Smooth Bayonet Coupling
Precise tooling controls tolerances to deliver a smooth push-and-twist locking feel comparable to standard components.
