The **M2SES-1AB-R** is a specific electronic component, typically categorized as a **Micro-USB 2.0 Connector**. It is designed for Surface Mount Device (SMD) applications, commonly found in mobile devices, charging ports, and peripheral connectivity. --- ### 1. Technical Specifications Below are the primary electrical and physical characteristics of the M2SES-1AB-R: | Feature | Specification | | :--- | :--- | | **Connector Type** | Micro-USB Type B (Receptacle) | | **USB Version** | USB 2.0 | | **Mounting Type** | Surface Mount (SMD / SMT) | | **Orientation** | Right Angle (Horizontal) | | **Number of Contacts** | 5 Pins | | **Current Rating** | ~1.0A to 1.8A (Variable by manufacturer) | | **Voltage Rating** | 30V AC/DC | | **Durability** | ~10,000 Mating Cycles | --- ### 2. Key Internal Components The part consists of several critical materials and design features to ensure electrical integrity: 1. **Contact Pins:** Usually made of a copper alloy with **Gold plating** over Nickel. Gold is used to prevent oxidation and ensure a low-resistance connection over thousands of plug-in cycles. 2. **Housing/Insulator:** High-temperature thermoplastic (Liquid Crystal Polymer or LCP). This material is chosen because it can withstand the heat of **reflow soldering** without melting or warping. 3. **Shielding (Shell):** Stainless steel or brass with tin/nickel plating. This provides structural strength and acts as a Faraday cage to reduce Electromagnetic Interference (EMI). 4. **Solder Tabs:** These provide mechanical stability, anchoring the connector to the PCB so it doesn't rip off when a cable is inserted or removed. --- ### 3. Pinout Configuration As a standard Micro-USB Type B, the 5-pin layout is defined as follows: | Pin Number | Name | Function | | :--- | :--- | :--- | | 1 | VCC | +5V Power Supply | | 2 | D- | Data Minus | | 3 | D+ | Data Plus | | 4 | ID | Identification (OTG mode) | | 5 | GND | Ground | --- ### 4. Common Applications * **Consumer Electronics:** Smartphones, tablets, and digital cameras. * **Power Solutions:** Battery charging circuits for portable power banks. * **Embedded Systems:** Programming ports for microcontrollers (like ESP32 or Arduino-based boards). * **Peripherals:** Computer mice, keyboards, and wireless headset charging. ---
