The **M2PHSH-A12-R2** is a specialized electronic component, typically classified as a high-density, high-speed connector often used in telecommunications, server hardware, or industrial computing environments. Below is a detailed breakdown of its electronic and physical characteristics. --- ### 1. General Specifications This part is a **12-pin, 2.0mm pitch, dual-row male header/connector**. It is designed for board-to-board or wire-to-board applications where space is limited but high connectivity density is required. | Feature | Specification | | :--- | :--- | | **Pitch** | 2.0mm (0.079 inches) | | **Pin Count** | 12 Pins (6x2 Configuration) | | **Mounting Type** | Through-Hole (THT) or SMT (depending on specific R2 variant) | | **Orientation** | Right-Angle or Vertical (typically Right-Angle for 'R2') | | **Contact Material** | Copper Alloy | | **Plating** | Selective Gold or Tin-Lead | --- ### 2. Key Electronic Components & Materials #### A. Insulator Housing The "body" of the connector is typically made of **High-Temperature Thermoplastic** (like LCP or PBT). This allows the part to withstand lead-free soldering processes (Reflow or Wave) without deforming. #### B. Contact Terminals The pins are the functional heart of the part: * **Conductivity:** High-grade copper alloy ensures low electrical resistance. * **Plating:** Gold plating is often used on the contact area to prevent oxidation and ensure signal integrity over thousands of mating cycles. #### C. Polarization & Shrouding The "HSH" in the part number often refers to a **Shrouded Header**. The shroud protects the pins from bending and ensures that the mating cable can only be inserted in the correct orientation (Keying). --- ### 3. Electrical Performance Limits | Parameter | Typical Value | | :--- | :--- | | **Current Rating** | 1.5A to 2.0A per contact | | **Voltage Rating** | 250V AC/DC | | **Insulation Resistance** | 1000 MΩ Min. | | **Contact Resistance** | 20 mΩ Max. | | **Dielectric Withstanding** | 500V AC for 1 minute | --- ### 4. Application Use-Cases * **Embedded Systems:** Connecting daughterboards to main motherboards. * **PLC Units:** Used in programmable logic controllers for industrial automation. * **Data Servers:** High-density signal routing for cooling fans or sensor arrays.
