EZ-400-TM-RP Reverse Polarity TNC (RP-TNC) Male (Plug) Crimp Connector for LMR-400 coaxial cable
EZ-400-TM-RP is a high-performance, Reverse Polarity TNC (RP-TNC) Male (Plug) Crimp Connector engineered by Amphenol Times Microwave Systems. Designed for quick, reliable, and solderless termination of LMR-400 series coaxial cables, this connector is the ideal choice for demanding RF and wireless applications like Wi-Fi, WLAN, antenna systems, and Land Mobile Radio (LMR).
Key Features & Benefits
| Feature | Benefit |
| Solderless EZ-Style Design | Utilizes spring-finger inner contacts for secure, low-resistance connection—eliminating soldering for fast, error-free field installation. |
| Reverse Polarity TNC Interface | Features a female center contact in a male body, ensuring compatibility with RP-TNC female components in specialized wireless systems. |
| Quick Crimp Outer Attachment | Securely assembled in under 30 seconds with a standard .429″ hex crimp tool, minimizing installation time and errors. |
| High-Performance RF | Offers reliable signal integrity with low VSWR (Voltage Standing Wave Ratio) up to 2.5 GHz (some sources indicate up to 6 GHz). |
| Durable Construction | Gold-plated center contact and Alballoy or Nickel-plated body provide excellent corrosion resistance and robust performance in harsh environments. |
| Compatibility | Optimized for LMR-400, TCOM-400, and T-RAD-400-FR type cables. |
