The **DA15SAM1-R3** is a specific model of a D-Subminiature (D-Sub) connector. It is widely used in electronic hardware for serial data, power supply, and signal interfaces. --- ### ## Technical Specifications The part number follows a standardized naming convention for D-Sub connectors. Here is the breakdown of its physical and electrical characteristics: | Feature | Specification | | :--- | :--- | | **Connector Type** | D-Subminiature | | **Shell Size** | DA (Standard 15-pin shell size) | | **Number of Positions** | 15 Pins | | **Gender** | Male (Plug) | | **Orientation** | Right Angle | | **Mounting Type** | Through-Hole (PCB Mount) | | **Termination** | Solder | | **Contact Material** | Copper Alloy (typically Gold plated over Nickel) | --- ### ### Key Electronic Components The DA15SAM1-R3 consists of several critical sub-parts that ensure electrical integrity: 1. **Insulator (Dielectric):** Usually made of UL94V-0 rated thermoplastic (like PBT). This prevents short circuits between the 15 pins. 2. **Contacts (Pins):** These are the conductive elements. The "Male" designation means these are solid pins that fit into a female socket. The "R3" designation often refers to a specific lead length or plating thickness variant. 3. **Metal Shell:** Typically steel with tin or zinc plating. It provides EMI/RFI shielding and structural grounding when connected to the chassis. 4. **Boardlocks/Harpoons:** These are the metal tabs on the bottom that hold the connector securely to the PCB before and during the soldering process. --- ### ### Application Use Cases This specific connector is commonly found in the following electronic environments: * **Legacy Video:** Used in some older VGA or specialty video transmission hardware. * **Industrial Controls:** Often used for RS-232, RS-422, or RS-485 communication interfaces in PLC (Programmable Logic Controller) systems. * **DAQs:** Data acquisition systems where 15 discrete signals need to be routed to a single board-to-cable interface. * **Power Supplies:** Used as a multi-pin low-voltage power delivery port. --- ### ### Electrical Ratings (Typical) * **Current Rating:** ~3A to 5A per contact. * **Voltage Rating:** 250V AC/DC. * **Dielectric Withstanding Voltage:** 1000V AC for 1 minute. * **Insulation Resistance:** 5000 Megohms minimum.
