20pcs OH137 OH 137 Linear Hall Effect Magnetic Unipolar Sensor Switch IC Arduino

Description:Hall-effect sensors are commonly used for measuring the speed of rotating assemblies where a magnet on the assembly alternately makes and breaks magnetic contact with the sensor as the assembly rotates. They can also be used for applications such as determining when a door has been opened, position sensing and detecting the magnetic field created by current flow in a wire.Features4.5V to 24V DC operation voltageOpen-Collector pre-driver25mA maximum sinking output current.Reverse Polarity ProtectionApplications Speed measurementHome appliancesPosition detectionFlow measurementAbsolute Maximum Ratings （TA=25℃）Supply Voltage VCC··············4.5-24VOperating Temperature Range TA ···········-40～85℃Output Current IO···················25mAStorage Temperature Range TS ················-55～150℃Package included:20pcs OH137 OH 137 Linear Hall Effect Magnetic Unipolar Sensor Switch IC for Arduino
