The **MHO+66TGG-R** is a specific part number typically associated with **D-Sub connectors** or specialized interface components used in telecommunications and high-density industrial electronics. Based on the nomenclature, this part belongs to a family of high-performance connectors. Below is a breakdown of its technical characteristics. --- ### 1. General Specifications | Feature | Description | | :--- | :--- | | **Component Type** | D-Subminiature Connector / High-Density Interface | | **Contact Gender** | Female (Socket) / Receptacle | | **Pin Count** | 66 Pins (High Density) | | **Mounting Type** | Through-hole / Right Angle PCB Mount | | **Orientation** | 90-degree (Right Angle) | | **Plating** | Gold (G) over Nickel | --- ### 2. Key Features and Materials * **High-Density Configuration:** Unlike standard D-subs (which usually have 9 to 50 pins), the 66-pin configuration utilizes a high-density layout (3 rows) to save PCB real estate while maintaining high signal counts. * **Shell Material:** Usually constructed from cold-rolled steel with tin or zinc plating to provide EMI/RFI shielding. * **Insulator:** Made of high-temperature thermoplastic (UL 94V-0 rated), allowing it to withstand wave soldering processes. * **Contacts:** Phosphor bronze or copper alloy base, ensuring high conductivity and mechanical durability. --- ### 3. Part Number Breakdown (Typical) While manufacturers vary slightly, the "MHO+66TGG-R" code generally translates as follows: 1. **MHO+**: Series prefix (Often associated with specific brands like *NorComp* or *Kycon* variants). 2. **66**: The number of positions/contacts. 3. **T**: Termination type (e.g., Through-hole). 4. **GG**: Gold plating thickness (often indicates Gold Flash or 15-30u" Gold). 5. **R**: RoHS Compliant (Lead-free). --- ### 4. Typical Applications These connectors are engineered for environments where space is limited but high signal integrity is required: * **Telecommunications:** Network switches and routers. * **Industrial Automation:** PLCs (Programmable Logic Controllers) and CNC machinery. * **Medical Equipment:** Imaging and diagnostic devices. * **Aerospace:** Control systems and interface panels. --- ### 5. Technical Ratings * **Current Rating:** ~2A to 3A per contact. * **Voltage Rating:** 250V AC/DC. * **Operating Temperature:** -55°C to +105°C. * **Dielectric Withstanding Voltage:** 1000V AC for 1 minute.
