Instructions:
A1492:
- Power Supply: Connect Vcc to a stable power supply between 4.5V and 24V.
- Ground Connection: Ensure a solid ground connection to the GND pin.
- Output Signal: The output is a linear analog signal proportional to the magnetic field strength. Use this signal with appropriate signal conditioning circuits.
- Magnetic Field Sensing: Place the sensor in the desired location to detect the magnetic field. The sensitivity is approximately 1.3mV/Gauss.
- Temperature Considerations: Operate within the temperature range of -40°C to 150°C to ensure reliable performance.
C3856:
- Power Supply: Connect the collector (C) to the positive supply voltage, typically up to 20V.
- Emitter Connection: Connect the emitter (E) to ground.
- Base Control: Apply a control signal to the base (B) to modulate the current flow from the collector to the emitter.
- Current Handling: The transistor can handle a maximum collector-emitter current of 100mA.
- Temperature Considerations: Operate within the temperature range of -55°C to 150°C to ensure reliable performance.
- Mounting: Use through-hole mounting for secure installation. Ensure proper heat dissipation if high currents are expected.
