Description
SL1729SH is a high-performance, ultra-low-power Hall-effect switch that only detects North (N-pole) magnetic fields. It is designed for battery-powered and space‑constrained systems, using internal wake‑sleep control and temperature compensation to ensure stable detection at 25Hz. It features CMOS push‑pull output and comes in a TO‑92S through‑hole package, ideal for easy assembly, testing, and industrial applications.
