WSH138 Datasheet Linear Hall Effect Sensor

Manufacturer: Winson

Overview: WSH138 Linear Hall Effect Sensor IC.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General 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.

W138 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.

Key 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.
