High sensitivity Hall HAL581 straight hair curlers non-contact switch

 Define unipolar Hall switch: Hall switch is divided: Unipolar Hall switch bipolar Hall switch, polarity Hall switch (or full polarity Hall switch), where polarity means The polarity of the N pole magnet (Arctic) or S (south) pole, then unipolar Hall switch means switches [Hall Microelectronics] specifies the positive and negative polarity of a magnetic field near the left will have a switching effect. Generally Unipolar Hall switch front (literally) specifies the effective magnetic pole S, N Hall switch near the opposite pole effective HAL58 high sensitivity Hall switch sensor SOT-23 Package TO-92UA line temperature sensor HAL58 Hall Unipolar Hall switch provided by the Hall of microelectronics. HAL58 Unipolar Hall Switch is a technology-based mixed-signal COMS unipolar Hall-effect sensor IC. This IC adopts advanced chopper stabilization technology, which can provide accurate and stable magnetic switching points. In addition to applications listed in the table below, the Fengyun Hall element, there are many applications. But its design, specifications and performance point of view, HAL58 unipolar Hall switch is particularly suitable for solid state switches. HAL58 Hall switch operating voltage: 2.5V-24V Working temperature: -65-150 degrees [Hall Microelectronics] Unipolar Hall element HAL58 Features [Hall Microelectronics] chopper amplifier built without contact. switch position control. High reliability of ultra-small, ultra-thin new package. speed detection. isolation testing. Working voltages as low as 3.5V. DC brushless motor current sensor. CMOS process to achieve high stability, high-quality pole Hall switch element HAL58 Typical applications pass auto ignition safety alarm device is particularly suitable for a brushless DC motor applications [Hall Microelectronics] High sensitivity, can replace reed applications based on sensitivity to low HAL58 classified as HAL581 HAL582 HAL583 [Hall Microelectronics] suggests: all plant protection equipment are grounded, the operator with electrostatic rings
