The SC2442SO-N , with SOT-23 Hall Sensor ROHS, is a Hall effect sensor manufactured by Semiment. It is an integrated device that uses a hall-effect element to detect both positional and magnetic field changes. It features a flat lead SOT-23 package, allowing it to be used in space-constrained applications. It provides low power output, with a maximum output current of 300mA and a supply voltage range of 2.7V to 5.5V. Additionally, the device is RoHS compliant, meaning it is free from hazardous substances such as lead. This Hall effect sensor is an excellent choice for low-power sensing applications.
