The **MTS2** (Miniature Terminal System 2) is a specialized electronic connector series frequently used in automotive electronics, specifically within high-density wiring harnesses. It is engineered for low-current signal transmissions where space is limited but high reliability is required. Below is an overview of the electronic parts and specifications related to the MTS2 system. --- ### 1. Key Components of the MTS2 System The system is comprised of three primary physical components: | Part Type | Description | Material/Plating | | :--- | :--- | :--- | | **Female Terminal** | The socket contact that accepts the male pin. Features a high-pressure contact spring. | Copper Alloy (Tin or Gold plated) | | **Male Tab** | The pin header (usually 0.64mm). Often integrated into a PCB header or wire-to-wire housing. | Brass/Copper Alloy | | **Housing** | The plastic shell that holds the terminals. Includes a secondary lock (TPA). | PBT (Polybutylene Terephthalate) | --- ### 2. Electrical Specifications Electronic performance is critical for MTS2 as it often handles sensitive sensor data or ECU (Electronic Control Unit) signals. * **Current Rating:** Typically **5A maximum** (subject to wire gauge and ambient temperature). * **Voltage Drop:** Low resistance design, usually $< 3m\Omega$ (initial). * **Operating Temperature:** -40°C to +125°C (Automotive Grade). * **Dielectric Strength:** Capable of withstanding **1000V AC** for 1 minute. * **Insulation Resistance:** $> 100M\Omega$ at 500V DC. --- ### 3. Mechanical & Physical Features ### Terminal Geometry The MTS2 uses a **0.64mm (0.025 inch)** tab size. This smaller footprint allows for more circuits in a smaller connector body compared to standard 1.5mm or 2.8mm systems. ### Locking Mechanisms 1. **Primary Lock:** A lance or "tang" on the terminal that clicks into the housing. 2. **TPA (Terminal Position Assurance):** A secondary red or yellow plastic clip that ensures all terminals are fully seated; if a terminal is pushed back, the TPA will not close. 3. **CPA (Connector Position Assurance):** An optional lock on the outer housing to prevent the plug from vibrating loose from the socket. --- ### 4. Common Applications Due to its electronic stability, the MTS2 is found in: * **ADAS Modules:** Camera and radar signal connections. * **Infotainment:** Low-voltage data lines for displays. * **Body Control Modules (BCM):** Handling door locks, lighting signals, and window switches. ---
