Functional Description
The WSH135 integrates Hall sensing element, linear amplifier, sensitivity controller and emitter follower output stage. It accurately tracks extremely small change in magnetic flux density which is generally too small to operate Hall effect switch.
WSH135 can be applied as current sensor, tooth sensor, proximity...
