Coaxial Connector selection primarily depends on the user's application, specification requirements, and the trade-off between cost and performance ratio.
First, consider material selection. The connector body ranges from low-cost zinc alloy and standard brass to stainless steel, which satisfies high-durability demands in extreme environments. For Plug Pin are typically made of brass, while Jack Pin generally utilize beryllium copper—though lower-cost phosphor bronze can serve as an alternative. For the dielectric insulator, PTFE / Teflon is the standard choice, but it can be replaced by more economical materials such as Delrin, PE, or PP.
In terms of manufacturing, CNC lathes represent the baseline equipment for current production. However, transforming a product design into precise CNC programming for each individual component, combined with final dimensional matching, remains the indispensable core requirement for meeting strict specifications.
Second, plating selection is critical. In the industry, plating is often the most significant factor affecting the supply price. Common plating options include Gold, Nickel, and Tri-metal / white bronze / Sucoflex. Ultimately, however, it is the plating thickness that dictates the final cost of the coaxial connector.
Q. We are developing a new project. How should we approach selecting the right coaxial connector?
Ans: There is no absolute standard for selecting a coaxial connector; it primarily depends on your specific application and specification requirements. The core mindset is to achieve the optimal trade-off between cost and performance (Cost/Performance Ratio).
Q. Regarding material selection, what are the key considerations for the connector body and pins?
Ans: Materials directly determine durability and cost. For the connector body, zinc alloy is a low-cost option, brass is the standard choice for general use, and stainless steel is required to meet high-durability demands in extreme environments.
For contacts, the standard choice for plug pins is typically brass. Jack pins generally utilize beryllium copper for its excellent elasticity and conductivity; however, lower-cost phosphor bronze can serve as an alternative if you need to reduce expenses.
Q. How do we choose the right material for the insulator?
Ans: Polytetrafluoroethylene (PTFE, commonly known as Teflon) is the most widespread and stable standard choice in the industry. However, if you are under strict cost-control pressures and the signal requirements allow, more economical materials like Delrin, polyethylene (PE), or polypropylene (PP) can be considered as alternatives.
Q. Aside from materials, does the manufacturing process affect specification performance?
Ans: Absolutely, and it is decisive. Nowadays, utilizing CNC lathes is merely the baseline equipment requirement. What truly creates a technical gap is how engineers transform a product design into precise CNC programming for each individual component, combined with the final dimensional matching. This is the real key to meeting strict specification requirements.
Q. I understand that plating is also highly specialized. Does it significantly impact pricing?
Ans: Plating is often the most critical factor affecting the supply price in the industry. Common plating materials include gold, nickel, and tri-metal (white bronze/Sucoflex). However, keep in mind that the material is just the baseline; the plating thickness is the ultimate metric that dictates the final quoted cost.
