You know us as a leader， whether you’ve known us as MICRO SWITCH or Honeywell Sensing and Internet of Things （SIoT）。 In 1968， we revolutionized the industry with the first solidstate keyboard combining Hall-effect sensing and associated electronics in a single circuit. Today， the Honeywell SIoT family of magnetic position sensors includes digital and analog Hall-effect position， magnetoresistive digital， Hall-effect vane， gear-tooth， and Hall-effect basic switches and magnets. These high-speed， extended life sensors are often directly compatible with other electronic circuits， responding to the presence or the interruption of a magnetic field by producing a proportional output. Gear-tooth and other packaged Hall-effect speed and direction sensors sense movements of a ferrous metal target. Digital and analog “sensor-only” devices are operated by a permanent magnet or electromagnet， while actuation mode depends on the type of magnets used. A vane passing through a gap or a magnet mounted on a plastic plunger operates integral magnet position sensors. "SS361RT磁傳感器線導"
