NSM1011 Unipolar Hall Switch
NSM1011 is 3-wire fixed sensitivity Hall switch, which is automotive-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 150°C.It meets the requirements of AEC-Q100 and are developed according to the ISO 26262:2011 standard and its functional safety level meets up to ASIL A.
The NSM101X series consists of 3 product models, namely NSM1011 (unipolar Hall switch), NSM1012 (omnipolar Hall switch), and NSM1013 (Hall latch), which allow users to select different switching points, magnetic polarity, output polarity, normal power consumption and low power consumption modes, temperature compensation coefficients of magnet materials, package forms, etc.
