The **AS4CT-S15-R** is a specific part number belonging to the **AS4CT series** of high-performance connectors, typically manufactured by companies like **Hirose Electric** or specialized automotive component suppliers. These are generally used in high-speed transmission and automotive signal integrity applications. ### 1. General Specifications The AS4CT series is designed to handle automotive-grade environments while maintaining high-speed data integrity. | Feature | Specification (Typical) | | :--- | :--- | | **Type** | Board-to-Wire / Interface Connector | | **Number of Positions** | Varies by sub-model (S15 indicates 15 positions/pins) | | **Data Rate** | Supports high-speed transmission (e.g., LVDS, USB) | | **Voltage Rating** | Typically 30V - 100V AC/DC | | **Current Rating** | 0.5A to 1.0A per contact | | **Operating Temperature** | -40°C to +105°C (Automotive Grade) | --- ### 2. Breakdown of the Part Number While naming conventions can vary slightly by manufacturer, the code usually breaks down as follows: * **AS4**: Series identifier (Automotive High-Speed Serial). * **CT**: Connector Type (often indicates a Crimp or Terminal style). * **S**: Socket/Female housing. * **15**: Number of contacts (15 pins). * **R**: Packaging suffix (typically indicates "Reel" for automated assembly). --- ### 3. Key Electronic Characteristics These parts are engineered for reliability in "noisy" electronic environments. #### A. Signal Integrity The internal contact structure is designed to minimize impedance mismatch. This is crucial for protocols such as: * **FPD-Link / GMSL**: Used for automotive cameras and displays. * **Ethernet**: For vehicle diagnostic systems. #### B. Shielding and EMI The "R" and "CT" variants often feature enhanced metal shielding to prevent Electromagnetic Interference (EMI) from affecting sensitive vehicle sensors. #### C. Mechanical Robustness * **Locking Mechanism**: Usually features a positive lock (audible click) to prevent disconnection due to vehicle vibration. * **Polarization**: The housing is keyed to prevent incorrect insertion (mating). --- ### 4. Typical Applications * **Infotainment Systems**: Connecting the head unit to the dashboard display. * **ADAS (Advanced Driver Assistance Systems)**: Connecting radar or LIDAR sensors to the ECU. * **Telematics Control Units**: High-speed data transfer for GPS and LTE modules. ---
