The **CONSMA005-R178** is a high-quality, precision RF (Radio Frequency) connector manufactured by **Linx Technologies** (now part of TE Connectivity). It is specifically designed for mounting on thin-walled enclosures or bulkheads. --- ### 1. Key Technical Specifications The following table outlines the core electrical and physical characteristics of the component: | Feature | Specification | | :--- | :--- | | **Connector Type** | SMA Female (Jack) | | **Mounting Style** | Bulkhead Mount (Rear Mount) | | **Termination** | Solder Pot / Solder Cup | | **Impedance** | 50 $\Omega$ (Ohms) | | **Frequency Range** | 0 to 18 GHz | | **Body Material** | Gold-plated Brass | | **Dielectric** | PTFE (Teflon) | | **Fastening Type** | Threaded (1/4"-36 UNS-2A) | --- ### 2. Functional Design Parts The CONSMA005-R178 consists of several critical sub-components that ensure signal integrity: 1. **Outer Body:** Made of gold-plated brass to provide excellent corrosion resistance and a low-resistance electrical path to ground. 2. **Center Contact:** A gold-plated female socket designed to receive a standard SMA male pin. It features a "solder cup" on the rear for manual wire attachment. 3. **Insulator:** High-grade PTFE provides stable insulation and maintains the 50-ohm characteristic impedance across high frequencies. 4. **Hardware Kit:** Usually includes a **hex nut** and a **lock washer** to secure the connector to a panel or chassis. --- ### 3. Common Applications Due to its robust build and frequency range, this part is used in: * **Wireless Infrastructure:** WiFi routers, base stations, and cellular gateways. * **Enclosure Transitions:** Passing an RF signal from internal circuitry (via a wire) to an external antenna. * **Test Equipment:** Providing a durable interface for signal generators or oscilloscopes. * **IoT Devices:** Connecting external high-gain antennas to small-form-factor sensor nodes. --- ### 4. Installation Considerations * **Panel Thickness:** The "R178" designation often refers to the specific dimensions or the compatible cable/panel thickness; ensure your enclosure wall is thin enough for the threads to clear for the nut. * **Soldering:** Use a fine-tip soldering iron. Excessive heat can melt the PTFE dielectric, causing the center pin to shift and ruining the 50-ohm impedance. * **Torque:** Do not over-tighten the mounting nut, as this can deform the chassis or strip the fine 1/4"-36 threads.
