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

Amphenol 132231 SMA Straight Crimp Plug

The Amphenol 132231 is a high-frequency, precision-machined 50-Ω straight male (plug) SMA RF connector designed for crimp termination onto low-loss 50 Ω coaxial cables, specifically RG-8X, LMR-240, Belden 9258, and 240-series low-loss cable assemblies. Engineered for high-reliability marine radio, GPS/GNSS, cellular booster, satellite communication, and radar interconnects, it provides low VSWR and consistent RF power transmission up to 6 GHz.

Constructed with a gold-plated brass body and a captive/crimp gold-plated brass center pin, this connector uses a threaded coupling mechanism to maintain stable electrical performance under severe physical vibration and movement. The included crimp ferrule ensures high tensile cable-retention strength and proper grounding around the outer braided shield.

Key Features

• Optimized for 240-Series Coax: Engineered to fit the thicker dielectric and outer jackets of RG-8X and LMR-240 low-loss coaxial cables without binding.

• Gold-Plated Brass Contacts: Gold plating on center pin and outer connector housing ensures minimal contact resistance and prevents oxidation in salt-air environments.

• Threaded Coupling Mechanism: Compact threaded coupling ring provides positive, vibration-proof mating with standard SMA female jacks.

• High-Frequency Rating: Operates smoothly from DC up to 6 GHz with low insertion loss, making it suitable for VHF, AIS, 4G/5G LTE, Wi-Fi, and satellite frequencies.
