The **M2PHS2W-BB-R** is a specific type of electronic hardware component, categorized as a **Pin Header** or **PCB Connector**. These components are fundamental in electronics for creating board-to-board or wire-to-board connections. Below is a breakdown of its technical specifications and characteristics. ### 1. Product Identification | Parameter | Description | | :--- | :--- | | **Product Type** | Pin Header (Male) | | **Mounting Type** | Through-Hole (THT) | | **Pitch** | 2.00mm (Distance between pin centers) | | **Orientation** | Straight / Vertical | | **Rows** | Dual Row (2 Rows) | --- ### 2. Physical Characteristics The part number follows a standard nomenclature used by manufacturers (often associated with brands like **Adam Tech** or similar high-density connector specialists): * **M2PH**: Refers to the series (2.00mm Pitch Header). * **S**: Denotes the pin length/style (Standard). * **2W**: Indicates a "Dual Row" configuration. * **BB**: Refers to the plating (typically **Gold Flash** or Selective Gold on the contact area and Tin on the tails). * **R**: Generally stands for **RoHS Compliant**, ensuring the part is lead-free and environmentally safe. ### 3. Technical Specifications Typical electrical and mechanical ratings for this class of connector include: | Feature | Typical Value | | :--- | :--- | | **Current Rating** | 1.0A to 2.0A AC/DC | | **Voltage Rating** | 250V AC/DC | | **Contact Resistance** | 20mΩ Max | | **Insulation Resistance** | 1000MΩ Min | | **Dielectric Strength** | 500V AC for 1 minute | | **Material** | Nylon 6T or PBT (UL94V-0) | | **Operating Temp** | -40°C to +105°C | --- ### 4. Common Applications * **PCB Stacking:** Connecting two parallel circuit boards. * **Jumper Settings:** Used with "Shunts" or "Jumpers" to configure hardware settings. * **Interface Port:** Serving as a connection point for ribbon cables (IDC) or female socket headers. * **Prototyping:** Frequently found on development boards (like Arduino or ESP32 variants) for GPIO access. ### 5. Installation Note When soldering the **M2PHS2W-BB-R**, ensure the PCB hole diameter is correctly sized (usually ~0.80mm to 0.90mm) to accommodate the square pins. Because it is a 2.00mm pitch header, it is smaller than the "standard" 2.54mm (0.1 inch) headers found on basic hobbyist electronics.
