The **A-DF15PP-WP-R** is a specific type of high-density electronic connector, typically used in industrial and computer-related hardware. It belongs to the D-Subminiature (D-Sub) family, specifically designed for high-protection environments. Below is a detailed breakdown of its electromechanical parts and technical specifications. --- ## 1. Technical Specifications Table | Feature | Specification | | :--- | :--- | | **Connector Type** | D-Sub Dual Port (Stacked) | | **Number of Positions** | 15 Pins (High Density / 3 rows) | | **Gender** | Plug (Male) / Plug (Male) | | **Mounting Type** | Through Hole, Right Angle (R/A) | | **Waterproof Rating** | WP (Waterproof - IP67 rated in most configurations) | | **Contact Plating** | Gold (R = RoHS Compliant) | | **Housing Material** | Thermoplastic (UL 94V-0) | --- ## 2. Key Component Parts ### A. The Contact Pins (The "P-P" Designation) The "PP" in the part number indicates a **Plug-Plug** configuration. These are the conductive elements made from copper alloy. * **Plating:** Usually features gold plating over nickel to prevent oxidation and ensure low contact resistance. * **Density:** Since it is a 15-position connector in a standard Shell Size E, the pins are arranged in three rows rather than two (High Density). ### B. The Waterproof Seal (WP) The "WP" suffix stands for **Waterproof**. * **O-Ring/Gasket:** The connector includes a silicone or rubber gasket that creates a seal against the chassis. * **Epoxy Sealing:** The rear of the connector where the pins meet the PCB is often sealed with a waterproof epoxy resin to prevent moisture ingress through the pins. ### C. The Right-Angle (R) Housing The "R" at the end typically denotes **Right-Angle** PCB mounting. * **Bracket:** Includes a metal mounting bracket (often with 4-40 UNC threaded nut/locks) to provide mechanical stability when plugged and unplugged. * **Stacked Design:** As a dual-port connector, it allows two separate 15-pin connections to occupy the same lateral footprint on a circuit board, saving PCB "real estate." --- ## 3. Electrical Characteristics * **Current Rating:** Typically 3A to 5A per contact. * **Voltage Rating:** Approximately 250V AC/DC. * **Dielectric Withstanding Voltage:** 1000V AC for 1 minute. * **Insulation Resistance:** 5000 MΩ Minimum. --- ## 4. Common Applications * **Industrial Automation:** Used in PLC interfaces where dust and moisture are present. * **Video Transmission:** High-density 15-pin layouts are standard for VGA signals. * **Marine Electronics:** Required for equipment exposed to high humidity or splashing water.
