The **M2ADS-B22-R** is a specific variant of high-performance connectors, typically associated with the **M2 series** (often manufactured by companies like **Harwin**). These components are designed for high-reliability applications where space is limited but vibration resistance is critical. --- ### 1. General Specifications This part is a high-density, 2.00mm pitch connector often used in aerospace, defense, and industrial automation. | Feature | Specification | | :--- | :--- | | **Pitch** | 2.00mm (0.0787") | | **Configuration** | Dual Row (2x11 or similar depending on series suffix) | | **Mounting Type** | Through-hole or SMT (Surface Mount) | | **Orientation** | Right-Angle (indicated by the "-R") | | **Plating** | Gold on contact area, Tin on solder tails | --- ### 2. Breakdown of the Part Number While specific naming conventions vary by manufacturer, the code generally follows this logic: * **M2**: The product series family (High-reliability 2mm pitch). * **AD**: Connector style (often denotes a specific shrouded or male/female type). * **S**: Mounting style (e.g., SMT or Through-hole). * **B**: Number of rows or specific polarising features. * **22**: Total number of contacts (likely 11 pins per row). * **R**: **Right-Angle** orientation (the connector sits 90 degrees to the PCB). --- ### 3. Key Electronic Characteristics These parts are engineered to perform under harsh electrical and environmental conditions: * **Current Rating:** Typically 2A to 3A per contact. * **Voltage Rating:** Up to 800V AC/DC. * **Contact Resistance:** Usually < 20mΩ. * **Insulation Resistance:** > 1000MΩ. * **Operating Temperature:** Wide range, usually **-55°C to +125°C**. --- ### 4. Common Applications Due to its robust design, the M2ADS-B22-R is found in: 1. **UAVs and Drones:** For flight controller to peripheral connections. 2. **Military Avionics:** Internal HUD or communication boards. 3. **Medical Equipment:** High-density portable diagnostic tools. 4. **Robotics:** Sensor data transmission in vibrating environments. --- ### 5. Footprint Example (Pseudo-Code) If you are designing a PCB (e.g., in KiCad or Altium), your footprint logic would follow a grid-based system: ```cpp // Schematic Pin Mapping (22 Pins) Row_A: Pins 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21 Row_B: Pins 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22 // Mechanical Data Pitch_X = 2.00mm; Pitch_Y = 2.00mm; Hole_Diameter = 0.80mm; // For through-hole variants ``` ---
