The **M2PHS2L-12-R2/N** is a specific part number typically associated with high-density power distribution systems, often used in telecommunications, server racks, or industrial power management. Based on the nomenclature, this is generally categorized as a **Modular Power Distribution Plug/Connector** or a **Power Header System**. --- ### 1. Technical Specifications Overview | Feature | Description | | :--- | :--- | | **Type** | Power Header / High-Current Connector | | **Circuit Count** | 12-Position (indicated by the "-12-") | | **Orientation** | Right Angle (indicated by "R2") | | **Mounting Style** | Through-hole PCB Mount or Panel Mount | | **Plating** | Tin or Selective Gold (standard for high-reliability) | | **Configuration** | 2-Row Layout (PHS2 - Power Header Series 2-row) | --- ### 2. Breakdown of the Part Number The alphanumeric code provides specific details regarding the physical and electrical characteristics of the component: * **M2**: Often refers to the series generation or the mechanical interface size. * **PHS**: **P**ower **H**eader **S**ystem. Designed for high-current applications compared to standard signal headers. * **2L**: Refers to a "2-Level" or "2-Row" pin configuration. * **12**: Total number of circuits/pins. * **R2**: **R**ight-angle orientation. The "2" may specify a specific offset or lead length for the pins. * **N**: Typically denotes "Natural" color (white/off-white plastic) or a specific material rating (e.g., Nylon 66). --- ### 3. Electronic & Mechanical Properties #### High Current Handling These connectors are engineered with thick copper alloy pins to handle significant amperage (often between 5A to 15A per circuit, depending on the wire gauge and housing pitch). #### Heat Dissipation The housing is usually made of high-temperature thermoplastic (UL94V-0 rated) to withstand the heat generated by high current flow without deforming. #### Polarization & Locking * **Polarization:** The housing is keyed so the mating connector cannot be inserted upside down. * **Locking:** Includes a ramp or friction-lock mechanism to ensure the connection remains secure under vibration. --- ### 4. Common Applications * **Server Power Supplies:** Distributing DC power from a backplane to individual blades. * **Industrial Automation:** Connecting PLCs to high-power actuators. * **Telecommunications:** Powering base station equipment. ---
