The **MHR26FGJ-R** is a high-performance, shielded communication connector, typically classified as a **Mini-Delta Ribbon (MDR)** or a high-density D-sub type connector. These parts are commonly used in industrial automation, medical imaging, and telecommunications for reliable data transmission. --- ### 1. Key Technical Specifications The following table outlines the primary electronic and physical characteristics of the MHR26FGJ-R: | Parameter | Specification | | :--- | :--- | | **Number of Positions** | 26 Pins | | **Connector Style** | Receptacle (Female) | | **Mounting Type** | Through-hole, Right Angle (PCB) | | **Contact Plating** | Gold (typically 30µ" for high reliability) | | **Shell Material** | Steel or Die-cast Metal (EMI/RFI Shielding) | | **Current Rating** | ~1A per contact | | **Voltage Rating** | 150V AC/DC | --- ### 2. Core Electronic Components & Design #### A. Contact Design The "26FGJ" designation refers to a 26-pin configuration. The contacts use a **Ribbon-style** interface rather than standard pins. This design increases the surface contact area, which: * Reduces contact resistance. * Ensures stability under high-vibration environments. * Supports high-speed signaling (LVDS compatible). #### B. Shielding and EMI Protection The "R" in the suffix often indicates **RoHS compliance**, but in the context of the hardware, the outer metal shell acts as a Faraday cage. This is critical for protecting sensitive signals from electromagnetic interference (EMI) in industrial settings. #### C. PCB Interface As a **Right Angle** connector, it allows for a low-profile connection on printed circuit boards. The leads are designed for wave soldering, providing a mechanically robust bond to the board that can withstand the torque of plugging/unplugging cables. --- ### 3. Common Applications Due to its high pin density and shielding, this part is found in: 1. **Camera Link Systems:** Used in industrial machine vision cameras. 2. **Servo Drives:** Handling feedback signals between motors and controllers. 3. **Medical Equipment:** High-resolution imaging data transfer. 4. **Networking:** High-density I/O panels.
