## M6SWVS-E6-R: Technical Overview The **M6SWVS-E6-R** is a specific part number belonging to the **M6** series of flat cable connectors, typically manufactured by **3M** or under licensed standards. This component is a specialized **Socket Connector** designed for IDC (Insulation Displacement Contact) termination. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Connector Type** | IDC Flat Cable Socket | | **Number of Positions** | 6 Positions (2x3 configuration) | | **Pitch** | 2.54mm (0.100") | | **Mounting Type** | Cable Mount (IDC) | | **Contact Material** | Copper Alloy | | **Plating** | Tin (indicated by the "-R" RoHS compliance) | | **Color** | Gray (Standard for the M6 series) | --- ### 2. Breakdown of the Part Number Understanding the nomenclature helps identify the physical attributes: * **M6**: Refers to the series (Standard 2.54mm IDC Socket). * **S**: Indicates "Socket" (Female connector). * **6**: Number of pins/circuits. * **W**: Usually denotes the presence of a "Center Bump" or "Polarization Key" to prevent reverse insertion. * **V**: Vertical orientation/entry. * **S**: Strain Relief (Includes a plastic clip to hold the cable securely). * **E6**: Internal manufacturing code for contact plating/housing style. * **R**: **RoHS Compliant** (Lead-free). --- ### 3. Electronic & Mechanical Characteristics #### A. Insulation Displacement Contact (IDC) The "E6" variant uses "U-shaped" contacts. When the flat ribbon cable is pressed into the connector, the contacts pierce the insulation to make a gas-tight connection with the internal copper wires. This eliminates the need for stripping individual wires. #### B. Polarization & Keying The **W** in the part number signifies a **Military/Central Polarization** bump. This ensures the connector can only be plugged into a shrouded header in one specific direction, preventing short circuits or reversed signals. #### C. Strain Relief The **S** suffix indicates the inclusion of a strain relief clip. This is a plastic bar that snaps over the folded ribbon cable, transferring mechanical stress away from the delicate IDC terminations to the connector body. --- ### 4. Common Applications * **Internal Computer Bus:** Connecting motherboards to legacy peripherals. * **Industrial Control Systems:** Linkage between PLCs and HMI panels. * **Prototyping:** Used extensively with 6-pin ISP (In-System Programming) headers for AVR/Arduino microcontrollers. ---
