Description
:
The W138 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.
Features
- Wide operating range 3.0~12V, -40℃~125℃.
- Flat Response to 23kHz.
- High Sensitivity 9.0 mV/G.
- Wide sensible magnetic field range on different supplied voltage
±200 Gauss on 5V supplied voltage ±500 Gauss on 12V supplied voltage. Low operating current 3mA.
- Two package styles TO-92S/SOT-23 available.
- Built-in temperature compensated circuit to minimize temperature’s effect
Functional.
