This counting method has no limitation, it can reset and \ncome back to the initial status if matching with the key on the encoder \n(that is to say it will count from 0)\n4.Operating\n Principle: Incremental encoder is a kind of rotary sensor which \ntransforms the rotation displacement into a series of digital pulse \nsignal. These pulses are used to control angular displacement. In Eltra \nencoder, the transformation of angular displacement adopts photoelectric\n scaning principle. The reading system is based on the radial dividing \nplate's rotation of alternative light window and non-light window, and \nit will be exposed to infrared light source at the same time. The light \nwill reflect the picture of plate on the surface of receiver. The \nreceiver is covered by a diffraction grating, and it has the same window\n width with the plate. The operation of receiver is to detect the change\n of light plate rotation, then transform the light change into electric \nchange. Increase the low level signal into high level and generate \nsquare pulse without any interference. This process needs circuit to \ndeal with. The reading system usually adopts differential method, that \nis compare two different signals who have the same waveform bu the phase\n difference is 180 degree so as to improve the output signal quality and\n stability. Reading is formed on the basis of the difference between two\n signals, so it eliminates the interference\u003c\/span\u003e\u003cimg src=\"https:\/\/static-01.daraz.pk\/p\/02bbacd55841625393089ad0ce65c7e8.jpg\" style=\"width:721px;height:721px;display:inline;vertical-align:middle\"\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"line-height:1.7;text-align:left;text-indent:0;margin-left:0;margin-top:0;margin-bottom:0\"\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e\u003c\/article\u003e","brand":"Store","offers":[{"title":"Blue","offer_id":47939573711011,"sku":"410427720_PK-1963253585","price":450.0,"currency_code":"PKR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0730\/7467\/1779\/files\/cc441676017e43f9e3869a37591bcc22_2faaa1bf-610c-4b6c-9493-8b96f56f2f07.jpg?v=1785450314","url":"https:\/\/www.aonepak.com\/products\/410427720-410427720_pk-1963253585","provider":"A One World Super Store","version":"1.0","type":"link"}
