The **2JS2-R** refers to a specific series of **Wire-to-Board connectors**, typically manufactured by companies like **JST** or compatible generic electronic component manufacturers. These are widely used in consumer electronics, power supplies, and internal computer cabling. --- ### ## Technical Specifications The "2JS" series is characterized by its pitch and locking mechanism. Below is a breakdown of the typical electronic specifications for the 2JS2-R part: | Characteristic | Specification | | :--- | :--- | | **Pitch** | 2.0 mm (Distance between pin centers) | | **Current Rating** | 1.0A to 2.0A AC/DC | | **Voltage Rating** | 100V to 250V AC/DC | | **Contact Resistance** | 20mΩ Max (Initial) | | **Insulation Resistance** | 1000MΩ Min | | **Temperature Range** | -25°C to +85°C | | **Mounting Type** | Through-hole or SMT (Surface Mount) | --- ### ## Component Anatomy The 2JS2-R is not a single piece but a part of a connection system. It usually refers to the **Header (Male)** component. 1. **Housing (Insulator):** Usually made of Nylon 66 (UL94V-0). It provides the structure and keeps the pins separated to prevent short circuits. 2. **Contacts (Pins):** Made of Brass or Phosphor Bronze, often plated with **Tin** or **Gold** to enhance conductivity and prevent oxidation. 3. **Friction Lock:** The "R" in some naming conventions refers to a specific orientation or a locking mechanism that ensures the female housing stays securely attached under vibration. --- ### ## Application & Usage These connectors are found in compact electronic assemblies where space is limited but a secure connection is required. * **LED Lighting:** Connecting LED strips to control boards. * **Computer Peripherals:** Internal fan headers or front-panel connectors. * **Industrial Controls:** Signal transmission between PCB layers. * **Household Appliances:** Control panels for microwave ovens or washing machines. --- ### ## Wiring Reference If you are crimping wires for this connector, ensure you are using the correct wire gauge (AWG). ```text Wire Compatibility: - Range: 24 AWG to 30 AWG - Strip Length: 1.5mm to 2.0mm - Tooling: Requires a 2.0mm pitch crimping tool ```
