The **M2PHS2H-16A-R** is a specific model of a **Pin Header Connector**, typically used in PCB (Printed Circuit Board) assembly to establish electrical connections between boards or to peripherals. Below is a breakdown of its electronic specifications and characteristics. --- ### 1. General Specifications | Feature | Description | | :--- | :--- | | **Component Type** | Pin Header (Male) | | **Pitch** | 2.0mm (Distance between centers of pins) | | **Number of Pins** | 16 Pins | | **Row Configuration** | Dual Row (2x8 layout) | | **Mounting Type** | Through-Hole (THT) or SMT (Specific to suffix) | | **Orientation** | Right-Angle (Horizontal) | --- ### 2. Key Electronic & Material Characteristics #### A. Electrical Ratings * **Current Rating:** Generally rated for **1.5A to 2.0A** per contact, depending on the base material. * **Voltage Rating:** Typically rated up to **250V AC/DC**. * **Contact Resistance:** Low resistance (usually < 20mΩ) to ensure minimal signal loss. * **Insulation Resistance:** High threshold (usually > 1000MΩ) to prevent leakage between adjacent pins. #### B. Physical Construction * **Contact Material:** Usually a copper alloy (like Brass or Phosphor Bronze) for high conductivity. * **Plating:** The "R" or specific suffix often denotes **Gold Flash** or **Tin plating**. Gold is preferred for high-reliability applications to prevent oxidation. * **Insulator Material:** High-temperature thermoplastic (e.g., PBT or Nylon 6T), capable of withstanding wave soldering temperatures. --- ### 3. Part Number Breakdown (Typical) While naming conventions vary slightly by manufacturer (such as Sullins, Samtec, or generic brands), the code generally breaks down as follows: * **M2P:** 2.0mm Pitch series. * **HS:** Header Strip / High Specification. * **2H:** Dual Row, Horizontal (Right-Angle). * **16A:** 16 total positions (Pins). * **R:** Often indicates **RoHS Compliance** or **Right-Angle** orientation. --- ### 4. Common Applications * **Embedded Systems:** Connecting sensor modules to a main microcontroller board. * **Computing:** Internal jumpers or peripheral headers. * **Industrial Controls:** Signal routing in compact enclosures where vertical space is limited (hence the right-angle design).
