Based on the part number description, the **M2MS-F-R/Q** typically refers to a high-density, modular connector assembly often used in telecommunications and data networking. These are commonly associated with the **Metral** or **Hard Metric (HM)** series. --- ## Technical Overview The **M2MS-F-R/Q** is a specialized modular connector component. Below is a breakdown of its primary electronic and mechanical characteristics: ### 1. Key Specifications Table | Feature | Specification Details | | :--- | :--- | | **Series** | Metral / 2mm Hard Metric (HM) | | **Pitch** | 2.00 mm | | **Mounting Type** | Through-hole / Press-fit (Solderless) | | **Orientation** | Right Angle (Female/Receptacle) | | **Row Configuration** | 5-Row (Standard) | | **Shielding** | Integrated Ground/Shielding options (indicated by /Q) | --- ### 2. Part Number Breakdown Understanding the suffix and prefix codes helps identify the exact electronic application: * **M2MS**: Refers to the Metral 2mm system, designed for high-density backplane or midplane applications. * **F**: Indicates a **Female** (Receptacle) connector. * **R**: Generally signifies a **Right Angle** orientation, used for daughtercard-to-backplane connections. * **Q**: This specific suffix often refers to **Special Shielding** or a specific **Pin Assignment/Selection** (sometimes used for high-signal integrity applications to reduce crosstalk). --- ### 3. Electronic & Mechanical Functions 1. **Signal Integrity**: The 2mm pitch allows for a high concentration of signals in a small PCB area. The "Q" variant is optimized for low noise and minimal interference. 2. **Press-Fit Technology**: These parts usually use "Eye-of-the-Needle" compliant pins. This eliminates the need for soldering, which reduces thermal stress on the PCB and allows for easier repairs. 3. **Modular Design**: These connectors are "stackable" end-to-end without loss of position, allowing engineers to build custom-length backplane interfaces. --- ### 4. Typical Applications These parts are industrial-grade and are usually found in: * **Telecommunications**: Switching equipment and base stations. * **Computing**: High-end servers and data storage arrays. * **Industrial Controls**: PLCs (Programmable Logic Controllers) where vibration resistance and high pin count are required.
