{"product_id":"pl4-com-09312","title":"Hall-Effect Sensor - US1881 (Latching)","description":"\u003cp\u003eThe US1881 is an integrated Hall-Effect latched sensor. 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.\u003c\/p\u003e  \n\n \u003cp\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.\u003c\/p\u003e  \n\n \u003cp\u003eIf a magnetic flux density 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\/p\u003e\n\n\u003cp\u003e**Features:**\u003c\/p\u003e\n\n\u003cp\u003e* 3.5V to 24V DC operation voltage\u003cbr\u003e\n* Low current consumption\u003cbr\u003e\n* Temperature compensation\u003cbr\u003e\n* Wide operating voltage range\u003cbr\u003e\n* Open-Collector pre-driver\u003cbr\u003e\n* 50mA maximum sinking output current\u003cbr\u003e\n* Reverse polarity protection\u003cbr\u003e\n* Lead Free Package: TO-92\u003c\/p\u003e\n\n\u003cp\u003e**Documents:**\u003c\/p\u003e\n\n\u003cp\u003e* [Datasheet](http:\/\/www.sparkfun.com\/datasheets\/Components\/General\/Hall-US1881EUA.pdf)\u003c\/p\u003e\n\n\u003cp\u003e**Videos**\u003c\/p\u003e","brand":"PuriLite","offers":[{"title":"Default Title","offer_id":39705316950197,"sku":"PL4-COM-09312","price":8.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0526\/9553\/1701\/products\/09312-1.jpg?v=1618236895","url":"https:\/\/getcahits.com\/products\/pl4-com-09312","provider":"PuriLite","version":"1.0","type":"link"}
