### Overview of JN2DS04FK2-R The **JN2DS04FK2-R** is a high-performance, waterproof circular connector manufactured by **JAE (Japan Aviation Electronics)**. It belongs to the **JN2 series**, which is specifically designed for industrial applications requiring durability, space-saving designs, and ease of installation. --- ### Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Connector Type** | Receptacle (Small Type) | | **Number of Contacts** | 4 Pins | | **Rated Current** | Up to 5A (depending on wire size) | | **Rated Voltage** | 200 VAC | | **Waterproof Rating** | IP67 (when mated) | | **Termination Method** | Solder | | **Mounting Type** | Panel Mount (Front-mount) | | **Mating Style** | One-touch Push-Pull Locking | --- ### Component Breakdown #### 1. Mechanical Design * **One-Touch Locking:** Unlike traditional threaded connectors, this uses a push-pull mechanism. This allows for quick mating and unmating even in tight spaces where rotating a nut is difficult. * **Small Footprint:** The "S" in the series indicates a small-shell size, making it ideal for compact industrial machinery and handheld devices. * **Robust Housing:** Usually constructed from high-strength synthetic resin, providing a balance between lightweight design and physical durability. #### 2. Electrical Performance * **4-Contact Configuration:** Typically used for power supply (V+, V-, Ground) or signal transmission. * **Gold Plating:** The contacts are often finished with gold plating to ensure low contact resistance and prevent oxidation over long-term use. #### 3. Environmental Protection * **IP67 Rating:** The "R" in the suffix often denotes high environmental resistance. It is dust-tight and can withstand immersion in water up to 1 meter for 30 minutes. * **Vibration Resistance:** The locking mechanism is designed to prevent accidental decoupling in high-vibration environments, such as on a factory motor. --- ### Common Applications * **Industrial Robots:** Internal wiring for sensors and actuators. * **Servo Motors:** Connection points for power and feedback. * **Medical Equipment:** Devices requiring frequent sterilization or liquid exposure. * **Communication Equipment:** Small outdoor base stations or ruggedized networking gear. --- ### Comparison with Similar Parts | Part Number | Difference | | :--- | :--- | | **JN1 Series** | Standard plastic type, lower vibration resistance. | | **JN2 Series** | Enhanced version with metal reinforcement in the locking part for higher strength. | | **JN2DS10SL2** | Higher pin density (10 contacts) in a similar shell size. |
