The **JN2DS04FKK-R** is a high-performance, waterproof circular connector manufactured by **JAE (Japan Aviation Electronics)**. It belongs to the JN2 series, which is designed for industrial equipment, specifically for small motors and sensors. ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Connector Type** | Receptacle (Female) | | **Number of Contacts** | 4 Positions | | **Current Rating** | Up to 5A per contact | | **Voltage Rating** | 200 VAC | | **Termination Style** | Solder | | **Locking Mechanism** | One-touch Baffle (Snap-in) | | **Ingress Protection** | IP67 (Waterproof when mated) | --- ### 2. Physical & Material Composition * **Shell Material:** High-strength synthetic resin (Zinc-plated/Black). This makes the connector lightweight compared to full-metal industrial connectors while maintaining durability. * **Contact Plating:** Gold plating is typically used to ensure low contact resistance and prevent corrosion over time. * **Mounting Type:** This specific part is a **Panel Mount** receptacle, often used on the housing of a motor or an enclosure. --- ### 3. Core Electronic Features #### A. One-Touch Locking System Unlike traditional threaded connectors that require multiple turns to secure, the JN2DS04FKK-R uses a **one-touch snap-in mechanism**. This provides a tactile "click" to confirm a secure connection, making it ideal for tight spaces where manual threading is difficult. #### B. Environmental Sealing The "IP67" rating indicates that the electronic interface is protected against dust and can withstand immersion in water up to 1 meter for 30 minutes. This is critical for industrial automation where coolant, oil, or water spray may be present. #### C. EMI Shielding Capability The internal structure is designed to minimize electromagnetic interference, which is vital when the connector is used for feedback sensors or precision motor control. --- ### 4. Common Applications * **Industrial Robotics:** Connection points for arm sensors. * **Servo Motors:** Small-sized AC/DC servo motor power and signal lines. * **Machine Tools:** Interface for CNC machinery and automated assembly lines. * **Outdoor Electronics:** Sensors used in weather-exposed environments.
