This contactless system measures the absolute angle of a diametric magnetized on-axis magnet. The project is designed for contactless potentiometer applications and its robust design eliminates the influence of any homogenous external stray magnetic fields.  The industry-standard I²C interface supports simple user programming of non-volatile parameters without requiring a dedicated programmer. By default, the output represents a range from 0 to 360 degrees.  It is also possible to define a smaller range to the output by programming a zero angle (start position) and a maximum angle (stop position). The AS5600 is also equipped with a smart low-power mode feature to automatically reduce power consumption. An input pin (DIR) selects the polarity of the output with regard to rotation direction. If DIR is connected to the ground, the output value increases with clockwise rotation. If DIR is connected to VDD, the output value increases with counterclockwise rotation.\u003c\/p\u003e","brand":"dotfry","offers":[{"title":"Default Title","offer_id":46319516680364,"sku":null,"price":600.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0757\/6436\/7532\/files\/contactlesspot_1.jpg?v=1780055324"},{"product_id":"digital-pressure-gauge-0-to-10kpa-0-to-1-75-psi-with-oled-display","title":"Digital Pressure Gauge 0 to 10kPa (0 to 1.75 psi) with OLED display","description":"\u003cp\u003eThe project presented here is a Digital Pressure Gauge using an OLED display.
