That’s nice but what does it do? Holding a magnet near the sensor will cause the output pin to toggle. This makes for a robust presence sensor. A reed sensor also works nicely, but can be limited by the glass encapsulation and size. A hall effect sensor is much smaller, but can handle less current than a reed switch.\u003cbr\u003e\u003cbr\u003eThe device includes an on-chip Hall voltage generator for magnetic sensing, a comparator that amplifies the Hall voltage, and a Schmitt trigger to provide switching hysteresis for noise rejection, and open-collector output. An internal bandgap regulator is used to provide temperature compensated supply voltage for internal circuits and allows a wide operating supply range.\u003cbr\u003e\u003cbr\u003eIf a magnetic flux density is larger than threshold Bop, DO is turned on (low). The output state is held until a magnetic flux density reversal falls below Brp causing DO to be turned off (high).\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eTechnical Details\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eOperating Voltage: 3.5V – 24V DC\u003c\/li\u003e\n\u003cli\u003eCurrent Consumption: Low power usage\u003c\/li\u003e\n\u003cli\u003eOutput Type: Open-collector\u003c\/li\u003e\n\u003cli\u003eMaximum Sinking Output Current: 50mA\u003c\/li\u003e\n\u003cli\u003eResponse Time: Fast switching\u003c\/li\u003e\n\u003cli\u003eTemperature Compensation: Built-in for stability\u003c\/li\u003e\n\u003cli\u003eReverse Polarity Protection: Yes\u003c\/li\u003e\n\u003cli\u003ePackage Type: TO-92\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eFeatures\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003e3.5V – 24V DC operation\u003c\/li\u003e\n\u003cli\u003eLow power consumption\u003c\/li\u003e\n\u003cli\u003eTemperature compensated\u003c\/li\u003e\n\u003cli\u003eWide voltage range\u003c\/li\u003e\n\u003cli\u003eOpen-collector pre-driver\u003c\/li\u003e\n\u003cli\u003e50mA max sinking output\u003c\/li\u003e\n\u003cli\u003eReverse polarity protection\u003c\/li\u003e\n\u003cli\u003eLead-free TO-92 package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch2 class=\"sing--sub-heading\"\u003e\u003cspan style=\"font-size: 18.72px;\"\u003eApplications :\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProximity sensing\u003c\/strong\u003e – Detects nearby magnetic fields\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpeed measurement\u003c\/strong\u003e – Used in motor and fan speed monitoring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePosition detection\u003c\/strong\u003e – Determines the position of rotating objects\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent sensing\u003c\/strong\u003e – Measures electrical current in circuits\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecurity systems\u003c\/strong\u003e – Magnetic door and window sensors\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003ePhysical Attributes\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eDimension: 21.7mm x 8.7mm\u003c\/li\u003e\n\u003cli\u003eWeight: 1 g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003ePackage Includes\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds ls-n\"\u003e\n\u003cli\u003e1 x A3144 Hall Effect Sensor\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"KitsGuru","offers":[{"title":"Default Title","offer_id":44663584260348,"sku":"KG1070","price":9.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/files\/AH3144EHallSensor-2.jpg?v=1741608038","url":"https:\/\/kitsguru.com\/es\/products\/ah3144e-hall-sensor","provider":"KitsGuru","version":"1.0","type":"link"}
