- Gold-plated copper contacts resist corrosion
- PTFE insulation ensures stable dielectric performance
- O-ring seal provides waterproof panel mounting
SMA 50 Ohm RF Connector
This SMA female jack is a straight coaxial adapter designed for panel mounting with an O-ring seal. It suits RF engineers, hobbyists and installers who need a gold-plated 50 Ohm interface for test equipment, antennas or custom cable assemblies. The PTFE insulator and copper body provide stable impedance in controlled environments.
Gold Plating and O-Ring Seal
Gold-plated contacts reduce contact resistance and resist oxidation over repeated mating cycles. The integrated O-ring adds a waterproof barrier at the panel cut-out, preventing moisture ingress in outdoor or humid installations. PTFE insulation maintains consistent dielectric performance across the operating temperature range.
10x22 mm Panel Mount Footprint
The 10 by 22 millimetre body fits standard panel cut-outs for SMA bulkhead mounting. It comfortably handles typical low-power RF signals up to the connector's 50 Ohm rating. The straight body style offers no right-angle clearance, so tight chassis depths may require an alternative form factor.

Questions about this item
Will the gold-plated SMA connector need periodic re-plating or contact cleaning?
The gold-plated copper contacts on this 50 Ohm SMA jack resist oxidation, so routine re-plating is not required; occasional inspection for debris is sufficient.
What is the first limit reached when this connector carries continuous RF power?
The 50 Ohm impedance rating and PTFE insulator set the practical power ceiling; sustained loads beyond the connector's RF power rating will cause heating at the dielectric first.
Does the panel-mount SMA jack generate noticeable heat or noise during all-day operation?
As a passive coaxial component, the straight SMA female jack produces no audible noise and negligible heat; the gold-plated copper body stays at ambient temperature under normal RF throughput.
