Based on technical nomenclature typically associated with high-frequency RF connectors and automotive-grade electronics, the part number **M2AS1-A233-R2/Q** refers to a specific configuration of a **FAKRA (Fachnormenausschuss Kraftfahrzeug) Connector**. These connectors are industry standards in the automotive sector for RF (Radio Frequency) signals. --- ### 1. Component Overview The **M2AS1** series generally denotes a miniature, high-performance SMB-based connector housing. The suffixes provide details on the coding (color/mechanical keying) and the packaging format. | Specification | Detail | | :--- | :--- | | **Connector Type** | FAKRA II / SMB | | **Gender** | Male (Plug) | | **Orientation** | Right-Angle (R2) | | **Mounting** | PCB Mount (Through-Hole or SMT depending on layout) | | **Coding** | Code A (Black) | | **Impedance** | 50 Ohms | --- ### 2. Breakdown of the Part Number * **M2AS1**: The base series identifier for the FAKRA connector generation. * **A**: This represents the **Mechanical Keying/Color Code**. Code "A" is standard **Black** and is typically reserved for **Radio/General Audio** applications. * **233**: Internal manufacturer sub-designation for pin length or housing material variations. * **R2**: Indicates the physical geometry, specifically a **Right-Angle** orientation (90 degrees). * **Q**: Often denotes **Automotive Quality** (AEC-Q100/200 compliance) or Tape & Reel packaging for automated assembly. --- ### 3. Electrical & Mechanical Characteristics These parts are designed to operate in the harsh environments of a vehicle engine bay or cabin. * **Frequency Range:** DC to 6 GHz (optimized for 0-4 GHz). * **Durability:** Minimum 25 mating cycles. * **Engagement Force:** $\le$ 25 N. * **Temperature Range:** -40°C to +105°C. * **Vibration Resistance:** High resistance to mechanical shock (compliant with USCAR-17). --- ### 4. Common Applications Due to the **"Code A" (Black)** keying, this part is predominantly used for: 1. **AM/FM Radio:** Connecting the antenna to the head unit. 2. **Infotainment Systems:** Signal routing between amplifiers and displays. 3. **Sensor Data:** Low-frequency analog or digital signal transmission where physical locking is required to prevent disconnection due to vibration.
