LinkMejor 2 Pcs 3144 Hall Effect Sensor Magnetic Detector 4.5-24V

These Hall-effect switches are monolithic integrated circuits with tighter magnetic specifications, designed to operate continuously over extended temperatures to +150C, and are more stable with both temperature and supply voltage changes. The unipolar switching characteristic makes these devices for use with a simple bar or rod magnet. The four basic devices (3141, 3142, 3143, and 3144) are identical except for magnetic switch points.
