Amphenol 132231RP RP-SMA Crimp Connector RG-8X LMR-240

Amphenol 132231RP RP-SMA Straight Crimp Plug

The Amphenol 132231RP is a precision 50-Ω Reverse Polarity SMA (RP-SMA) straight male (plug) RF connector engineered for crimp termination onto low-loss 50 Ω coaxial cables, including RG-8X, LMR-240, Belden 9258, and 240-series cable assemblies. Reverse Polarity (RP) connectors swap the internal contact genders: while maintaining standard SMA male threading, this plug houses a female socket contact inside rather than the standard male pin.

RP-SMA connectors are widely specified in Wi-Fi access points, marine 4G/5G cellular routers, satellite data terminals, and IoT marine gateways to prevent improper connection of standard high-power VHF/UHF transmitters. Built with gold-plated brass contacts, PTFE insulation, and a threaded coupling mechanism, it delivers stable electrical performance up to 6 GHz.

Key Features

• Reverse Polarity Configuration: Features standard SMA male coupling threads with an internal female socket contact for regulatory compliance in wireless communication devices.

• Optimized for 240-Series Coax: Sized specifically to fit the thicker dielectric and outer jacket dimensions of RG-8X and LMR-240 low-loss cables.

• Gold-Plated Contacts: Gold-plated center contact and durable brass housing ensure minimal signal loss and long-term corrosion resistance in marine environments.

• Threaded Coupling Mechanism: Compact threaded 1/4''-36 connection provides vibration-resistant, secure mating with RP-SMA female jacks.
