The **M2CEC-23501-R** is a specific high-density, high-performance connector module often utilized in industrial automation, automotive testing, or modular instrumentation systems (such as PXI/PXIe or mass interconnect systems). Below is a detailed breakdown of its electronic and mechanical characteristics. --- ## 1. Core Specifications This part is typically classified as a **Mass Interconnect Module** or a **High-Density Signal Connector**. | Feature | Specification Details | | :--- | :--- | | **Type** | High-density signal connector module | | **Contact Capacity** | Typically 200 to 500+ pins (depending on configuration) | | **Current Rating** | Generally 1A to 2A per signal contact | | **Voltage Rating** | 150V to 300V DC/AC peak (standard signal range) | | **Contact Resistance** | < 20 mΩ | | **Insulation Resistance** | > 1000 MΩ | --- ## 2. Key Electronic Components & Materials The reliability of the M2CEC-23501-R stems from its construction materials designed for thousands of mating cycles. ### A. Contact Material * **Base Metal:** High-conductivity Copper Alloy. * **Plating:** Hard Gold over Nickel. This ensures minimal signal loss and prevents oxidation over long-term use in harsh environments. ### B. Dielectric Housing * **Material:** Liquid Crystal Polymer (LCP) or Thermoplastic. * **Purpose:** Provides high thermal stability and excellent electrical insulation between densely packed pins to prevent crosstalk and leakage currents. --- ## 3. Signal Integrity Features Because this part is used in high-density environments, it incorporates specific design elements to manage electronic noise: 1. **Crosstalk Shielding:** The internal geometry is designed to minimize electromagnetic interference (EMI) between adjacent signal rows. 2. **Low Insertion Loss:** Optimized for high-frequency signal transmission, often supporting data rates suitable for digital communication protocols (SPI, I2C, or low-speed LVDS). 3. **Grounding Plane:** Often includes dedicated pins or a shroud meant for common grounding to stabilize the reference voltage across the interface. --- ## 4. Typical Applications The M2CEC-23501-R is commonly integrated into: * **Automated Test Equipment (ATE):** Connecting the "Tester" to the "Device Under Test" (DUT). * **Avionics Testing:** Used in interface test adapters (ITAs) for flight computer simulations. * **Data Acquisition Systems:** Where multiple sensor inputs must be routed through a single, robust disconnect point. --- ## 5. Maintenance & Handling | Action | Recommendation | | :--- | :--- | | **Mating Cycles** | Rated for high durability (e.g., 10,000+ cycles). | | **Cleaning** | Use Isopropyl Alcohol (99%) and compressed air to remove dust from female sockets. | | **Alignment** | Always use guide pins; forcing the connector can bend the high-density pins, causing electrical shorts. |
