Key Highlights *Power Consumption of 3.5mA at VCC = 5V for Energy Efficiency Miniature Construction Single Current Sourcing Output Linear Output for Circuit Design Flexibility Low Noise Output Virtually Eliminates the Need for Filtering A Stable and Accurate Output Temperature Range of -40°C to +85°C Responds to Either Positive or Negative Gauss Discription- A3144 is a small, versatile, linear unipolar hall-effect sensor that acts as a magnetic switch. This hall effect sensor is just like switch but more sensitive to magnetic flux and suitable for harsh environment because of semiconductor type casing and no glass encapsulation. This type of unipolar hall effect sensor changes its state if one pole of magnet comes near it. This is ideal for commercial, consumer and industrial applications.
