NSM1071 Unipolar Hall Switch
NSM1071 is a 3-wire fixed sensitivity Hall switch, which are industrial-grade magnetic sensors based on the planar Hall-effect to support high-precision, contactless digital position measurement within an ambient temperature range of -40°C to 125°C.
The low power version of the NSM1071 with 20Hz sampling frequency has an operating current as low as 1.5μA at the common supply voltage of 3.3V, making it suitable for battery-powered applications such as IOT devices.
The NSM107X series consists of 2 product models, namely NSM1071 (unipolar Hall switch) and NSM1072 (omnipolar Hall switch), which allow users to select different switching points, power consumption modes, output interfaces, package forms, etc.
