## Technical Analysis: A-HDF15LL-WP-R The **A-HDF15LL-WP-R** is a high-density D-Sub connector designed for rugged or industrial environments where water protection is required. It is manufactured by **Assmann WSW Components**. --- ### 1. Part Number Breakdown Understanding the nomenclature helps identify the physical and electrical characteristics: | Code Segment | Meaning | Specification | | :--- | :--- | :--- | | **A** | Manufacturer | Assmann WSW Components | | **HDF** | Type | High Density Female | | **15** | Positions | 15 Pins (standard size 1 shell) | | **LL** | Termination | Low Profile / Straight Solder Cup | | **WP** | Feature | **Waterproof** (IP67 Rated) | | **R** | Compliance | RoHS Compliant | --- ### 2. Key Specifications The following table highlights the electrical and mechanical limits of this component: | Feature | Specification | | :--- | :--- | | **Connector Type** | D-Sub, High Density | | **Number of Rows** | 3 Rows | | **Contact Type** | Socket (Female) | | **Current Rating** | 2A to 5A (typical for HD D-Sub) | | **Voltage Rating** | 250V AC/DC | | **Ingress Protection** | **IP67** (Dust tight, protected against immersion) | | **Shell Material** | Steel, Tin Plated | | **Insulator** | PBT Thermoplastic, UL94V-0 | | **Contact Plating** | Gold (Flash or selective) | --- ### 3. Electronic & Design Features * **Waterproof Sealing:** The "WP" designation indicates the presence of an O-ring and internal epoxy sealing. This prevents moisture from entering the chassis or shorting the pins in humid or wet environments. * **High-Density Layout:** While a standard D-Sub 15 has 2 rows, this High-Density version fits 15 pins into the physical shell size typically used for a 9-pin connector by using 3 rows. * **Termination Style:** The "LL" (Solder Cup) allows for manual wire soldering, making it ideal for custom cable assemblies rather than PCB mounting. * **Mounting:** Usually features #4-40 UNC threaded inserts or standoffs to ensure a secure, sealed connection with the mating cable. --- ### 4. Common Applications * **Industrial Automation:** Sensor data transmission in wash-down areas. * **Marine Electronics:** Communication interfaces exposed to salt spray. * **Outdoor Telecommunications:** External signal ports on enclosures. * **Medical Equipment:** Devices requiring frequent sterilization or liquid resistance. ---
