The **MHR26FAJ-R** is a high-density, multi-pin connector typically associated with the **MHR Series** manufactured by companies like **Honda Connectors (now part of Hirose or distributed via specialized electronics channels)**. These connectors are designed for internal equipment wiring where space is limited and reliability is critical. --- ### 1. Technical Specifications The part number breaks down into specific electrical and physical characteristics. While exact datasheets may vary by manufacturer revision, the standard parameters for the MHR series are: | Parameter | Specification | | :--- | :--- | | **Pin Count** | 26 Pins | | **Connector Gender** | Female (Receptacle) | | **Mounting Type** | Right Angle (RA) / Through-Hole | | **Pitch** | Typically 1.27mm or 2.54mm (Series dependent) | | **Contact Material** | Copper Alloy with Gold Plating | | **Current Rating** | ~1A AC/DC | | **Voltage Rating** | 250V AC (rms) | --- ### 2. Key Features * **High Reliability:** Designed for telecommunications and industrial automation where vibration resistance is necessary. * **Compact Footprint:** The "Right Angle" (FAJ) designation allows for a low profile on the Printed Circuit Board (PCB), making it ideal for stacked boards. * **Robust Housing:** Usually made of PBT (Polybutylene Terephthalate) or similar UL94V-0 rated thermoplastic. * **Gold Plating:** Ensures low contact resistance and prevents oxidation over long-term use. --- ### 3. Part Number Breakdown (Typical) Electronics manufacturers use a specific nomenclature for these parts: 1. **MHR:** Series Name (Miniature High-Reliability). 2. **26:** Number of positions/contacts. 3. **F:** Female (Socket). 4. **AJ:** Specific mechanical configuration (Right angle, long latch, or specific mounting ears). 5. **-R:** RoHS Compliant (Lead-free). --- ### 4. Common Applications * **Industrial Controllers:** Connecting PLCs to interface modules. * **Medical Equipment:** Internal data transmission between sensors and processing units. * **Telecommunications:** Used in rack-mounted switching gear. * **Legacy Computing:** Often found in specialized interface cards for older industrial PCs. ---
