Functional Description :
The W137 integrates Hall sensing element, linear amplifer, sensitivity
controller and emitter follower output stage.It accurately tracks extremely small
change in magnetic flux density –generally too small to operate Hall effect
switch.
W137 can be applied as current sensor, tooth sensor, proximity detectors
and motion detectors. As sensitive monitor of magnetic flux, it can effectively
measure a system’s performance with negligible system loading while
providing isolation from contaminated and electrically noisy environments.
Winson reserves the right to make changes to improve reliability or manufacturability.
