The **M2PHSH-1B-R** is a specific electronic component, typically categorized as a high-density, high-performance connector or specialized pin header used in industrial and automotive electronics. Below is a detailed breakdown of its electronic parts, specifications, and characteristics. --- ### 1. General Specifications The part number generally refers to a **Surface Mount (SMT) or Through-Hole Pin Header** with specific plating and housing materials designed for reliability in harsh environments. | Feature | Description | | :--- | :--- | | **Component Type** | Male Pin Header / Shrouded Connector | | **Mounting Style** | Surface Mount (SMT) or Through-Hole (Dependent on specific sub-series) | | **Pitch** | Typically 2.0mm or 2.54mm (industry standard) | | **Number of Rows** | Single Row (indicated by "1B") | | **RoHS Status** | Compliant (indicated by "-R") | --- ### 2. Key Electronic Parts & Materials The performance of the M2PHSH-1B-R is defined by three primary material components: #### A. Contact Pins (Conductive Part) * **Material:** Usually Phosphor Bronze or Brass. * **Plating:** Gold flash or selective gold plating on the contact area to prevent oxidation and ensure low contact resistance. * **Function:** Provides the electrical path between the PCB and the mating female connector. #### B. Insulator Housing * **Material:** High-temperature thermoplastic (e.g., LCP - Liquid Crystal Polymer or Nylon 6T/9T). * **Function:** Mechanically holds the pins in place and provides electrical isolation between adjacent pins. It is designed to withstand infrared (IR) or vapor phase reflow soldering temperatures. #### C. Shroud / Shielding * **Type:** Shrouded (The "SH" in the part number). * **Function:** The plastic housing extends around the pins to ensure "polarization" (preventing incorrect orientation during mating) and to protect the pins from physical damage or bending. --- ### 3. Electrical & Mechanical Characteristics | Parameter | Typical Value | | :--- | :--- | | **Current Rating** | 1.0A to 3.0A per contact | | **Voltage Rating** | 250V AC/DC | | **Contact Resistance** | < 20 mΩ | | **Insulation Resistance** | > 1000 MΩ | | **Operating Temperature** | -40°C to +105°C | --- ### 4. Application Use Cases Due to its robust construction, this part is commonly found in: 1. **Automotive ECU Modules:** For internal signal routing. 2. **Industrial Control Systems:** Used on PLCs for modular connectivity. 3. **Consumer Electronics:** High-reliability power or data headers in appliances.
