The part number **DAO2V2S500G8KLF** refers to a high-performance **D-Subminiature (D-Sub) Connector** manufactured by **Amphenol ICC (FCI)**. Specifically, it belongs to the "Power D-Sub" or "Combo D-Sub" family, designed to combine signal and high-power transmission within a single connector shell. --- ### 1. Technical Specifications | Parameter | Details | | :--- | :--- | | **Manufacturer** | Amphenol ICC (FCI) | | **Connector Type** | D-Sub Mixed Layout (Power + Signal) | | **Shell Size** | A | | **Contact Layout** | 2V2 (2 Power Contacts, 0 Signal Contacts) | | **Gender** | Receptacle (Socket/Female) | | **Termination Style** | Straight Solder (PCB Mount) | | **Mounting Type** | Through Hole | | **Plating** | Gold (8µin or standard flash depending on batch) | | **RoHS Status** | Lead-Free / Compliant (LF suffix) | --- ### 2. Part Number Breakdown To understand the electronic capabilities of this component, we can decode the nomenclature: * **DA**: Represents the shell size (Size A). * **O**: Indicates the specific series or mounting option (often signifies a standard straight version). * **2V2**: The contact arrangement. "2V2" means there are **2 cavities** specifically designed for **Power** (Vertical) contacts, and no signal pins. * **S**: Female gender (Socket). * **500**: Mounting accessory code (Standard hole/no special brackets). * **G**: Contact plating code (usually Class 2 or specific gold thickness). * **8**: Performance level or specific mechanical variation. * **KLF**: Indicates Lead-Free (RoHS compliant) and specific packaging/industrial standards. --- ### 3. Key Features and Usage #### High Current Capability Unlike standard D-Subs that handle 1-5 Amps, the power contacts used in the 2V2 layout are typically rated for **20A to 40A** per contact, depending on the specific power terminals installed. #### Hybrid Versatility While this specific model is 2V2 (only power), the series is designed to allow engineers to mix coax, high-voltage, and power contacts in a standard D-Sub footprint, saving PCB real estate. #### Industrial Durability * **Steel Shells:** Usually tin-plated with dimples for grounding/EMI shielding. * **Insulator:** High-temperature thermoplastic (UL94V-0 rated). * **Applications:** Telecommunications base stations, industrial robotics, power supply units, and medical medical equipment. ---
