The part number **M3SWVS-G5Y-R** identifies a specific **Flat Ribbon Cable Assembly** manufactured by **3M**. This type of component is used for internal board-to-board connections where space is limited and high signal integrity is required. --- ### 1. Component Specifications The following table breaks down the technical characteristics based on the part number nomenclature: | Feature | Specification | | :--- | :--- | | **Manufacturer** | 3M | | **Connector Type** | Socket to Card Edge | | **Number of Positions** | 50 | | **Length** | 0.500' (152.40mm, 6.00") | | **Pitch - Connector** | 0.100" (2.54mm) | | **Pitch - Cable** | 0.050" (1.27mm) | | **Color** | Multiple, Twisted Pair (Flat) | | **Shielding** | Unshielded | | **Usage** | Internal Board-to-Board or Board-to-Peripheral | --- ### 2. Breakdown of the Part Number 3M uses a systematic approach to their cable assembly numbering. Here is a general decoding of the **M3SWVS** series logic: * **M3**: Refers to the manufacturer series (3M). * **SW**: Denotes the connector type at the first end (usually a Socket). * **VS**: Denotes the connector type at the second end (usually a Card Edge connector). * **G5Y**: Represents the specific cable type (often 3602 series) and the length (G5 usually mapping to a 6-inch specification). * **R**: Indicates compliance with **RoHS** (Restriction of Hazardous Substances) standards. --- ### 3. Key Electronic Features The **M3SWVS-G5Y-R** is engineered for specific electronic environments: 1. **IDC Technology**: It utilizes **Insulation Displacement Connectors**. The metal pins pierce the cable insulation to make contact with the conductor without stripping the wire, ensuring a gas-tight, reliable connection. 2. **Twisted Pair/Flat Hybrid**: The "G" designation often refers to cable that is twisted in pairs to reduce **Crosstalk** (interference between adjacent wires) but flattened at the termination points for easy connector mass-termination. 3. **Signal Integrity**: Because it uses a 0.050" pitch cable with a 0.100" pitch connector, it is standard for older SCSI interfaces or modern industrial PLC (Programmable Logic Controller) internal wiring. --- ### 4. Typical Applications * **Industrial Automation**: Connecting sensors to a main control board via card edge slots. * **Computing**: Legacy peripheral connections or internal server backplanes. * **Test Equipment**: Connecting internal PCB modules where vibration resistance is necessary.
