The **M6DPP-CNR-R** is a specific part number primarily associated with **3M’s 6-Series Ribbon Cable Connectors**. It belongs to the "M6" family of high-density connectors used in industrial, computing, and telecommunications hardware. --- ### 1. Technical Specifications The part number is an alphanumeric code representing specific physical and electrical characteristics: | Feature | Specification Details | | :--- | :--- | | **Connector Type** | IDC (Insulation Displacement Connector) | | **Series** | M6 Series (Mini Delta Ribbon / MDR style) | | **Pitch** | Typically 0.050" (1.27 mm) or 2.0 mm (varies by sub-series) | | **Mounting Type** | PCB Mount (Right Angle or Vertical) | | **Pin Configuration** | Double Row | | **Plating** | Gold over Nickel (standard for reliability) | | **Termination** | Through-hole or Solder tail | --- ### 2. Breakdown of the Part Number Components While exact manufacturer prefixes can vary slightly, the "M6DPP" nomenclature generally follows this logic: * **M6**: The product family (High-density miniature connectors). * **DPP**: Denotes a **Dual-in-line Plug/Socket** configuration with specific pin counts. * **CNR**: Often refers to the **Connector Housing material** or a specific **Center-notched** keying system to prevent incorrect insertion. * **-R**: Indicates compliance with **RoHS** (Restriction of Hazardous Substances) standards. --- ### 3. Key Electronic Characteristics These parts are engineered for high-speed signal integrity and space-saving on Printed Circuit Boards (PCBs). #### A. Insulation Displacement (IDC) Technology The internal contacts are designed to pierce the insulation of a ribbon cable, creating a gas-tight connection without the need for stripping wires. This ensures: * High vibration resistance. * Fast assembly in mass production. #### B. Electrical Ratings * **Current Rating:** Usually between 0.5A to 1.0A per contact. * **Voltage Rating:** Typically 150V - 250V AC/DC. * **Insulation Resistance:** >1000 MΩ at 500V DC. --- ### 4. Common Applications * **Internal Computing:** Connecting motherboards to peripheral drives or expansion ports. * **Industrial Automation:** Signal routing between PLCs (Programmable Logic Controllers) and I/O modules. * **Medical Equipment:** High-density wiring in imaging or diagnostic tools. ---
