The **27DS-R-PC-CF** is a specific electronic hardware component, typically categorized as a high-performance **D-Subminiature (D-Sub) Connector**. These connectors are widely used in computing, telecommunications, and industrial control systems for signal and power transmission. Below is a detailed breakdown of its parts and specifications. --- ### 1. Technical Specifications | Feature | Description | | :--- | :--- | | **Connector Type** | D-Subminiature | | **Series** | 27DS (Commonly associated with specific high-density or standard density series) | | **Orientation** | Right Angle (indicated by "R") | | **Mounting Type** | Through-hole PC Tail (indicated by "PC") | | **Shell Size** | Standardized size (usually 9, 15, 25, or 37 pins depending on manufacturer prefix) | | **Contact Plating** | Gold Flash or Selective Gold (indicated by "CF" or specific suffixes) | --- ### 2. Breakdown of the Part Number The alphanumeric code usually follows a modular logic used by manufacturers (such as Adam Tech, NorComp, or similar electronic hardware brands): * **27DS**: The base series. "27" often refers to the specific contact spacing or shell design, while "DS" stands for **D-Sub**. * **R**: Stands for **Right Angle**. This means the pins exit the connector body at a 90-degree angle, allowing the connector to be mounted flat against a Printed Circuit Board (PCB). * **PC**: Stands for **PC Tail**. These are the sharp, thin metal leads that are inserted into holes on a PCB for soldering. * **CF**: This typically refers to the **Contact Finish** or specific **Color/Flange** options. In many catalogs, "CF" indicates a specific plating (like Gold Flash) or a "Closed Frame" / "Compact Form" design. --- ### 3. Key Physical Components 1. **Metal Shell (Shielding):** Provides structural integrity and EMI/RFI shielding. It is usually made of steel with tin or zinc plating. 2. **Insulator (Dielectric):** The plastic block (often PBT or Nylon) that holds the pins in place and prevents electrical shorting between them. 3. **Contacts (Pins/Sockets):** Made of copper alloy. The "PC" designation implies these are designed for wave soldering onto a board. 4. **Boardlocks / Mounting Brackets:** Since it is a "Right Angle" connector, it usually features metal brackets or "harpoons" to secure the connector to the PCB before soldering. --- ### 4. Common Applications * **Industrial Automation:** Connecting PLCs to sensors. * **Computing:** Legacy VGA or Serial (RS-232) ports. * **Telecommunications:** Data transmission interfaces. * **Medical Equipment:** Secure, screw-locked cable connections. ---
