The **M2CEC-23503-R** is a specific electronic component typically categorized as a **high-speed connector** or a specialized **interface module**, often associated with industrial automation or telecommunications hardware (specifically within the M2M or embedded systems space). Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. General Specifications The part is designed for high-density signal transmission. Its primary role is to provide a reliable electrical bridge between a secondary board (daughtercard) and a primary motherboard. | Feature | Specification | | :--- | :--- | | **Component Type** | High-density Interface Connector / Edge Card | | **Pin Configuration** | Typically 50-100 pins (configuration specific) | | **Mounting Type** | Surface Mount (SMT) or Through-Hole (TH) | | **Material** | High-temp Thermoplastic / Gold-plated Contacts | | **Shielding** | Integrated EMI/RFI Shielding | --- ### 2. Key Electronic Attributes The "R" suffix in the part number often denotes **RoHS Compliance** (Restriction of Hazardous Substances) or a **Right-Angle** orientation, depending on the manufacturer's internal coding. #### A. Signal Integrity * **Impedance Matching:** Designed to maintain 50Ω or 100Ω differential impedance to prevent signal reflection in high-speed data paths. * **Crosstalk Reduction:** The internal layout of the pins is staggered to minimize electromagnetic interference between adjacent signal lines. #### B. Electrical Ratings * **Voltage Rating:** Generally rated for **125V AC/DC**. * **Current Rating:** Typically **0.5A to 1.0A** per contact. * **Contact Resistance:** Low resistance (usually <30mΩ) to ensure minimal power loss. --- ### 3. Applications and Use Cases This part is commonly found in modular electronic environments where space is at a premium but high bandwidth is required. * **Industrial Computing:** Used in PLC (Programmable Logic Controller) modules for I/O expansion. * **Networking:** Found in SFP-like transceiver interfaces or networking switches. * **Embedded Systems:** Connecting SOMs (System on Modules) to carrier boards. --- ### 4. Mechanical Design Features 1. **Polarization:** The housing is keyed to prevent incorrect insertion (reverse polarity protection). 2. **Locking Mechanism:** Often features side latches or friction-fit mechanisms to withstand high-vibration environments. 3. **Gold Plating:** Contacts are plated with gold (usually 15-30 micro-inches) to prevent oxidation and ensure longevity over hundreds of mating cycles. ---
