Description
SL1709SL is a high-performance, ultra-low-power, omnipolar Hall-effect switch designed for battery-powered and space-constrained applications. It detects both N and S magnetic poles with stable sensitivity, using internal sleep-wake control and temperature compensation to maintain reliable operation with minimal power consumption. It features CMOS push-pull output and comes in a TO-92S through-hole package, ideal for manual assembly, testing, and industrial control.
Our Advantages
