When the supplied slotted encoder wheel rotates through the sensor gap, its solid sections block the infrared beam while its openings allow the beam to pass. These repeated interruptions generate digital pulses that can be counted by a microcontroller.\u003c\/p\u003e\n\u003cp\u003eThe sensor provides a slot width of approximately \u003cstrong\u003e10mm\u003c\/strong\u003e, allowing the included encoder wheel or another suitable interrupting object to pass through the sensing area. It is commonly used with Arduino, ESP32, ESP8266, STM32, Raspberry Pi GPIO and other digital-control platforms.\u003c\/p\u003e\n\u003cp\u003eAn onboard comparator circuit converts the optical signal into a clean digital output. The module commonly includes an adjustable potentiometer for setting the switching sensitivity and an indicator LED for displaying the output state.\u003c\/p\u003e\n\u003cp\u003eBy counting the number of output pulses over a measured time, the controller can determine rotation count, relative speed or RPM. The calculated result depends on the number of slots in the encoder wheel and the number of pulses detected during each revolution.\u003c\/p\u003e\n\u003ch3\u003eCommon Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDC motor speed measurement\u003c\/li\u003e\n\u003cli\u003eMotor RPM detection\u003c\/li\u003e\n\u003cli\u003eWheel rotation counting\u003c\/li\u003e\n\u003cli\u003eOptical encoder projects\u003c\/li\u003e\n\u003cli\u003eObject counting systems\u003c\/li\u003e\n\u003cli\u003eProduction-line counters\u003c\/li\u003e\n\u003cli\u003eRobot wheel-speed sensing\u003c\/li\u003e\n\u003cli\u003eTachometer projects\u003c\/li\u003e\n\u003cli\u003eRotation-position monitoring\u003c\/li\u003e\n\u003cli\u003ePulse-generation experiments\u003c\/li\u003e\n\u003cli\u003eConveyor counting systems\u003c\/li\u003e\n\u003cli\u003eArduino speed-monitoring projects\u003c\/li\u003e\n\u003cli\u003eEducational electronics experiments\u003c\/li\u003e\n\u003cli\u003eSmart automation projects\u003c\/li\u003e\n\u003cli\u003eDIY digital counters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003ePackage Contents:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e1 × 10mm infrared slot photoelectric sensor module\u003c\/li\u003e\n\u003cli\u003e1 × Slotted encoder wheel\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MAJESTRONICZ","offers":[{"title":"Default Title","offer_id":48091494187166,"sku":null,"price":43.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0661\/9257\/2574\/files\/download_55.avif?v=1786025142","url":"https:\/\/majestronicz.in\/products\/10mm-infrared-slot-photoelectric-count-sensor-module-with-encoder-wheel-speed-rpm-and-pulse-detection-sensor-for-arduino","provider":"MAJESTRONICZ","version":"1.0","type":"link"}
