| WSH135 Features: Wide operating range 3.0~12V, -20 ~8 Flat Response to 23kHz Low noise output Wide sensible magnetic field range on different supplied voltage 1,500 Guass on 5V supplied voltage 4,500 Guass on 12V supplied voltage. Low operating current 3mA Two package styles TO-92S/SOT-23 available. Functional Description : The WSH135 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. WSH135 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.
