The Speed & Direction Hall effect sensor has two distinct Hall sensing elements precisely located 1.4 mm apart on a single integrated circuit chip, which is then encapsulated in a thermoset molding material. Two active Hall latches provide indication of the speed and direction of a magnetic gradient across the face of the package, such as the gradient from a rotating ring magnet. The small, 4-pin SOT89 style package surface mounts on PC boards and flexible circuits. Built-in temperature compensation is optimized to match the temperature coefficient of low cost magnets and track their performance over temperature. Latching magnetics are standard for reliable operation. A unique regulator circuit provides extremely stable operation with supply voltages as low as 3.4 Vdc and as high as 24 Vdc. A typical room temperature current consumption of 7.5 mA helps conserve power in battery operation. SS520 series sensors can use existing power supply sources in most applications, and can be directly interfaced with many electronic components without buffering or compensation circuitry. CAUTION: WAVE SOLDER DAMAGE do not wave solder this product. Wave soldering may negatively affect the sensor performance and reliability. Subjecting the sensor to wave soldering will void Honeywell's warranty. Failure to comply with these instructions may result in product damage. NOTE: Interruption of power to a latching device may cause the output to change state when power is restored. If a magnetic field of sufficient strength is present, the sensor output will be in the condition dictated by the magnetic field.
