Technical Specifications Overview The following table highlights the core electronic characteristics of this series: | Parameter | Specification (Typical) | | :--- | :--- | | **Input Voltage (Vcc)** | 5V DC (±10%) | | **Output Type** | Analog (Ratiometric) / PWM / Digital | | **Resolution** | 10-bit to 12-bit (depending on configuration) | | **Operating Temperature** | -40°C to +125°C (Automotive Grade) | | **Interface** | 3-wire or 4-wire interface | | **Mounting Style** | Surface Mount (SMD) or Module-based | --- ### 2. Functional Electronic Components The device operates using **Hall Effect** technology. Below is a breakdown of the internal logic: #### A. Sensing Element * **Integrated Hall Array:** This part detects the orientation of a magnetic field from a small permanent magnet placed above the chip. * **Contactless Operation:** Since there is no physical contact between the sensor and the rotating part, there is zero mechanical wear. #### B. Signal Processing (ASIC) * **ADC (Analog to Digital Converter):** Converts the raw sine/cosine signals from the Hall sensors into a digital value. * **CORDIC Processor:** A specialized logic block that calculates the exact angle ($\theta$) based on the magnetic field vectors. #### C. Output Stage * **Operational Amplifier (Op-Amp):** Buffers the output signal to ensure it can drive the input of an external Microcontroller (MCU) or Engine Control Unit (ECU). * **Protection Circuitry:** Includes Reverse Polarity Protection and Overvoltage Protection to survive harsh electrical environments. --- ### 3. Pinout and Connectivity While pinouts can vary slightly based on the specific housing (R2/Q variant), the standard configuration follows this logic: 1. **VCC:** Power Supply (Positive). 2. **GND:** Ground. 3. **OUT:** The analog or PWM signal representing the absolute position (0° to 360°). 4. **TEST/CAL:** Used by the manufacturer for end-of-line calibration. --- ### 4. Common Applications * **Throttle Position Sensors (TPS):** Monitoring the angle of the butterfly valve in engines. * **Steering Angle Sensors:** Providing feedback for electronic stability control. * **Pedal Sensors:** Detecting the position of accelerator or brake pedals. * **Actuators:** Closed-loop control in industrial robotics.
