{"product_id":"sparkfun-mikroe-index-counter-click","title":"SparkFun MIKROE Index Counter Click","description":"\u003cp\u003eIndex Counter Click is a simple prototyping high precision Hall-Effect switch solution with direction detection. This board is hosting TLE4966K an integrated circuit dual Hall-effect sensor from Infineon. The sensor is designed specifically for highly accurate applications which use a rotating pole wheel since offers high sensitivity and high stability of the magnetic switching points. Since this sensor is based on two hall probes that provide information about direction and speed of the moving wheel, this makes this product excellent choice for applications such as index counting, rotational speed and direction applications, motor driven position systems.\u003c\/p\u003e \u003cp\u003eIndex Counter Click is supported by a mikroSDK compliant library, which includes functions that simplify software development.\u003c\/p\u003e \u003cp\u003eThe Index Counter Click is based around the TLE4966K, which is a high sensitivity and high stability of the magnetic switching points sensor with reverse battery protection (-18 V). This sensor has many features that make it a perfect solution for small designs such as the Index Counter Click board�. One of these features is certainly its high level of integration that allows a minimal number of external components.\u003c\/p\u003e \u003cp\u003eThe TLE4966K provides excellent temperature compensation capability for keeping the output stable under changing temperature. It is designed specifically for highly accurate applications with a speed signal for every magnetic pole pair, as well as direction information. The TLE4966 Hall Sensors feature two integrated and calibrated sensor elements for detecting direction and counting indexes. This feature eliminates the need for a second sensor and cuts engineering and production costs. Using just one sensor also raises system quality and reliability.\u003c\/p\u003e \u003cp\u003eThe chopped Double Hall Switch comprises two Hall probes, bias generator, compensation circuits, oscillator, and output transistors.\u003c\/p\u003e \u003cp\u003eThe bias generator provides currents for the Hall probes and the active circuits. Compensation circuits stabilize the temperature behavior and reduce technology variations.\u003c\/p\u003e \u003cp\u003eThe Active Error Compensation rejects offsets in signal stages and the influence of mechanical stress to the Hall probes caused by molding and soldering processes and other thermal stresses in the package. This chopper technique together with the threshold generator and the comparator ensures high accurate magnetic switching points.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eInterface: GPIO\u003c\/li\u003e \u003cli\u003eCompatibility: mikroBUS�\u003c\/li\u003e \u003cli\u003eDimensions: 28.6 x 25.4mm\u003c\/li\u003e \u003cli\u003eInput Voltage: 3.3V or 5V\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eDocuments:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/3\/c\/e\/9\/1\/Schematic-19500-MIKROE_Index_Counter_Click.pdf\"\u003eSchematic\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/4\/4\/0\/b\/7\/TLE4966K-DS-v01_00-en.pdf\"\u003eTLE4966K-DS Datasheet\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/www.mikroe.com\/mikrosdk\"\u003emikroSDK\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/github.com\/MikroElektronika\/mikrosdk_click_v2\/tree\/master\/clicks\/indexcounter\"\u003eGitHub\u003c\/a\u003e\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eVideos\u003c\/strong\u003e\u003c\/p\u003e \u003cdiv class=\"flex-video-wrap clearfix\"\u003e \u003cdiv class=\"flex-video widescreen img\"\u003e \u003ciframe src=\"https:\/\/www.youtube.com\/embed\/zzlh1oGii1Q\/?autohide=1\u0026amp;border=0\u0026amp;wmode=opaque\u0026amp;enablejsapi=1\" frameborder=\"0\" allowfullscreen width=\"560\" height=\"315\"\u003e\u003c\/iframe\u003e \u003c\/div\u003e \u003c\/div\u003e","brand":"sparkfun-10","offers":[{"title":"Default Title","offer_id":40054698934357,"sku":"19500:SEN-19500:spark","price":1175.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1034\/1611\/products\/19500_-_MIKROE_Index_Counter_Click_2.jpg?v=1651343714","url":"https:\/\/www.tanotis.com\/products\/sparkfun-mikroe-index-counter-click","provider":"Tanotis","version":"1.0","type":"link"}
