TDK Corporation Sensors, Transducers - Magnetic Sensors - Switches (Solid State) HAL581 SF-E

The HAL581 is a two-wire unipolar inverted Hall-effect sensor that switches to low current consumption when a magnetic south pole is applied to the branded side and to high current consumption when the magnetic field is removed. It operates with static and dynamic magnetic fields up to 10 kHz and is available in the SOT89B-1 package. The sensor has an on-point magnetic flux density ranging from 6.5 mT to 14.3 mT and an off-point ranging from 8 mT to 16 mT across its junction temperature range of −40°C to +140°C, with typical hysteresis of 0.5 mT to 3.5 mT. Its supply voltage range is 3.75 V to 24 V. The device is not designed for use in life-supporting or safety-critical systems.
