The part number **DAO2V2P500M8KLF** refers to a high-reliability, high-performance D-Subminiature connector, typically manufactured by **Amphenol ICC (FCI)**. This specific part belongs to the **Power D-Sub** series, designed for applications requiring a mix of signal and high-power delivery. ### Technical Specifications Breakdown | Feature | Specification | | :--- | :--- | | **Series** | Power D-Sub (Mixed Layout) | | **Shell Size** | A | | **Contact Layout** | 2V2 (2 Power Contacts, 0 Signal) | | **Contact Gender** | Male (Plug / Pins) | | **Termination Style** | Straight PCB Mount (Solder) | | **Mounting Type** | Through-hole | | **Plating** | Gold over Nickel (F class / High durability) | | **Lead-Free Status** | RoHS Compliant (LF suffix) | --- ### Component Features & Construction #### 1. Hybrid Contact Layout (2V2) The "2V2" designation indicates that this connector uses a standard Shell Size A (normally used for 15-pin high-density or 9-pin standard D-subs) but is populated with **two large power cavities**. In this specific configuration, there are no signal pins, only two power pins. #### 2. Power Handling * **Current Rating:** Depending on the specific power contacts used, these connectors can typically handle between **20A and 40A** per contact. * **Voltage Rating:** Generally rated for 300V RMS. #### 3. Material and Plating * **Shell:** Steel, typically tin-plated with dimples (to improve grounding and EMI/RFI shielding). * **Insulator:** High-temperature thermoplastic (UL94V-0 rated), capable of withstanding wave soldering processes. * **Contacts:** Copper alloy with gold plating in the mating area to ensure low contact resistance and long-term reliability against corrosion. #### 4. Mechanical Mounting * **Straight Leads:** The pins are designed to go straight down into a Printed Circuit Board (PCB). * **Hardware:** The "M8" or similar codes in the suffix often denote the specific mounting hardware attached to the flange (such as threaded inserts or clinchnuts) to secure the connector to a chassis or panel. --- ### Common Applications * **Industrial Automation:** Powering motor controllers and actuators. * **Telecommunications:** DC power distribution in base stations. * **Medical Equipment:** Reliable power interfaces for diagnostic machinery. * **Power Supplies:** Serving as the main input/output interface for modular power units.
