Description
SS495 Linear Hall-effect sensor is a small, ver- satile linear Hall -effect device that is operated by the magnetic field from a permanent magnet or an electromagnet. The linear sourcing output voltage is set by the supply voltage and varies in proportion to the strength of the ma gnetic field. Specifically, when S495 is in the zero magnetic field conditions, the output voltage is half of the supply voltage. When south poles approach the S495 marking surface, the output voltage will increase linearly with the magnetic field strength; on the other hand, north pole will cause output voltage decreases linearly with the increase in magnetic field strength. The int e- grated circuitry features low noise output, which makes it unnecessary to use external filtering. It also includes thin film resistors to provide i n- creased temperature stability and accuracy. The linear Hall sensor has an operating temperature range of -40 °C to 150 °C appropriate for co m- mercial, consumer and industrial environments. Typical Applications ─ Electric vehicles speed regulation pedal ─ Motion detector ─ Gear sensing ─ Motor control ─ Magnetic code reading ─ Ferrous metal detector ─ Current sensing ─ Position sensing ─ Proximity detector Functional Block Diagram

Should be installed by minimizing the mechanical stress on the Hall circuit; 2. On the conditions of ensuring the quality of the welding, the welding temperature and time should be reduced as far as possible.
