The **A-DF15LL-WP-R** is a specialized electronic component primarily used in industrial and telecommunications hardware. It is a **D-Subminiature connector** designed for environmental resilience. Below is a detailed breakdown of its specifications and features. --- ### 1. Technical Specifications The part number follows standard industry nomenclature for high-density or waterproof D-sub connectors. | Feature | Specification | | :--- | :--- | | **Connector Type** | D-Subminiature | | **Pin Count** | 15 Pins | | **Gender** | Female (Socket) | | **Mounting Type** | Through-hole / Right Angle (depending on PCB layout) | | **Waterproof Rating** | IP67 / IP68 (WP designation) | | **Contact Plating** | Gold (R designation often implies RoHS compliance) | | **Shell Material** | Steel with Nickel or Tin plating | --- ### 2. Key Part Number Breakdown Understanding the alphanumeric code helps identify the specific variant of the component: * **A-DF:** Series prefix indicating a D-Sub Female connector. * **15:** The number of positions (pins). * **LL:** Refers to the physical footprint or "Long Lead" / Locking mechanism style. * **WP:** **Water-Proof**. This indicates the connector includes a silicone O-ring or potting to prevent moisture ingress. * **R:** **RoHS Compliant**. This confirms the part is manufactured without hazardous substances like lead. --- ### 3. Structural Features This component is built for "harsh environment" applications. * **Sealing:** It features a specialized frame and a rear-sealing gasket to maintain a vacuum or water-tight seal when mounted to a chassis. * **Durability:** Designed for high mating cycles, often featuring gold-plated copper alloy contacts to prevent oxidation. * **Shielding:** The metal shell provides EMI/RFI protection, which is critical for data integrity in noisy industrial environments. --- ### 4. Common Applications Due to the **WP (Waterproof)** rating, this part is rarely used in standard office computers. Instead, it is found in: * **Marine Electronics:** GPS and sonar equipment. * **Industrial Automation:** Control panels exposed to wash-down cycles. * **Outdoor Telecommunications:** Signal boxes and cellular base stations. * **Medical Equipment:** Devices requiring frequent sterilization or liquid resistance. ---
