Reading system of alternating light transmitting window and the window is not consisting of radial indexing plate (code wheel) rotating basis, while being an infrared light source vertical irradiation light to the code disk image onto the receiving on the surface. Receiver is covered with a diffraction grating, which has the same code disk window width. The receiver's job is to feel the rotation of the disc resulting changes, and change the light into corresponding electrical changes. Then the low-level signals up to a higher level, and generates no interference square pulse, which must be processed by electronic circuits. Reading systems typically employ a differential manner, about the same but the phase difference of the two waveforms different by 180¡ãcompared to the signal in order to improve the quality and stability of the output signal. Reading is then the difference between the two signals formed on the basis,thus eliminating the interference.\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eWorking Voltage: 5V\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003ePacking List:\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e1 x KY-040 Rotary Encoder Module\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"HALJIA","offers":[{"title":"Default Title","offer_id":42184382218486,"sku":"420429420429","price":3.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0550\/2523\/8262\/products\/1_a140192d-052c-49f4-af61-154f10c66211.jpg?v=1638340695"},{"product_id":"haljia-portable-electronic-weight-sensor-load-cell-weighing-sensor-1kg-compatible-with-arduino-raspberry-pi-diy-etc","title":"HALJIA Portable Electronic Weight Sensor Load Cell Weighing Sensor (1KG) Compatible with Arduino Raspberry Pi DIY Etc","description":"\u003cul class=\"a-unordered-list a-vertical a-spacing-mini\" data-mce-fragment=\"1\"\u003e\n\u003cli data-mce-fragment=\"1\"\u003e\u003cspan class=\"a-list-item\" data-mce-fragment=\"1\"\u003ePortable electronic weight sensor\u003c\/span\u003e\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e\u003cspan class=\"a-list-item\" data-mce-fragment=\"1\"\u003eRated load: 1Kg\u003c\/span\u003e\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e\u003cspan class=\"a-list-item\" data-mce-fragment=\"1\"\u003eFor DIY Arduino etc.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e\u003cspan class=\"a-list-item\" data-mce-fragment=\"1\"\u003eRecommended operating voltage: 3 ~ 12 V DC\u003c\/span\u003e\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e\u003cspan class=\"a-list-item\" data-mce-fragment=\"1\"\u003eProtection class: IP65\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan class=\"a-list-item\" data-mce-fragment=\"1\"\u003e\u003cspan class=\"a-text-bold\"\u003eSpecification:\u003cspan\u003e \u003c\/span\u003e\u003c\/span\u003e\u003cspan\u003e\u003cbr\u003eRated load: 1kg \u003cbr\u003eRated output: 1.0mV \/ V + -0.15mV \/ V \u003cbr\u003eZero output: ± 0.1mV \/ V \u003cbr\u003eCreep: 0.03% F.S.\/30min\u003cbr\u003eInput end: red + , black- \u003cbr\u003eOutput end: green + , white- \u003cbr\u003eRecommended operating voltage: 3 ~ 12 V DC\u003cbr\u003eMaximum operating voltage: 15 V DC\u003cbr\u003eInput impedance: 1115 ± 10% R \u003cbr\u003eOutput impedance: 1000 ± 10% R \u003cbr\u003eProtection class: IP65 \u003cbr\u003eOverall size approx. 8 x 1.3 x 1.3 cm \u003cbr\u003eCable size: 0.8 x 20 cm (diameter x length) \u003cbr\u003eMaterial: aluminum alloy \u003cbr\u003e\u003cbr\u003e\u003c\/span\u003e\u003cspan class=\"a-text-bold\"\u003ePackage Inculded:\u003cspan\u003e \u003c\/span\u003e\u003c\/span\u003e\u003cspan\u003e\u003cbr\u003e1 x weighing sensor (cable: 20 cm) \u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"HALJIA","offers":[{"title":"Default Title","offer_id":42184430485750,"sku":"422361422361A","price":5.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0550\/2523\/8262\/products\/1_6734cf5e-1bfb-4a7c-bc9f-3b1023a34d3c.jpg?v=1638348112"},{"product_id":"haljia-diy-50kg-body-load-cell-weighing-sensor-resistance-strain-half-bridge-original-compatible-with-diy-arduino-etc","title":"HALJIA DIY 50Kg Body Load Cell Weighing Sensor Resistance strain Half-bridge Original Compatible with DIY Arduino Etc","description":"\u003cul class=\"a-unordered-list a-vertical a-spacing-mini\" data-mce-fragment=\"1\"\u003e\n\u003cli data-mce-fragment=\"1\"\u003e\u003cspan class=\"a-list-item\" data-mce-fragment=\"1\"\u003eThe internal 1000 ohm half bridge strain gauge, the measuring range is 50kg weighing sensor, half bridge structure.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e\u003cspan class=\"a-list-item\" data-mce-fragment=\"1\"\u003eFor DIY Arduino Etc\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan class=\"a-list-item\" data-mce-fragment=\"1\"\u003e\u003cspan\u003eThe internal 1000 ohm half bridge strain gauge, the measuring range is 50kg weighing sensor, half bridge structure.\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eSize: 34mm x 34mm\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eThis sensor is a group of half bridge strain gauge, using the method can have the following three:\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e1, using a sensor with the external resistance to form a full bridge measurement, the range of a sensor range: 50kg.
