The **M2PHSL-15D-R** is a specific part number typically associated with high-density, vertical, surface-mount (SMT) pin headers. These components are used to create electrical connections between a Printed Circuit Board (PCB) and a female socket or ribbon cable connector. --- ### ## Technical Specifications & Characteristics Below is a breakdown of the typical electronic and physical attributes for this part: | Feature | Specification | Description | | :--- | :--- | :--- | | **Connector Type** | Pin Header | Male pins arranged in a grid. | | **Pitch** | 2.00 mm | The center-to-center distance between pins. | | **Number of Pins** | 15 Pins (Dual Row) | Often configured as 2x8 or similar depending on the specific series suffix. | | **Mounting Type** | Surface Mount (SMT) | Designed to be soldered directly to the surface pads of a PCB. | | **Orientation** | Vertical / Straight | Pins stand 90 degrees relative to the PCB surface. | | **Contact Plating** | Gold or Tin | Typically features selective gold plating for high conductivity and oxidation resistance. | | **Body Material** | High-Temp Thermoplastic | Rated for reflow soldering temperatures (e.g., LCP or Nylon 6T). | --- ### ### Key Components and Design Features 1. **Contact Pins:** Usually made of Copper Alloy (Brass or Phosphor Bronze). The "R" in the suffix often indicates **RoHS Compliance** or specific **Reel Packaging** for automated pick-and-place machines. 2. **Insulator:** The plastic housing holds the pins in precise alignment. High-temperature plastics are used to ensure the part does not melt during the SMD reflow oven process. 3. **Polarization / Shrouding:** Depending on the exact sub-series, these headers may be "shrouded" (boxed in) to prevent accidental reverse connection or "unshrouded" (exposed pins). 4. **Solder Tabs:** Being an SMT component, the "tails" of the pins are bent or shaped to sit flat on the PCB solder paste. --- ### ### Application Use-Cases * **Embedded Systems:** Connecting a Microcontroller board (like an ESP32 or specialized ARM board) to a sensor shield. * **Industrial Controls:** Interfacing PLC modules where space is limited and 2.00mm pitch is preferred over the standard 2.54mm (0.1"). * **Consumer Electronics:** Internal board-to-board connections in laptops, monitors, or smart home devices. --- ### ### Schematic Representation In EDA software (like Altium, KiCad, or Eagle), the part is represented as a simple header. ```text [ J1 ] (1) o o (2) (3) o o (4) (5) o o (6) ... ...
