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.
