WSH49E Linear Hall Effect Sensor IC Features: z Wide operating range 3.0~6.5V, -20℃~100℃ z z z Flat Response to 23kHz Low noise output Wide sensible magnetic field range on different supplied voltage ±900 Guass on 5V supplied voltage Small package styles TO-92S available. z Functional Description : The WSH49E 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. WSH49E 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.
