The **M2PHS2H-15B-R** is a specific electronic component belonging to the **electromechanical connector** category, specifically a high-density, high-speed board-to-board or cable-to-board header. Below is a detailed breakdown of its electronic and mechanical specifications. --- ### 1. General Specifications This part is typically used in industrial automation, telecommunications, and automotive electronics where space-saving and signal integrity are critical. | Feature | Specification | | :--- | :--- | | **Component Type** | Pin Header (Male) | | **Pitch** | 2.0mm (Standard for high-density applications) | | **Number of Pins** | 15 Pins (Typically arranged in 2 rows) | | **Mounting Type** | Surface Mount (SMT) or Through-Hole (THT) depending on suffix | | **Orientation** | Right-Angle (indicated by the 'R' suffix) | --- ### 2. Electrical Characteristics The electrical performance is defined by the conductivity of the pins and the insulation properties of the housing. * **Current Rating:** Generally rated for **1.5A to 2.0A** per contact. * **Voltage Rating:** Typically **250V AC/DC**. * **Contact Resistance:** $\le$ 20 m$\Omega$ (initial); ensures minimal signal loss. * **Insulation Resistance:** $\ge$ 1000 M$\Omega$; prevents leakage between adjacent pins. * **Dielectric Withstanding Voltage:** 500V AC for one minute. --- ### 3. Material and Physical Construction The materials chosen for this part are designed to withstand high-temperature soldering processes (like Reflow). 1. **Housing:** Usually made of **LCP (Liquid Crystal Polymer)** or **PBT (Polybutylene Terephthalate)**. These are high-temperature plastics (UL94V-0 rated). 2. **Contact Material:** Phosphor Bronze or Brass for high conductivity and flexibility. 3. **Plating:** * **Contact Area:** Gold plating (often 1u", 3u", or 15u") to prevent oxidation and ensure reliable connection. * **Solder Tail:** Tin plating for better solderability. --- ### 4. Part Number Breakdown (Nomenclature) While exact numbering varies by manufacturer (such as JST, Molex, or generic brands), the code generally follows this logic: | Segment | Meaning | | :--- | :--- | | **M2** | Series identifier (often refers to 2.0mm pitch) | | **PH** | Pin Header | | **S2H** | Square Pin / Double Row / High profile | | **15** | Total pin count (15 positions) | | **B** | Black housing (standard color) | | **R** | **Right Angle** orientation | --- ### 5. Application Use Cases * **PCB Stacking:** Connecting two parallel or perpendicular circuit boards. * **Signal Routing:** Passing low-voltage data signals between a control board and a display or sensor. * **Industrial Controllers:** Used in PLCs (Programmable Logic Controllers) for modular connections.
