The **M2PHSH-1B-R2/N** is a specialized high-performance connector typically used in industrial automation, medical equipment, or high-reliability computing. It belongs to a category of **M2-style multi-pin board-to-board or cable-to-board interconnects**. --- ### 1. Technical Specifications Breakdown The following table outlines the typical electrical and mechanical characteristics for this component series: | Parameter | Specification (Typical) | | :--- | :--- | | **Connector Type** | High-Density Multi-Pin Header | | **Pitch** | 2.0mm or 1.27mm (Series Dependent) | | **Contact Material** | Phosphor Bronze or Copper Alloy | | **Plating** | Gold (R2 designation often implies selective gold) | | **Current Rating** | 1.0A to 2.0A per contact | | **Voltage Rating** | 125V AC/DC | | **Operating Temp** | -40°C to +105°C | | **Mounting Type** | Surface Mount (SMT) or Through-Hole (TH) | --- ### 2. Part Number Nomenclature While exact codes vary by manufacturer (such as JST, Hirose, or specialized vendors), the suffix breakdown usually follows this logic: * **M2PHSH**: The series identifier. "M2" often refers to the metric sizing, while "PHSH" denotes a **P**lug/Header with **S**hrouded **H**ousing. * **1B**: Refers to the physical configuration or row count (1 row, Type B orientation). * **R2**: Indicates the plating thickness or reel packaging style (e.g., 2u" Gold or specific Tape & Reel dimensions). * **N**: Typically signifies "Natural" color (off-white/beige) or "Nylon" material base. --- ### 3. Key Electronic Features #### Shrouded Design The "SH" in the name indicates the connector is **shrouded**. This provides: - **Polarization:** Prevents the user from plugging the cable in upside down. - **Pin Protection:** The plastic walls protect the delicate pins from bending during handling or mating. #### High Reliability The **R2 gold plating** ensures low contact resistance and prevents oxidation over long periods, making it suitable for environments with vibration or thermal cycling. #### SMT Compatibility The base material is usually a high-temperature thermoplastic (like LCP), allowing the part to survive **Reflow Soldering** processes without warping. --- ### 4. Application Examples - **Internal PCB Interconnects:** Connecting a mainboard to a daughterboard. - **Display Interfaces:** Routing signals to LCD panels. - **Sensor Arrays:** Consolidating multiple low-voltage sensor signals into a single port.
