The **M2AS1-6232-R2/CE** is a specialized electronic component, typically categorized as a high-density, high-performance backplane or board-to-board connector assembly, often used in telecommunications or industrial computing environments (such as ATCA or CompactPCI architectures). --- ### 1. Component Overview This part is engineered for high-speed signal integrity and robust mechanical connection. Below is a breakdown of its primary electronic and physical characteristics: | Attribute | Specification | | :--- | :--- | | **Type** | Board-to-Board / High-Speed Backplane Connector | | **Configuration** | Multi-row, High-density pins | | **Mounting Type** | Press-fit (Solderless) or Through-hole | | **Contact Material** | Copper Alloy with Gold over Nickel Plating | | **Application** | Data centers, Network switches, Industrial servers | --- ### 2. Key Electronic Features #### High-Speed Differential Signaling The internal geometry of the pins is designed to minimize crosstalk and impedance mismatch. This allows the part to handle high-frequency signals required for protocols like PCIe, Ethernet (10G/40G), or InfiniBand. #### Signal Integrity (SI) Design * **Shielding:** Integrated ground planes or shielding plates between signal rows to prevent electromagnetic interference (EMI). * **Impedance Control:** Tight tolerances on pin spacing ensure a consistent 85Ω or 100Ω differential impedance. #### Power and Grounding The "CE" suffix often denotes compliance with specific European standards or specific pin assignments for grounding. These connectors usually feature a mix of: 1. **Signal Pins:** For data transmission. 2. **Power Pins:** Thickened contacts capable of handling higher currents (Amps). 3. **Grounding Pins:** Longer pins (First-Mate Last-Break) to ensure electrostatic discharge (ESD) protection during hot-swapping. --- ### 3. Mechanical & Structural Parts * **Insulator Housing:** Made of high-temperature thermoplastic (e.g., LCP - Liquid Crystal Polymer) to withstand lead-free soldering temperatures. * **Press-fit "Eye-of-the-Needle":** The pins use a compliant tail design. This allows the connector to be pressed into the PCB without soldering, creating a cold-weld connection that is highly resistant to vibration. * **Alignment Keys:** Built-in plastic guides to prevent "blind-mating" errors where pins might be bent due to misalignment. --- ### 4. Technical Nomenclature (Breakdown) While specific to the manufacturer's catalog (often linked to brands like ERNI, Harting, or TE Connectivity), the code usually breaks down as follows: * **M2AS:** Series designation (Metric 2mm High-Speed). * **1-6232:** Specific configuration (Number of rows, pins, and housing style). * **R2:** Revision or RoHS 2 compliance status. * **CE:** Customer-specific variant or European Conformity marking.
