It belongs to the family of **High-Speed Mezzanine Connectors**. --- ### Technical Specifications & Composition Below are the typical electronic characteristics for this series: | Feature | Specification | | :--- | :--- | | **Component Type** | Mezzanine Connector (Plug/Socket) | | **Number of Positions** | 140 Pins (based on the 14001 designation) | | **Pitch** | 0.50mm - 0.80mm (typical for M2 series) | | **Mounting Type** | Surface Mount Technology (SMT) | | **Plating** | Gold (Flash or selective) over Nickel | | **Data Rate Support** | High-speed differential signaling (up to 10+ Gbps) | --- ### Key Electronic Parts and Design Features The assembly of the M2CEC-14001-R2 consists of several critical sub-components that ensure electrical integrity: #### 1. Signal Contacts * **Material:** Usually Phosphor Bronze or Beryllium Copper for high conductivity and elasticity. * **Function:** Provides the physical electrical path between two Printed Circuit Boards (PCBs). * **Design:** Engineered for low insertion force to prevent pin damage during blind mating. #### 2. Insulator Housing * **Material:** High-temperature Liquid Crystal Polymer (LCP) or Thermoplastic. * **Function:** Prevents short circuits between the 140 pins and maintains the structural alignment (pitch) of the contacts. * **Durability:** Designed to withstand Lead-Free Reflow soldering temperatures (up to 260°C). #### 3. Grounding Shields (Integral) * The "CEC" designation often refers to **Controlled Impedance** or **Enhanced Cross-talk** reduction. * The part includes internal metal shielding to minimize Electromagnetic Interference (EMI) and maintain 100-ohm differential impedance for high-speed data transmission. #### 4. Solder Tabs / Pegs * **Mechanical Reinforcement:** Metal tabs on the sides of the connector provide mechanical stability to the PCB, ensuring the electrical joints do not snap under vibration or thermal expansion. --- ### Applications * **Automotive Grade:** Used in Advanced Driver Assistance Systems (ADAS) or infotainment modules. * **Computing:** Connecting daughter cards to carrier boards in blade servers. * **Telecommunications:** High-bandwidth networking equipment.
