The **JAPD2-5-R/Q** is a part number typically associated with professional-grade electrical connectors, specifically within the **Circular Connector** or **Industrial Plug/Socket** categories. These components are designed for high-reliability power or signal transmission in demanding environments. --- ### 1. General Specifications While specific technical data can vary slightly by manufacturer (often associated with brands like **JAE** or specialized industrial suppliers), the alphanumeric code generally breaks down as follows: | Feature | Description | | :--- | :--- | | **Series** | JAPD (Commonly indicates a rugged, high-density circular series) | | **Shell Size** | 2 (Reference to the physical diameter of the housing) | | **Contact Count** | 5 (Specifies a 5-pin configuration) | | **Contact Gender** | R (Often denotes a Receptacle/Socket) | | **Keying/Finish** | Q (Specific polarization or plating designation) | --- ### 2. Key Electronic Characteristics These parts are engineered to maintain electrical integrity under mechanical stress. * **Current Rating:** Typically ranges from **5A to 13A** per contact, depending on the wire gauge used. * **Voltage Rating:** Generally rated for **250V to 500V AC/DC**, making them suitable for motor controls and power supplies. * **Insulation Resistance:** Usually minimum **1000MΩ**, ensuring no leakage between pins. * **Dielectric Withstanding Voltage:** Capable of handling surges (often up to **1500V AC**) for one minute without breakdown. --- ### 3. Physical & Material Composition The "electronic" performance is heavily reliant on the materials used in the pins and housing: * **Contacts:** Usually made of **Copper Alloy** with **Gold or Silver plating** to minimize contact resistance and prevent oxidation. * **Insulator:** High-grade synthetic resin (like PBT) to withstand high temperatures during soldering or operation. * **Coupling Mechanism:** Screw-lock or bayonet style to ensure the connection does not break due to vibration. --- ### 4. Typical Applications These connectors are found in sectors where a standard consumer-grade USB or RJ45 connector would fail: 1. **Industrial Automation:** Sensor arrays and actuator connections. 2. **Robotics:** Power and signal lines for articulated arms. 3. **Medical Equipment:** Reliable power interfaces for diagnostic machinery. 4. **Transportation:** Control systems in rail or heavy machinery. ---
