The **MAH26FBD-R** is a high-performance, D-subminiature connector manufactured by **Positronic**. It belongs to the **High-Density (HD) series**, specifically designed for aerospace, industrial, and military-grade applications where reliability and space-efficiency are critical. --- ### 1. Key Technical Specifications | Feature | Specification | |:---|:---| | **Connector Type** | High-Density D-Subminiature | | **Number of Contacts** | 26 | | **Gender** | Female (Socket) | | **Contact Size** | #22 | | **Current Rating** | ~5 Amperes per contact | | **Termination Style** | Right Angle (Board Mount) | | **Locking System** | Fixed Female Jackscrews (Board Mount) | --- ### 2. Physical & Electronic Characteristics #### A. Contact Configuration The "26" in the part number indicates a high-density layout. While a standard D-sub shell of this size (Size 2) would usually hold 15 contacts, this high-density variant fits **26 contacts** into the same footprint by using smaller pins and tighter spacing. #### B. Mounting and Orientation The **"-R"** suffix typically denotes a **Right Angle** orientation. This means the connector is designed to be soldered onto a Printed Circuit Board (PCB) so that the mating face sits at a 90-degree angle to the board surface. #### C. Materials and Durability * **Insulator:** Usually glass-filled diallyl phthalate or polyester, providing high dielectric strength. * **Contacts:** Precision machined copper alloy with gold plating for superior conductivity and corrosion resistance. * **Shell:** Steel or brass with zinc or tin plating (often with a clear chromate finish). --- ### 3. Applications Due to its high density and rugged construction, the MAH26FBD-R is commonly found in: * **Avionics:** Flight control systems and communication racks. * **Medical Equipment:** High-signal-count diagnostic machines. * **Telecommunications:** Network routers and server interfaces. * **Industrial Automation:** Heavy-duty control panels. --- ### 4. Part Number Breakdown (Generic Positronic Logic) * **MAH:** High-Density Machined D-Sub Series. * **26:** Number of Pins/Sockets. * **F:** Female (Socket) contacts. * **B:** Board-mount (Right Angle). * **D:** Specific mounting/locking hardware (e.g., Jackscrews). * **-R:** RoHs Compliant or specific Right-angle revision.
