Product Overview
The SL170x Series is a low-power, high-performance Hall-effect switch sensor designed for compact and battery-sensitive systems. It offers omnipolar magnetic field detection, a wide operating voltage range (1.8V to 5.5V), and multiple magnetic field thresholds (26Gs, 36Gs, 48Gs) to suit various applications. Available in SOT-23-3L, TO-92S, and HFBP1010-4L packages, these sensors provide stable operation with built-in temperature compensation and clock logic. Typical applications include laptop and tablet switch detection, TWS earbuds, mobile phones, electronic locks, valve position sensing, water/gas meters, and non-contact detection.
