The **CC-RSPNMCN24** is a specialized coaxial cable assembly manufactured by **Red Lion Controls**. It is primarily used in industrial wireless networking to connect a radio device to an antenna. ### Technical Specifications | Feature | Specification | | :--- | :--- | | **Cable Type** | LMR-195 (or equivalent low-loss coaxial) | | **Connector A** | RP-SMA Plug (Reverse Polarity SMA Male) | | **Connector B** | N-Type Male | | **Length** | 24 Feet (approx. 7.3 meters) | | **Impedance** | 50 Ohms | | **Application** | Cellular, Wi-Fi, and Radio frequency (RF) transmission | --- ### Component Breakdown #### 1. RP-SMA Plug (Connector A) * **Design:** "Reverse Polarity" means the center pin configuration is swapped compared to a standard SMA. In an RP-SMA Male (Plug), there is a **socket** (hole) instead of a pin, but the threads are on the inside. * **Purpose:** This is the standard connector found on most industrial Wi-Fi routers, cellular gateways, and Red Lion Sixnet/N-Tron series radios. #### 2. N-Type Male (Connector B) * **Design:** A large, rugged, threaded RF connector. It features a center pin and a heavy-duty outer shell. * **Purpose:** Usually used to connect to outdoor high-gain antennas or lightning surge arrestors. It is designed to be weather-resistant and durable for industrial environments. #### 3. LMR-195 Coaxial Cable * **Loss Profile:** LMR-195 is a "Low Loss" cable. At a length of 24 feet, it is important to account for signal attenuation (signal strength loss). * **Flexibility:** It has a relatively small diameter (~4.95mm), making it easier to route through conduit compared to thicker cables like LMR-400, though it has slightly higher signal loss per foot. --- ### Typical Usage Scenario This cable acts as the bridge between a **DIN-rail mounted radio** inside a control panel and an **external antenna** mounted on a mast or the roof of a building. 1. **Radio End:** The RP-SMA end screws onto the "Antenna" port of the wireless device. 2. **Antenna End:** The N-Type end screws into the base of the antenna (or a lightning protector). --- ### Performance Considerations * **Signal Loss:** At 2.4 GHz (Standard Wi-Fi), a 24-foot LMR-195 cable will lose approximately **4.5 dB to 5 dB** of signal strength. * **Environmental:** Ensure the N-Type connection is properly weather-sealed (using silicone tape or heat shrink) if exposed to the elements, as moisture in the cable will degrade performance rapidly.
