Durable SMA Female To Female 4-Hole Flange Mount Brass Body Adapter For Telecommunication

Application

• Connecting antennas to RF equipment

• Linking test equipment (like spectrum analyzers or signal generators) to DUTs (devices under test)

• Integrating components in RF communication systems (e.g., Wi-Fi, LTE, GPS, IoT modules)

• patient monitoring systems with wireless connectivity

• RF ablation, telemetry, and diagnostic tools

• MRI, CT, and ultrasound imaging devices

Connector Type:

SMA

Specification

FAQ

Sample Delivery Time

Regular models require 15 days, while some complex connectors require 25 days.

Sample Fee

Most RF connectors are CNC-machined parts and do not require mold-making.

However, each part needs to be fine-tuned on the CNC machine. Typically, a single sample costs $200.

This fee will be refunded after a 5K bulk order.

Guarantee

Brass RF connectors come with a one-year warranty.

Stainless steel connectors come with a three-year warranty.

The lifespan also depends on the contact material beryllium contacts offer better durability.

ROHS & REACH Compliance

Our products fully comply with ROHS & REACH regulations.

Does LENORF Offer Military-Grade Products?

Materials

Common materials include:

Body: Brass, stainless steel

Insulator: PTFE, PEEK

Contacts: Brass, phosphor bronze, beryllium copper

Other: Aluminum, titanium alloy

What materials are RF connectors made of?

Body: Brass, stainless steel, or beryllium copper (with nickel, gold, or silver plating). Insulator: PTFE, PE, or advanced low-loss dielectrics. Contacts: Gold-plated brass or beryllium copper for low resistance and durability.

Are RF connectors weatherproof?

Some RF connectors are designed with gaskets and sealing (e.g., N-type, 4.3-10) for outdoor telecom, antennas, and harsh environments. Indoor lab connectors (e.g., SMA, BNC) are usually not weatherproof unless specified.

What’s the difference between male and female RF connectors?

Male: Has a center pin and usually an outer thread or bayonet. Female: Has a receptacle (socket) for the center pin and matching thread. Some connectors (like SMA) can be confusing because “reverse polarity” (RP-SMA) swaps pin/socket configuration.

What is VSWR, and why does it matter?

VSWR (Voltage Standing Wave Ratio) indicates signal reflection. Ideal: 1.0 (perfect match). Lower VSWR means less signal loss and distortion.
