SL1709SU Hall Effect Sensor TO-92S
SL1709SU is a high-performance, ultra-low-power, omnipolar Hall-effect switch sensor designed for battery-powered and compact systems. It detects both N‑pole and S‑pole magnetic fields with ultra‑low threshold, using internal sleep‑wake logic and temperature compensation to achieve stable magnetic detection with minimal power consumption. It features CMOS push‑pull output and adopts TO‑92S through‑hole package, making it ideal for manual soldering, testing, and low‑power industrial applications.
