The **FCR-A1F-R** is a specific model of an electronic component, typically categorized as a **D-Subminiature (D-Sub) Connector** or a specialized interface connector often used in industrial automation, robotics, and telecommunications. Below is a detailed breakdown of its electronic parts and technical specifications. --- ## 1. Technical Specifications Table | Feature | Specification | | :--- | :--- | | **Component Type** | D-Subminiature Connector | | **Series** | FCR Series | | **Mounting Style** | Right Angle / PCB Mount | | **Gender** | Female (Receptacle) | | **Contact Material** | Copper Alloy | | **Plating** | Gold over Nickel (contact area) | | **Termination Style** | Through-hole (Solder) | | **Voltage Rating** | 250V AC/DC | --- ## 2. Key Electronic Parts and Construction ### A. The Housing (Insulator) The body is usually made of a high-temperature thermoplastic (such as PBT or LCP). - **Function:** It insulates the pins from each other and the outer shell. - **Flammability:** Usually UL 94V-0 rated to prevent fire hazards in electronic circuits. ### B. Contacts (The Conductive Path) The internal pins are the most critical electronic parts. - **Material:** High-conductivity Copper Alloy. - **Gold Plating:** The "R" in the suffix often denotes specific plating or RoHS compliance. Gold plating ensures low contact resistance and prevents oxidation over long-term use. ### C. Metal Shell (Shielding) The outer metal frame (often tin-plated steel) acts as an **EMI/RFI Shield**. - **Grounding:** It provides a path to ground to protect the signal from electromagnetic interference. - **Mechanical Strength:** Provides the structural integrity needed for repeated plugging/unplugging. ### D. Board Locks / Mounting Hardware The FCR-A1F-R typically features metal "harpoons" or board locks. - **Purpose:** These are soldered into the PCB to provide mechanical stability, ensuring the connector doesn't snap off the board when a cable is attached. --- ## 3. Typical Application Use-Cases 1. **Industrial Controllers:** Used on PLCs (Programmable Logic Controllers) for data communication. 2. **Serial Interfaces:** Common for RS-232, RS-422, or RS-485 communication protocols. 3. **Peripheral Connection:** Connecting sensors or human-machine interfaces (HMI) to a main processing board. --- ## 4. Part Number Breakdown (Generic FCR Logic) * **FCR:** Series identifier (Right Angle Interface). * **A:** Specific shell size or mounting configuration. * **1:** Number of rows or contact density. * **F:** Female gender (Receptacle). * **R:** Denotes Right Angle orientation and/or RoHS compliance.
