The OH49E linear Hall circuit consists of a voltage regulator,a Hall voltage generator,a linear amplifier and an emitter follower.The input is magnetic induction and the output is proportional to the input.The quiescent output voltage (B = 0 GS) is half the supply voltage.When the S magnetic pole appears on the Hall sensor marking surface,the drive output is above zero level;the N magnetic pole will drive the output below zero level;the instantaneous and proportional output voltage levels determine the magnetic flux density of the most sensitive surface of the device.Increasing the supply voltage increases sensitivity.<br> Size:1.3x0.4cm/0.51x0.16inch<br> <br> Note:<br> Please allow 1-3mm error due to manual measurement.pls make sure you do not mind before you bid.<br> Due to the difference between different monitors,the picture may not reflect the actual color of the item.Thank you!<br> <br> Package Includes:<br> 10x OH49E Hall Effect Sensor<br> Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures.
