Product Overview
The MN-C-41M is a premium 4.3-10 Male RF Coaxial connector engineered for the modern wireless market. Ideal for DAS, Base Stations, and Wireless Infrastructure, it provides the same robust reliability as 7/16 DIN connectors but in a 40% lighter and significantly smaller footprint. Its unique design separates electrical and mechanical components, ensuring stable PIM performance (≤-150dBc) regardless of the coupling torque. With silver-plated contacts and Tri-Alloy plated bodies, it offers superior conductivity and exceptional corrosion resistance.

Frequently Asked Questions
- Q1: What are the main benefits of using 4.3-10 connectors over 7/16 DIN?
- A: The 4.3-10 interface is significantly smaller and up to 40% lighter, making it perfect for high-density applications. Crucially, it provides much more stable PIM performance that is less sensitive to coupling torque compared to the 7/16 series.
- Q2: Why is the -150dBc PIM rating significant for DAS and base stations?
- A: PIM (Passive Intermodulation) interference can severely limit network capacity. A rating of ≤-150dBc ensures a clean signal path, which is essential for maintaining the high data speeds and reliability required by 4G LTE and 5G wireless infrastructure.
- Q3: How does the separation of electrical and mechanical components improve installation?
- A: In traditional connectors, the electrical contact pressure depends on the tightening torque. In the 4.3-10 design, these are independent, meaning you get excellent electrical performance even if the connector is only hand-tightened, simplifying field installation.
- Q4: What protection does the Tri-Alloy (White Bronze) plating provide?
- A: Tri-Alloy plating is non-magnetic, which is vital for low PIM. It also provides a high level of conductivity and excellent resistance to corrosion and wear, making it ideal for long-term outdoor deployment.
- Q5: Is this connector compatible with existing N-type or DIN 7/16 equipment?
- A: No, 4.3-10 is a unique interface standard (IEC 60169-4). To connect it to N-type or 7/16 equipment, you will need high-quality 4.3-10 adapters or jumpers.
