Product Description
Product Overview
The SL170x Series is a high-performance, low-power Hall effect switch sensor designed for compact and battery-sensitive systems. It offers versatile magnetic field detection with selectable thresholds (26Gs, 36Gs, 48Gs) and full-polarity sensing. With a wide operating voltage range of 1.8V to 5.5V and low current consumption, it is ideal for applications such as laptop and tablet lid detection, TWS earbuds, mobile phones, electronic locks, valve position sensing, water/gas meters, flow meters, and non-contact detection. The sensor features CMOS push-pull output, excellent ESD performance (HBM 8KV), and is RoHS compliant.
