Series Description
The temperature compensated Hall effect sensor consists of a quad Hall sensing element in a square integrated circuit chip, which is then encapsulated in a glass-filled thermoset molding material. The small SOT89 style package surface mounts on PC boards and flexible circuits.
The integrated circuit is thermally balanced for predictable performance over specified temperature range. Built-in temperature compensation has a negative slope (operate and release points decrease as temperature increases). This slope is optimized to match the negative temperature coefficient of low cost magnets, to track their performance over temperature. Bipolar, unipolar and latching magnetics are available.
Band gap regulation provides extremely stable operation over the full supply voltage range. SS500 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.
NOTE: Do not wave solder this product. This process may negatively affect sensor performance and reliability, and will void Honeywell's warranty. Honeywell recommends a convection infrared reflow process with peak temperatures not to exceed 250 °C [482 °F] for 3 seconds maximum.
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.
