The term **2PN-R** typically refers to a specific variation of electronic connectors or components, most commonly associated with **Circular Aviation Connectors** (such as the GX series) or specialized **Relay/Switch configurations**. Below is a breakdown of the parts and technical specifications often associated with this designation. --- ### 1. General Identification The "2PN-R" code is generally broken down as follows: * **2**: Often indicates the number of pins/cores (2-pole). * **P**: Stands for "Plug" (the male connector part). * **N**: Can signify a "Normal" or "Non-waterproof" standard, or a specific shell size in some catalogs. * **R**: Usually denotes a "Reverse" gender, "Right-angle" orientation, or "Receptacle" (socket) depending on the manufacturer (e.g., Nanaboshi or Hirose). --- ### 2. Common Component: Circular Connectors In the context of power and signal transmission, 2PN-R parts often look like metal-threaded cylinders. | Feature | Specification (Typical) | | :--- | :--- | | **Pin Count** | 2 Pins | | **Material** | Zinc alloy / Chrome plating | | **Insulator** | Bakelite or PPS (Polyphenylene sulfide) | | **Contact Material** | Copper (Silver or Gold plated) | | **Connection Type** | Solder or Screw terminal | | **Current Rating** | 5A to 15A (depending on size) | --- ### 3. Application Use-Cases These electronic parts are primarily used in environments requiring secure, vibration-resistant connections: 1. **Industrial Machinery:** Providing power to small motors or sensors. 2. **Audio Equipment:** Used in older or specialized stage lighting and sound rigs. 3. **Aviation/Marine:** Connecting navigational tools where a screw-lock mechanism prevents accidental disconnection. 4. **DIY Electronics:** Frequently used for GX12 or GX16 "Aviation Plugs" for custom keyboards or CNC machines. --- ### 4. Technical Diagram Overview When looking at a 2PN-R part, you will typically find these sub-components: * **Outer Shell:** A metal casing that protects the internal wiring. * **Locking Ring:** A threaded nut that screws onto the mating socket to ensure it stays plugged in. * **Clamp:** A strain relief mechanism at the back to prevent the cable from being pulled out of the solder joints. * **Contact Pins:** Two metal prongs that carry the electrical load. ---
