{"product_id":"moc7811-opto-sensor","title":"MOC7811 OPTO SENSOR","description":"\u003cp\u003eThe MOC7811 Slotted Opto-Isolator is a slotted optical sensor with an IR LED emitter and phototransistor receiver facing each other across a 3mm-wide, 7mm-deep slot. When an object passes through the slot it interrupts the IR beam, changing the phototransistor output state. Used for rotary encoder position sensing, motor speed measurement, and object detection.\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eSlot Width: 3mm\u003c\/li\u003e\n\u003cli\u003eSlot Depth: 7mm\u003c\/li\u003e\n\u003cli\u003eMounting Hole Spacing: 19mm\u003c\/li\u003e\n\u003cli\u003eMounting Hole Diameter: 3mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003eConnections:\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eIR LED: Anode — VCC (with series resistor), Cathode — GND\u003c\/li\u003e\n\u003cli\u003ePhototransistor: Collector — VCC (with pull-up), Emitter — GND; output taken at Collector\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003eApplications:\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eMotor shaft encoder (speed\/position feedback)\u003c\/li\u003e\n\u003cli\u003eFactory automation robots\u003c\/li\u003e\n\u003cli\u003eComputer printers and plotters\u003c\/li\u003e\n\u003cli\u003eNon-contact object\/interrupt detection\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Powered by INFINITY WORKS","offers":[{"title":"Default Title","offer_id":47371691491382,"sku":"TW252","price":20.4,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0772\/9335\/5062\/files\/MOC7811_OPTO_SENSOR.webp?v=1787646109","url":"https:\/\/tecwizdom.com\/products\/moc7811-opto-sensor","provider":"Tecwizdom.com","version":"1.0","type":"link"}
