49E Hall
The 49E is a Linear Hall-Effect sensor that integrates a Hall sensing element, linear amplifier, sensitivity controller, and an emitter-follower output stage. This design enables it to detect even the smallest changes in magnetic flux density, which are often too subtle to trigger typical Hall-effect switches. The WSH49E variant is particularly versatile, with applications as a current sensor, tooth sensor, proximity detector, and motion sensor.
As a highly sensitive monitor of magnetic flux, the 49E measures system performance with minimal load on the system and offers isolation from electrically noisy or contaminated environments. Its compact size and cost-effectiveness make it a popular choice in a variety of applications.
Hall-effect devices like the 49E respond to magnetic fields generated by electromagnets or permanent magnets. By supplying voltage to the sensor, users can adjust the output voltage, which varies proportionally to the strength of the detected magnetic field.
