## Overview of JN2FS04FK2-R The **JN2FS04FK2-R** is a high-performance, small-sized 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. --- ### Key Specifications | Feature | Specification | | :--- | :--- | | **Series** | JN2 Series | | **Number of Contacts** | 4 Positions | | **Contact Gender** | Socket (Female) | | **Mounting Type** | Straight Plug (Cable Mount) | | **Termination Method** | Crimp (Note: Contacts usually sold separately) | | **Rated Current** | 13A per contact (Max) | | **Rated Voltage** | 200 VAC | | **Waterproof Rating** | IP67 (when mated) | --- ### Physical & Material Composition 1. **Shell Material:** Synthetic Resin (High-strength plastic). This makes the connector lightweight compared to full-metal circular connectors. 2. **Locking Mechanism:** One-touch push-twist locking mechanism. It provides a secure connection that is resistant to vibration but allows for quick disconnection. 3. **Color/Finish:** Typically black body with silver/zinc-plated hardware components. 4. **Strain Relief:** The "FK" designation often indicates a specific bushing or gland size for cable diameter compatibility. --- ### Application Usage The JN2FS04FK2-R is commonly found in environments where space is limited but high reliability is required: * **Industrial Robots:** Used for power and signal transmission in articulated arms. * **Servo Motors:** Often used as the primary power or encoder interface. * **Machine Tools:** Ideal for equipment exposed to oil mist or water spray due to its **IP67 rating**. * **Medical Equipment:** Suitable for devices requiring robust, easy-to-clean connections. --- ### Compatibility Note This part number refers to the **Plug Housing**. To complete the assembly, you typically need to purchase the corresponding **crimp contacts** (Sockets) separately, depending on your wire gauge (AWG). Commonly paired contacts include: * `JN1-22-22S-PKG100` (Example contact type) ---
