## Overview of JN2FS04FK1X-R The **JN2FS04FK1X-R** is a high-performance, small-size circular connector developed by **JAE (Japan Aviation Electronics)**. It belongs to the **JN2 Series**, which is specifically designed for industrial equipment, robotics, and waterproof applications. --- ### Technical Specifications | Feature | Specification | | :--- | :--- | | **Series** | JN2 (Small Circular Connector) | | **Connector Type** | Straight Plug | | **Number of Contacts** | 4 Positions | | **Contact Gender** | Socket (Female) | | **Termination Method** | Crimp (Requires separate contacts) | | **Rated Current** | 13A per contact (Max) | | **Rated Voltage** | 200 VAC | | **Waterproof Rating** | IP67 (when mated) | --- ### Key Electronic & Design Components #### 1. Shell and Housing The "FS" in the part number indicates a **straight plug** configuration. The outer shell is typically made of a high-strength synthetic resin, providing excellent insulation and weight reduction compared to traditional metal connectors. #### 2. Contact Arrangement (4-Pin) This specific model features **4 positions**. * **Power/Signal:** Often used for power supply to motors (U, V, W, Ground) or for high-current signal transmissions. * **Grounding:** The JN2 series is designed with a ground connection that engages before the power pins (First-to-mate/Last-to-break) for safety. #### 3. Locking Mechanism It features a **One-touch vibration-resistant locking mechanism**. Instead of threading (screwing), it uses a push-and-twist or snap-in system that ensures a secure connection even in high-vibration industrial environments. #### 4. Waterproofing (IP67) The connector includes internal O-rings and cable gaskets. When properly mated with its counterpart (receptacle), it prevents the ingress of dust and allows for temporary immersion in water. --- ### Common Applications * **Industrial Robots:** Servomotors and controllers. * **Machine Tools:** Sensors and power distribution. * **Automation Equipment:** Communication links in harsh environments. * **Medical Equipment:** Devices requiring robust, washable connections. --- ### Necessary Accessories To complete the assembly of the JN2FS04FK1X-R, you generally require: 1. **Crimp Contacts:** (e.g., JN1-22-22S-PKG100) - The plug body does not usually come with the metal pins. 2. **Cable Glands:** To maintain the IP67 seal around the wire entry point.
