The **M2CEC-23505-R2** is a specialized high-density electrical connector, commonly associated with the automotive industry, specifically within the Ford Motor Company supply chain. It belongs to the **Molex CMC (Compact Modular Connector)** family, designed for high-performance Powertrain and Body Electronics applications. --- ### 1. General Specifications This part is a high-density, sealed hybrid connection system. The "Hybrid" designation means it can carry both signal and power currents simultaneously. | Feature | Description | | :--- | :--- | | **Manufacturer Family** | Molex CMC (or equivalent Tier 1 supplier) | | **Pin Count** | 32-Way (Standard configuration for this series) | | **Sealing** | IP6K9K (High-pressure wash resistant) | | **Operating Temp** | -40°C to +125°C | | **Housing Material** | PBT / Glass-filled Polymer | --- ### 2. Physical Components The connector is comprised of several distinct electronic and mechanical parts: 1. **Housing (The Body):** A matte-sealed, high-temperature plastic frame that provides the structural support and insulation for the terminals. 2. **TPA (Terminal Position Assurance):** A secondary locking mechanism (usually colored differently, like Red or Blue) that ensures the metallic terminals are fully seated and cannot back out under vibration. 3. **Mat Seal:** A silicone-based perimeter seal that prevents moisture and dust from entering the rear wire entries. 4. **Lever/Slide Mechanism:** Because of the high pin density, these connectors use a mechanical lever to reduce the "mating force" required to plug it into the Engine Control Unit (ECU). --- ### 3. Terminal Interface (The Electrical Path) The M2CEC series typically utilizes a mix of different terminal sizes to handle varying electrical loads: * **0.64mm Terminals:** Used for low-current data signals (CAN Bus, Sensor inputs). * **1.50mm / 2.80mm Terminals:** Used for higher current loads (Power supply, Grounding, Actuator control). ### 4. Common Applications * **ECU/PCM Interface:** The primary connection point for Engine Control Modules. * **Transmission Controllers:** Managing electronic shifting and solenoids. * **Lighting Control Modules:** High-density wiring for LED arrays and adaptive lighting. --- ### 5. Technical Identification (Cross-Reference) In the automotive world, part numbers often have "Global" equivalents. The **M2CEC-23505-R2** corresponds to specific Molex engineering series: * **Molex Series 64319:** Often used for the 32-circuit headers. * **Molex Series 64320:** Often used for the 48-circuit headers.
