The part number **M3SWVS-GDY-R** identifies a specific configuration of a D-Sub cable assembly manufactured by **3M**. This component is designed for industrial and computing applications where reliable data transmission is required. --- ## 1. Technical Specifications Table The following table breaks down the core characteristics of this assembly based on the 3M part numbering system: | Feature | Specification | Description | | :--- | :--- | :--- | | **Manufacturer** | 3M | High-reliability industrial manufacturer | | **Connector Type** | D-Sub (Socket to Socket) | Female-to-Female connection | | **Number of Positions** | 37 Pins | High-density signal transmission | | **Length** | 10.00' (3.05m) | Total cable span | | **Shielding** | Shielded | Protects against EMI/RFI interference | | **Cable Type** | Ribbon, Gray | Multi-conductor flat ribbon cable | | **Contact Finish** | Gold | 30.0µin (0.76µm) thickness for corrosion resistance | | **Pitch** | 0.050" (1.27mm) | Standard pitch for ribbon cable D-Subs | --- ## 2. Component Breakdown ### A. Connector Structure (M3) The assembly utilizes 3M's molded D-Sub connectors. These are typically **IDC (Insulation Displacement Contact)** style, which allows the connector to be pressed onto the ribbon cable without stripping individual wires. ### B. Material Composition * **Insulation:** Usually reinforced thermoplastic (UL 94V-0 rated). * **Contacts:** Copper alloy base with gold plating in the mating area to ensure low electrical resistance and durability over many mating cycles. * **Shell:** Steel with tin plating, providing a robust grounding path and physical protection for the pins. ### C. Shielding and Strain Relief The "S" and subsequent codes in the part number often denote specific features: * **Shielding:** The cable is wrapped in a foil or braid to prevent crosstalk and external noise from corrupting data. * **Strain Relief:** The molded ends include strain relief to prevent the cable from tearing away from the connector under mechanical stress. --- ## 3. Common Applications * **Industrial Automation:** Connecting PLCs to HMI panels or sensors. * **Legacy Computing:** Interfacing with older peripheral devices that require 37-pin parallel communication. * **Test and Measurement:** Routing multiple signal lines from a data acquisition box to a computer interface. ---
