The **M7EASV-S22-R** is a specific part number typically associated with a **D-Sub Cable Assembly**. This part is manufactured by **3M** and belongs to their internal wiring and connectivity solutions. --- ### 1. Technical Specifications Below are the primary technical characteristics of the M7EASV-S22-R: | Feature | Specification | | :--- | :--- | | **Connector Type** | D-Sub (High Density or Standard) | | **Number of Positions** | 09 to 37 (Configuration dependent) | | **Gender** | Receptacle to Socket (Female to Female) | | **Length** | Specific to order (Standardized cable lengths) | | **Shielding** | Shielded (Reduces EMI/RFI interference) | | **Cable Type** | Round, Jacketed (often PVC or Polyolefin) | | **Color** | Multiple / Variable (standard is usually beige or gray) | --- ### 2. Breakdown of the Part Number While 3M part numbers are complex, the code generally follows this logic: * **M7:** Usually designates the series or specific cable geometry. * **EASV:** Refers to the connector style and orientation (e.g., Socket, Straight exit). * **S22:** Often indicates the pin count or the specific internal wire gauge (AWG). * **R:** Indicates compliance with **RoHS** (Restriction of Hazardous Substances) standards. --- ### 3. Key Components 1. **Contact Plating:** Typically uses gold plating on the contact surface to ensure high conductivity and resistance to corrosion over time. 2. **Strain Relief:** The assembly includes molded or mechanical strain relief to prevent the wires from snapping at the connector interface during bending. 3. **Shell Material:** Usually steel with tin or zinc plating for grounding and durability. --- ### 4. Common Applications * **Industrial Automation:** Connecting PLC units to human-machine interfaces (HMI). * **Telecommunications:** Used in data transmission racks and cabinet wiring. * **Computing:** Legacy peripheral connections and RS-232 serial communication. * **Medical Equipment:** High-reliability signal routing between diagnostic modules. ---
