The part number **6HDD15PBY99R40X** corresponds to a high-density D-Subminiature connector, typically manufactured by **CONEC**. These connectors are used for high-reliability signal transmissions in industrial, medical, and telecommunications equipment. --- ## 1. Technical Specifications Below is a breakdown of the key physical and electrical characteristics of this specific component: | Feature | Specification | | :--- | :--- | | **Connector Type** | High-Density D-Sub (HD D-Sub) | | **Number of Positions** | 15 Pins | | **Gender** | Plug (Male) | | **Mounting Type** | Through-hole, Right Angle (90°) | | **Contact Material** | Copper Alloy | | **Plating** | Gold (often flash or specific microns depending on grade) | | **Shell Material** | Steel, Tin-plated | | **Termination** | Solder | | **Spacing** | High-density layout (3 rows) | --- ## 2. Part Number Decoder (Conec Logic) To understand exactly what this part consists of, we can break down the alphanumeric code: * **6H**: Refers to High-Density D-Sub series. * **DD**: Denotes the shell size (standard "E" size shell, but with "D" density). * **15**: The pin count (15 contacts squeezed into the footprint of a standard 9-pin shell). * **P**: Gender is **Plug** (Male pins). * **BY**: Refers to the specific mounting hardware (e.g., threaded inserts or brackets). * **99R40X**: These are manufacturer-specific suffixes indicating the contact plating thickness, the angle of the mounting bracket (90 degrees), and the specific packaging or assembly revision. --- ## 3. Key Electronic Functions ### Signal Integrity High-density connectors allow for more signal paths in a smaller footprint. This is essential for modern PCBs where space is at a premium. ### Mechanical Stability The "Right Angle" design is intended for PCB edge mounting. The **99R40X** suffix usually implies the presence of a "Boardlock" or specialized mounting bracket that ensures the connector remains grounded and mechanically secure under vibration. ### Durability The use of Gold plating on the contacts prevents oxidation over time, ensuring low contact resistance and a high number of mating cycles (insertion and removal). --- ## 4. Typical Applications * **VGA Interfaces:** 15-pin HD D-Subs are the standard for VGA video connections. * **Industrial Controls:** Used for PLC (Programmable Logic Controller) communication ports. * **Medical Devices:** Reliable signal transmission for diagnostic imaging equipment. * **Aerospace:** Used in non-flight critical avionics due to their robust mechanical locking mechanisms.
