The **12RDK-R** is a specific part number typically associated with **JST (Japan Solderless Terminals)**. It belongs to the **RK series**, which are insulation displacement connectors (IDC) designed for daisy-chaining or end-to-end connections in internal wiring. --- ### ## Technical Specifications Below is a breakdown of the typical characteristics for the 12RDK-R connector: | Feature | Specification | | :--- | :--- | | **Circuit Count** | 12 Pins / Positions | | **Connector Type** | Receptacle (Female) | | **Pitch** | 2.0 mm | | **Termination Style** | IDC (Insulation Displacement) | | **Wire Gauge (AWG)** | Typically 28 AWG to 26 AWG | | **Color** | Red (often indicates specific keying or wire gauge) | | **Current Rating** | 1.0A AC/DC | | **Voltage Rating** | 100V AC/DC | --- ### ## Component Breakdown The part number "12RDK-R" can be deciphered as follows: * **12**: Represents the number of circuits (12 pins). * **RK**: Represents the JST RK connector series. * **D**: Generally indicates a specific configuration or "Daisy-chain" capability. * **R**: Often refers to the color (Red) or a specific material variant. --- ### ## Key Features 1. **IDC Technology**: Unlike crimp terminals, IDC allows the wire to be pushed into a slot that cuts the insulation and makes contact with the conductor. This is faster for mass production. 2. **Daisy-Chain Design**: The RK series is specifically designed so that wires can pass through the connector, allowing multiple connectors to be attached to a single ribbon cable or wire harness. 3. **Twin U-Slot**: Provides high reliability by making contact with the wire at two points. --- ### ## Typical Applications * **Consumer Electronics**: Internal signal routing in printers, scanners, and televisions. * **Industrial Controls**: Connecting LED displays or sensor arrays where multiple points need to be linked in a series. * **Office Automation**: Wiring harnesses where space is at a premium and 2.0mm pitch is required. ---
