Instructions

A1941 Hall Effect Sensor

1. Power Supply: Connect the Vcc pin to a power supply between 4.5V and 24V.
2. Ground: Connect the GND pin to the ground of your circuit.
3. Output: The output pin will be open collector, so you need to connect a pull-up resistor between the output and Vcc.
4. Mounting: Ensure the sensor is mounted in a location where it can detect the magnetic field without interference.
5. Operation: When a magnetic field is detected, the output will go low (0V). Otherwise, it will remain high (Vcc).

C5198 Diode

1. Forward Connection: Connect the anode (positive) to the higher potential and the cathode (negative) to the lower potential.
2. Reverse Protection: Ensure the reverse voltage does not exceed 100V to prevent damage.
3. Current Limiting: Do not exceed the maximum forward current of 0.5A.
4. Heat Dissipation: The diode can dissipate up to 0.3W of power. Use appropriate heat sinking if operating at high currents or in high-temperature environments.
5. Mounting: Ensure the diode is securely mounted to avoid mechanical stress on the leads.
