The 4-hole flange mounting provides four mechanical contact points for superior grounding performance. This design prevents axial and radial misalignment during high-stress operation. Your installations remain stable in demanding environments.

Precision machining of the center conductor ensures proper mating with male pins. The beryllium bronze material delivers excellent spring characteristics across hundreds of connection cycles. Gold plating minimizes contact resistance and prevents oxidation.

PEI dielectric material offers optimal performance across wide temperature ranges. The material maintains its electrical properties from -65℃ to +125℃ without degradation. Your systems operate reliably in extreme thermal conditions.

Stainless steel construction with passivation treatment provides outstanding corrosion resistance. This combination protects your investment in harsh environmental conditions. The straight orientation simplifies integration into your existing designs.

Frequently Asked Questions

Q: Does this connector work with my existing SMA equipment?

A: Yes, the product is mechanically compatible with SMA and 3.5 mm connectors. However, mating with lower-grade SMA connectors may cause accelerated wear. For optimal performance and longevity, use precision-grade mating connectors.

Q: Why should I choose the 4-hole flange over a 2-hole version?

A: The 4-hole design delivers superior mechanical stability and shielding effectiveness. This becomes critical in high-vibration environments where rotational torque could compromise a 2-hole mount. Your aerospace and military applications particularly benefit from this enhanced security.

Q: What temperature extremes can this connector handle?

A: The operating temperature range spans -65℃ to +125℃. This range covers most industrial, aerospace, and defense applications. The PEI dielectric maintains phase stability across this entire temperature spectrum.

Q: How many connection cycles can I expect?

A: The connector provides ≥500 mating cycles while maintaining electrical performance specifications. Proper torque application and handling extend this service life. Using appropriate mating connectors prevents premature wear.

Q: What makes this connector suitable for phase-stable applications?

A: The PEI dielectric and precision mechanical design minimize phase shift over temperature variations. This characteristic proves essential for beam-forming networks and phased-array radar systems where phase consistency determines system performance.
