The **JN2FS04FKKX-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, ease of use, and resistance to harsh environments. --- ### 1. Key Technical Specifications The following table outlines the core electronic and physical attributes of the JN2FS04FKKX-R: | Parameter | Specification | | :--- | :--- | | **Connector Type** | Straight Plug | | **Number of Contacts** | 4 | | **Contact Gender** | Socket (Female) | | **Termination Method** | Crimp (Note: Contacts are usually sold separately) | | **Current Rating** | Up to 13A per contact | | **Voltage Rating** | 200 VAC | | **Ingress Protection** | IP67 (Dust-tight and waterproof) | | **Shell Size** | Small / Lightweight Plastic Body | | **Locking Mechanism** | One-touch Vibration-resistant | --- ### 2. Physical Composition and Materials The JN2FS04FKKX-R is engineered for both strength and electrical insulation. * **Shell Body:** High-strength synthetic resin (plastic), which makes it significantly lighter than traditional metal circular connectors. * **Insulator:** Synthetic resin with high dielectric properties to prevent arcing between the 4 pins. * **Gasket/Seal:** Synthetic rubber (NBR or Fluorine) ensuring the IP67 rating when mated. * **EMI Shielding:** This specific model is typically non-shielded (plastic shell), though it provides excellent insulation for power and signal lines. --- ### 3. Core Features #### One-Touch Locking System Unlike threaded connectors that require multiple turns, the JN2 series uses a **push-twist locking mechanism**. This ensures a secure connection even in high-vibration environments, common in robotics and factory automation. #### Environmental Resistance When mated, the connector is rated **IP67**. This means it is protected against dust ingress and can withstand immersion in water up to 1 meter deep for 30 minutes. #### Versatile Application The 4-pin configuration is frequently used for: * **Small Motors:** Power supply for AC/DC servo motors. * **Sensors:** Industrial sensor arrays. * **Robotic Arms:** Signal and power transmission in tight spaces. --- ### 4. Required Accessories To complete the assembly, you typically need: 1. **Crimp Contacts:** (e.g., JN1-22-22S or JN1-22-20S depending on wire gauge). 2. **Cable Clamp:** To provide strain relief for the incoming wire bundle. ---
