## JN2FS04FK2X-R: Product Overview The **JN2FS04FK2X-R** is a high-performance, small-form-factor circular connector manufactured by **JAE (Japan Aviation Electronics)**. It belongs to the **JN2 Series**, which is designed specifically for industrial applications requiring waterproof capabilities and a secure locking mechanism. --- ### Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Series** | JN2 (Small Waterproof Circular) | | **Connector Type** | Straight Plug | | **Number of Contacts** | 4 Positions | | **Termination Type** | Solder Termination | | **Current Rating** | 5A to 13A (depending on wire gauge) | | **Voltage Rating** | 200 VAC | | **Waterproof Rating** | IP67 (when mated) | | **Locking Mechanism** | One-touch Vibration-resistant | --- ### Core Electronic & Structural Components #### 1. The Shell (Body) The "FS" in the part number indicates a **Straight Plug**. The outer body is typically constructed from a high-strength synthetic resin. This material provides: * **Electrical Insulation:** Prevents shorting between the contacts and the user. * **Weight Reduction:** Ideal for handheld or mobile industrial equipment. #### 2. The Insert (Insulator) The internal core holds the 4 contacts in a fixed geometric arrangement. It is designed to maintain high dielectric strength to prevent "arcing" between the four pins under high-voltage loads. #### 3. Contact Arrangement (04FK) * **4 Contacts:** This specific model features 4 pins. * **Socket Type:** The "F" indicates female socket contacts (the "K" refers to the specific keying or arrangement). * **Material:** Contacts are usually gold-plated copper alloy to ensure low contact resistance and prevent corrosion over time. #### 4. The One-Touch Locking Mechanism Unlike traditional threaded connectors that require multiple turns, the JN2 series uses a **snap-in/push-pull** mechanism. * **Electronic Integrity:** This ensures that vibrations in industrial environments do not lead to intermittent signals or "micro-breaks" in the circuit. --- ### Applications Due to its IP67 rating and rugged build, the JN2FS04FK2X-R is commonly found in: * **Industrial Robots:** Connecting sensors and small motors. * **Machine Tools:** Power and signal transmission in dusty or oily environments. * **Medical Equipment:** Where easy cleaning and secure connections are vital. * **Communication Devices:** Outdoor wireless base stations or portable radios. --- ### Part Number Breakdown * **JN2:** Series Name. * **F:** Plug (Cable side). * **S:** Straight shape. * **04:** Number of positions (4). * **F:** Female Socket. * **K:** Contact size/type. * **2:** Shell size. * **X:** Variation/Polarization code. * **R:** RohS Compliant/Revised version.
