The part number **M3SWVS-ZAY-R/K** refers to a high-quality ribbon cable assembly produced by **3M**. This specific configuration is part of the 3M standard molded cable assembly line, typically used for internal board-to-board connections or interfacing with headers. --- ### 1. Technical Specifications Table | Feature | Description | | :--- | :--- | | **Manufacturer** | 3M | | **Connector Type** | Socket to Socket (Female to Female) | | **Number of Positions** | 10 to 64 (Variable by specific dash code) | | **Pitch (Connector)** | 0.100" (2.54mm) | | **Pitch (Cable)** | 0.050" (1.27mm) | | **Mounting Type** | Free Hanging (In-Line) | | **Cable Type** | Flat Ribbon, Gray | | **Shielding** | Unshielded | --- ### 2. Breakdown of the Part Number Logic To understand the electronic components involved, we can break down the alphanumeric code: * **M3**: 3M Manufacturer code. * **S**: Represents the **Socket** connector type. * **W**: Indicates the use of **Wire** (Ribbon cable). * **VS**: Specifies the **Standard** series or specific strain relief configuration. * **ZAY**: This is a specific internal 3M code for the **Length** and **Color** (usually gray ribbon cable with a red edge for Pin 1 identification). * **R/K**: Indicates compliance with **RoHS** standards (R) and specific packaging or assembly revisions (K). --- ### 3. Key Electronic Components The assembly consists of three primary elements: #### A. Insulation Displacement Connectors (IDC) The ends are terminated with 3M 3000 Series (or equivalent) sockets. These use **BeCu (Beryllium Copper)** contacts for high reliability and multi-point contact with header pins. #### B. 28 AWG Stranded Ribbon Cable The cable typically consists of tinned copper conductors. The stranded nature allows for flexibility within electronic enclosures without the risk of metal fatigue or "work hardening" found in solid core wires. #### C. Strain Relief The "S" and "V" designations often imply the presence of a molded or clip-on strain relief. This protects the delicate IDC connection points from being pulled apart during maintenance or vibration. --- ### 4. Common Applications * **Industrial Controls:** Connecting PLCs to HMI screens. * **Computing:** Legacy drive interfaces or internal motherboard-to-front-panel headers. * **Prototyping:** Connecting microcontrollers (like Arduino or Raspberry Pi) to expansion shields.
