### JN2FS04FKK-R: Product Overview The **JN2FS04FKK-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 for industrial equipment applications, particularly where space-saving and waterproof integrity are required. --- ### Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Series** | JN2 (Small Waterproof Circular) | | **Connector Type** | Socket (Female) | | **Number of Contacts** | 4 Positions | | **Shell Size** | S (Small) | | **Termination Method** | Crimp (Contacts sold separately) | | **Mounting Style** | Cable Mounted (Plug) | | **Waterproof Rating** | IP67 (when mated) | | **Rated Current** | 5A per contact | | **Rated Voltage** | 200 VAC | | **Dielectric Withstanding Voltage** | 900 VAC (for 1 minute) | --- ### Design and Construction #### 1. Material Composition * **Insulator:** Synthetic resin (High durability and insulation). * **Shell:** Zinc alloy or Synthetic resin (depending on specific sub-variant), usually finished with a black chrome or nickel plating for corrosion resistance. * **Grommet/Seal:** Synthetic rubber (Provides the IP67 moisture protection). #### 2. Locking Mechanism The JN2 series features a **One-touch push-twist locking mechanism**. * **Ease of Use:** It allows for secure mating and unmating even in tight spaces where traditional screw-thread connectors are difficult to handle. * **Vibration Resistance:** The locking system is designed to stay secure under the mechanical stress common in industrial robotics. --- ### Pin Configuration & Wiring The "04" in the part number signifies **4 contacts**. In industrial power applications, this is frequently used for: 1. **3-Phase Power:** (L1, L2, L3 + Ground). 2. **Motor Control:** Power (2 pins) + Signal/Brake (2 pins). > **Note:** The "FKK" designation indicates that this is the **socket housing**. The actual metal crimp terminals (contacts) must be purchased separately based on the wire gauge (AWG) you are using. --- ### Applications * **Industrial Robotics:** Connection points for sensors and small motors. * **Machine Tools:** Control panels and peripheral devices. * **Automation Equipment:** Factory floor sensors requiring wash-down protection. * **Medical Devices:** Where reliable, waterproof circular connections are necessary. --- ### Recommended Mating Part To complete a connection, the **JN2FS04FKK-R** (Cable Plug) typically mates with a **JN2AS04MKK** (Receptacle) or similar 4-pin male counterparts from the JN2 series.
