41F Linear Hall Effect Sensor for E-bike Throttle Grip, Speed Sensor, Accelerator Sensor

Description

The 41F contains a Hall-effect voltage generator, voltage regulator, dynamic offset cancellation, temperature compensation circuitry, Schmitt trigger, and an open-collector sinking output stage.

• How it works: Because it is a latching sensor, it turns ON (low output voltage) when exposed to a strong South magnetic pole. The output remains latched low even if the South pole is removed. It only turns OFF (high output voltage) when exposed to an opposing North magnetic pole.Specification
