WSH49E Linear Hall Effect Sensor 49E Hall Element

The AH49E integrates Hall sensing element, linear amplifier, sensitivity controller, an emitter follower output stage. It accurately tracks the extremely small change in magnetic flux density generally too small to operate Hall-effect switch. WSH49E can be applied as a current sensor, tooth sensor, proximity detector, and motion detector. As a sensitive monitor of magnetic flux, it can effectively measure the performance of a system with negligible system loading while providing isolation from contaminated and electrically noisy environments.
49E is a Linear Hall-Effect sensor with a small size and economical price. Hall effect devices are operated by a magnetic field from an electromagnet or a permanent magnet. The user must set souring output voltage by supply voltage. The output voltage varies in proportion to the strength of the magnetic field.
