WSH135
Winson reserves the right to make changes to improve reliability or manufacturability.
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.
