The part number **FUDS-4W4-R.SLASHQ** refers to a high-current, mixed-layout **D-Sub (Subminiature) connector**, typically from the "F-Series" manufactured by companies like **FCT (a Molex company)**. The suffix ".SLASHQ" usually indicates specialized packaging or a specific plating/quality requirement for industrial or military-grade applications. --- ### 1. Technical Specification Breakdown Based on standard nomenclature for this series, here is the breakdown of the electronic components and features: | Feature | Description | | :--- | :--- | | **Connector Type** | D-Subminiature (Mixed Layout) | | **Shell Size** | Size 2 (Standard D-Sub shell size for 15-pin equivalents) | | **Contact Layout** | **4W4** (4 Power/Coaxial cavities, no signal pins) | | **Gender** | Socket / Female (denoted by "S") | | **Mounting Style** | Right-Angle (denoted by "R") | | **Contact Type** | High Power (capable of 10A to 40A depending on specific insert) | --- ### 2. Key Electronic Components #### A. The Shell (Housing) The "FU" prefix indicates a specific shell material, usually **Zinc-plated steel** or **Tin-plated steel**. It provides EMI/RFI shielding and physical grounding to the chassis. #### B. 4W4 Insert Configuration The "4W4" designation is critical. Unlike a standard 15-pin D-sub, this part has: * **4 Large Cavities:** Designed to hold specialized "Coded" or "Power" contacts. * **Zero Signal Pins:** This connector is purely for power delivery or high-frequency signals. #### C. High Power Contacts These connectors are designed to house gold-plated copper alloy contacts. Because it is a "Right-Angle" (R) version, the contacts are typically soldered directly into a PCB (Printed Circuit Board). --- ### 3. Applications This specific part is used in hardware where space is limited but high current is required: * **Power Supplies:** Delivering DC power to server blades. * **Industrial Automation:** Connecting motor controllers. * **Telecommunications:** Base station power distribution. --- ### 4.
