The part number **M3SWVS-B6Y-R/Q** refers to a high-quality ribbon cable assembly manufactured by **3M**. This specific configuration is part of their 3000 series connector system, typically used for internal board-to-board or peripheral connections. --- ### 1. Part Number Breakdown To understand the electronic components, we must decode the naming convention: | Segment | Code | Description | | :--- | :--- | :--- | | **Series** | **M3** | 3M standard metric/standard cable assembly series. | | **Connector A** | **S** | Socket (Rectangular Connector). | | **Cable Type** | **W** | Color-coded / Multi-color ribbon cable. | | **Connector B** | **V** | PCB Pin Header / Vertical Mount. | | **Pin Count** | **B** | Represents 6 contacts (specific to this sub-series mapping). | | **Length** | **6Y** | Cable length (approx. 0.5 feet / 6 inches). | | **Features** | **R/Q** | Polarizing keys and Strain Relief specifications. | --- ### 2. Technical Specifications The assembly consists of three primary electronic components integrated into one unit: #### A. The Ribbon Cable * **Pitch:** 0.050" (1.27 mm) or 2 mm depending on the specific sub-series (Standard 3M pitch). * **Conductors:** Stranded tinned copper for flexibility and conductivity. * **Insulation:** PVC, color-coded for easy identification of pin assignments. #### B. The Socket Connector (End A) * **Type:** IDC (Insulation Displacement Connector). * **Contact Material:** Copper Alloy. * **Plating:** Gold over Nickel (ensures low contact resistance and prevents oxidation). * **Locking:** Includes a center bump polarization to prevent incorrect insertion. #### C. The PCB Header (End B) * **Mounting:** Vertical through-hole or SMT (Surface Mount). * **Housing:** High-temperature thermoplastic (suitable for soldering). * **Security:** Usually includes latches or a friction fit to ensure the cable does not vibrate loose. --- ### 3. Key Electronic Characteristics * **Current Rating:** Typically 1A per contact. * **Voltage Rating:** 30V to 300V (AC/DC) depending on specific insulation thickness. * **Temperature Range:** -20°C to +105°C. * **Insulation Resistance:** > 1 x 10⁹ $\Omega$ at 500 VDC. --- ### 4. Common Applications This part is frequently found in: 1. **Industrial Controls:** Connecting a main logic board to a front panel display. 2. **Computing:** Interconnecting hard drive controllers or legacy peripheral ports. 3. **Prototyping:** Used with headers on PCBs for modular hardware development.
