The **M2PHSH-11-R** typically refers to a specific configuration of a **Pin Header Connector**, often part of a series used for board-to-board or wire-to-board connections. Based on standard electronic component nomenclature (common to brands like Adam Tech or similar manufacturers), here is the detailed breakdown. ### 1. Component Overview The M2PHSH-11-R is a **Male Pin Header**, characterized by its 2.00mm pitch. These are essential for creating modular electronic assemblies, allowing PCBs to be stacked or connected via ribbon cables. --- ### 2. Technical Specifications | Feature | Specification | | :--- | :--- | | **Pitch** | 2.00 mm (0.079") | | **Number of Pins** | 11 Pins | | **Row Configuration** | Single Row (S) | | **Orientation** | Horizontal / Right Angle (H) | | **Mounting Type** | Through-Hole | | **Plating** | Tin or Gold (Reflected by "R" suffix in some catalogs) | | **RoHS Status** | Compliant (R) | --- ### 3. Part Number Deciphering (Typical) To understand the electronic properties, we can break down the alphanumeric code: * **M2PH**: **M**iniature **2**.00mm **P**in **H**eader series. * **S**: **S**ingle Row (denotes one line of pins). * **H**: **H**orizontal (Right-angle orientation relative to the PCB). * **11**: The specific **Pin Count** (11 positions). * **R**: Often denotes **R**oHS compliance or a specific **R**ight-angle mounting style. --- ### 4. Electrical and Mechanical Characteristics #### Electrical * **Current Rating:** Typically 1.5A to 2.0A per contact. * **Voltage Rating:** ~250V AC/DC. * **Contact Resistance:** $\le$ 20 m$\Omega$. * **Insulation Resistance:** $\ge$ 1000 M$\Omega$. #### Mechanical / Material * **Insulator Material:** High-temperature thermoplastic (e.g., PBT or Nylon 6T), suitable for wave soldering. * **Contact Material:** Copper Alloy (Brass or Phosphor Bronze). * **Durability:** Usually rated for 50 to 100 mating cycles. --- ### 5. Common Applications * **PCB Stacking:** Connecting a daughterboard to a motherboard. * **Peripheral Connection:** Linking LCD screens, sensors, or buttons to a main controller. * **Prototyping:** Used frequently on development boards (like ESP32 or specialized Arduino shields) that require a low-profile 2.0mm footprint rather than the standard 2.54mm.
