The **A-HDF44PP-WP-R** is a specific electronic hardware component, typically identified as a high-density D-Sub connector manufactured by companies like **Assmann WSW Components**. Below is a detailed breakdown of its electronic and physical specifications. --- ## 1. Component Overview This part is a **44-pin High-Density D-Sub connector**. In the electronic industry, "High-Density" (HD) connectors use the same shell size as standard D-subs but pack more pins into the space by using three rows instead of two. ### Technical Specifications | Feature | Specification | | :--- | :--- | | **Connector Type** | High-Density D-Sub | | **Gender** | Female (Socket / Plug-side receptacle) | | **Number of Positions** | 44 Pins | | **Number of Rows** | 3 Rows | | **Mounting Type** | Through-Hole, Right Angle (PCB Mount) | | **Termination** | Solder | | **Shell Size** | Size 2 (Standard DB15 shell size) | --- ## 2. Key Electronic Characteristics These parameters define how the connector performs within a circuit: * **Current Rating:** Typically rated for **1A to 3A** per contact. * **Voltage Rating:** Generally rated for **250V AC/DC**. * **Contact Resistance:** Low resistance (usually < 15-30 mΩ) to ensure signal integrity. * **Insulation Resistance:** High threshold (usually > 1000 MΩ) to prevent leakage between pins. * **Dielectric Withstanding Voltage:** Can typically withstand **500V - 1000V AC** for one minute. --- ## 3. Physical & Material Composition The "WP" and "R" in the part number often refer to specific mounting hardware or RoHS compliance. ### Materials * **Contacts:** Copper alloy with selective gold plating (for superior conductivity and corrosion resistance). * **Insulator:** PBT (Polybutylene Terephthalate) Thermoplastic, UL94V-0 rated (flame retardant). * **Shell:** Steel, usually tin or nickel-plated for grounding and shielding. ### Mechanical Features * **Right Angle Orientation:** Designed to sit on the edge of a Printed Circuit Board (PCB), allowing the cable to plug in parallel to the board. * **Boardlocks / Rivets:** Includes hardware to mechanically secure the connector to the PCB before and after soldering. --- ## 4. Common Applications Due to the 44-pin density, this part is commonly used in: * **Industrial Control Systems:** Multi-signal transmission in tight spaces. * **Data Communications:** High-speed data transfer interfaces. * **Test & Measurement:** Connecting sensors to data acquisition hardware. * **Video Interfaces:** Specialized VGA-style connections (though standard VGA is 15-pin). ---
