N-Female flange connector for RG402 cable (soldering, no thread)

N-Female Flange Connector for RG402 Cable (Solder Type, No Thread)

The N-Female flange connector for RG402 cable is designed to deliver high-performance, stable, and reliable RF connections in telecommunications, measurement, and antenna systems. This model supports direct soldering without threading, ensuring minimal signal loss and maximum mechanical stability across a wide frequency range.

The connector features a 25×25 mm flange base with four mounting holes, allowing secure attachment to enclosures, RF panels, or chassis. This mechanical design enhances vibration resistance and long-term durability in demanding environments. It is fully compatible with RG402 semi-rigid coaxial cable (0.141"), which is widely used in high-frequency systems.

A PTFE dielectric (Teflon) is used for its excellent thermal stability and low dielectric constant, reducing signal degradation. The gold-plated center pin is soldered directly to the inner conductor, providing a precise, gas-tight, and corrosion-resistant RF connection. The connector body is made of nickel-plated brass, which offers high durability and resistance to environmental factors.
