TDK HAL188x Programmable Linear Hall-Effect Sensors
TDK HAL188x Programmable Linear Hall-Effect Sensors are designed with a ratiometric and linear analog output proportional to the magnetic flux density applied to the sensor surface. The robust and cost-effective design makes the sensor ideal for small-angle or linear position measurements, gear position detection, rotary selectors, and current sensing for battery management. TDK HAL188x Programmable Linear Hall-Effect Sensors are AEC-Q100 qualified and operate in the junction temperature ranging from -40°C to +170°C. These sensors are available in a very small leaded TO92UA-2 package.
