TA -65 ~ 150 temperature storage temperature | TS 165 ℃ unipolar the definition of Hall switches: Hall switch is divided: Unipolar Hall switch bipolar Hall switch, non-polar Hall switch (or full polarity Hall switch), where the polarity of the magnet means Polarity N pole (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 near the opposite pole switch Hall switch magnetic characteristics and effective definition: B is the magnetic field strength, used to represent the Hall device switches point, the unit is GS (Gaussian), or T (Tesla), the conversion relation is 1GS = 0.1mT. B magnetic field strength of the South Pole and the North Pole of the points, it is necessary to remember its algebraic relations, Arctic magnetic field is negative, the Antarctic magnetic field is positive. This relationship can be compared magnetic North Pole South Pole algebraic relations, the relative strength of the magnetic field is represented by the absolute value of B, [Hall Microelectronics] symbol indicates polarity. For example: a -100GS (Arctic) magnetic field and a 100GS (south) magnetic field strength is the same, but opposite polarity. -100GS Strength than -50GS. ? BOP - field work points; the Hall switch is turned on magnetic field strength. Hall switch output parameter depends on the electrical design of the device. ? BRP - magnetic release point; switch off the Hall [Hall Microelectronics] magnetic field strength. Hall switch output parameter depends on the electrical design of the device. ? BHYS - magnetic switching points hysteresis window. Transfer Function Hall element using the difference between the switching points to filter out smaller value may fluctuate due to mechanical vibration or electromagnetic noise caused by magnetic fields in the application. BHYS = |? BOP BRP |.
