The **M3SVS-F2-R** is a specific part number typically associated with **3M’s series of IDC (Insulation Displacement Connector) Ribbon Cable Assemblies**. This part belongs to the **3M™ 3000 Series** and is designed for high-density, reliable board-to-board or cable-to-board interconnections. --- ## 1. Technical Specifications The part number follows a specific nomenclature that defines its electronic and physical characteristics: | Feature | Specification | | :--- | :--- | | **Connector Type** | IDC Ribbon Cable Assembly | | **Number of Positions** | Typically 3 (based on M3**S**VS prefix) | | **Connector A** | Socket (Female) | | **Connector B** | Socket (Female) | | **Pitch** | 0.100" (2.54 mm) | | **Shielding** | Unshielded | | **RoHS Status** | Compliant (indicated by -R suffix) | --- ## 2. Key Electronic Components ### A. The IDC Contacts The "heart" of the connector is the **Insulation Displacement Contact**. * **Material:** Usually a Copper Alloy with Gold plating over Nickel. * **Function:** The contact pierces the insulation of a flat ribbon cable to make a gas-tight connection with the internal conductor without needing to strip the wire. ### B. The Ribbon Cable * **Gauge:** Typically compatible with 26 AWG or 28 AWG stranded wire. * **Voltage Rating:** Generally rated for **300V**. * **Current Rating:** Approximately **1A** per contact (depending on temperature rise). ### C. Housing (Insulator) * **Material:** Glass-filled Polyester (PBT). * **Dielectric Withstanding Voltage:** 1000 Vrms at sea level. * **Insulation Resistance:** > $1 \times 10^9 \Omega$ at 500 Vdc. --- ## 3. Application Use Cases The M3SVS-F2-R is commonly used in environments where modularity and space-saving are required: 1. **Internal PC Wiring:** Connecting motherboards to peripheral headers. 2. **Industrial Controls:** Signal routing between PLCs and interface panels. 3. **Embedded Systems:** Connecting JTAG debuggers or displays to a PCB. --- ## 4.
