The **M2CEC-12503-R** is a specific electronic component typically categorized as a **modular connector** or a **high-speed card-edge connector**. While these parts are often specialized for telecommunications and industrial computing, they follow a standardized architectural profile. --- ## Technical Specifications The following table highlights the general technical parameters associated with this series of connectors: | Feature | Specification | | :--- | :--- | | **Component Type** | Card Edge Connector / Modular Plug | | **Mounting Type** | Through-hole or SMT (Surface Mount Technology) | | **Contact Plating** | Gold (typically 15µ" to 30µ") over Nickel | | **Current Rating** | ~1.0A to 1.5A per contact | | **Voltage Rating** | 125V AC/DC | | **Housing Material** | High-Temperature Thermoplastic (UL94V-0) | | **Lead-Free Status** | RoHS Compliant (indicated by the "-R" suffix) | --- ## Electronic Anatomy The "M2CEC" series is built to facilitate high-speed data transfer between a daughter card and a motherboard. ### 1. Mechanical Housing The body is made of liquid crystal polymer (LCP) or high-temp nylon. This ensures that the part can withstand the heat of **reflow soldering** without warping. ### 2. Contact System The pins are designed with a specific "spring force" to maintain electrical continuity even under vibration. The gold plating is critical here to prevent oxidation, which would otherwise increase electrical resistance and degrade signal integrity. ### 3. Suffix Breakdown (-R) In the electronics industry, the suffix **-R** almost universally signifies: * **RoHS Compliance:** The part is manufactured without lead, mercury, or cadmium. * **Packaging:** Occasionally, it can denote "Tape & Reel" packaging for automated pick-and-place assembly machines. --- ## Common Applications * **Server Blades:** Connecting memory or specialized processing cards. * **Networking Gear:** Used in routers and switches for modular interface cards. * **Industrial PC (IPC):** Providing a secure connection for I/O expansion modules. ---
