It detects object presence by emitting an infrared beam and receiving the light reflected from the object. It can detect both transparent and opaque objects. An ideal solution for smart car obstacle avoidance, production line product counting, security alarms, automatic door sensors, and various DIY projects.\u003cbr\u003e\u003cbr\u003e⚠️ Important Notes \/ How to Use (Ensure Proper Operation!)\u003cbr\u003e\u003cbr\u003eCorrect Power Supply: Operating voltage is 5V DC. Do not exceed 5.5V or go below 4.5V, which may damage the sensor or cause instability.\u003cbr\u003e\u003cbr\u003eTarget Object \u0026amp; Background Requirements: The detected object surface should preferably be diffuse reflective (e.g., paper, wood). Avoid glossy or black light-absorbing surfaces, as performance will degrade. Keep the sensor’s background farther than the set detection distance.\u003cbr\u003e\u003cbr\u003eAvoid Direct Strong Light: Although resistant to interference, avoid pointing the sensor lens directly at sunlight or strong light sources to maintain optimal performance.\u003cbr\u003e\u003cbr\u003eUnderstand Output Signal: This is an NPN normally open (NO) sensor. Output is HIGH (≈Vcc) when no object is detected, and switches to LOW (≈0V) when an object is detected. Design your microcontroller reading logic accordingly (e.g., use a pull-up resistor or configure as pull-down input).\u003cbr\u003e\u003cbr\u003eAdjustment Method: Power on, place the target object at the desired detection distance. Slowly rotate the potentiometer on the back until the signal LED changes state when the object enters\/leaves the detection zone.\u003cbr\u003e\u003cbr\u003e🔧 Wiring Guide (3-Wire)\u003cbr\u003e\u003cbr\u003eBrown Wire: Connect to VCC (+5V)\u003cbr\u003e\u003cbr\u003eBlue Wire: Connect to GND (0V)\u003cbr\u003e\u003cbr\u003eBlack Wire: Signal output (OUT) – Outputs LOW when object is detected.\u003cbr\u003e\u003cbr\u003e📋 Specifications\u003cbr\u003e\u003cbr\u003eModel: E18-D80NK\u003cbr\u003e\u003cbr\u003eDetection Method: Diffuse Reflective Infrared Photoelectric Switch\u003cbr\u003e\u003cbr\u003eOutput Type: NPN Normally Open (NO)\u003cbr\u003e\u003cbr\u003eOperating Voltage: 5V DC ±0.5V\u003cbr\u003e\u003cbr\u003eDetection Range: 3cm - 80cm (continuously adjustable)\u003cbr\u003e\u003cbr\u003eResponse Time: \u0026lt; 2ms\u003cbr\u003e\u003cbr\u003eOutput Current: ≤ 100mA\u003cbr\u003e\u003cbr\u003eQuiescent Current: \u0026lt; 25mA\u003cbr\u003e\u003cbr\u003eDetectable Object: Transparent or opaque diffuse reflective objects\u003cbr\u003e\u003cbr\u003eAmbient Light Immunity: Sunlight ≤10000 Lux, Incandescent ≤3000 Lux\u003cbr\u003e\u003cbr\u003eOperating Temperature: -25°C ~ +55°C\u003cbr\u003e\u003cbr\u003eBeam Angle: \u0026gt; 15°\u003cbr\u003e\u003cbr\u003eDimensions: Ø17mm, Length 45mm\u003cbr\u003e\u003cbr\u003eCable Length: Approx. 45cm\u003cbr\u003e\u003cbr\u003e📦 Package Includes\u003cbr\u003e1 × E18-D80NK Infrared Photoelectric Sensor\u003c\/p\u003e\n\u003cdiv\u003e\n\u003cimg style=\"width:100%;height:auto\" width=\"100%\" height=\"auto\" src=\"https:\/\/ae01.alicdn.com\/kf\/Se95350a75aba49dab0881a5701308d77t.jpg\" slate-data-type=\"image\"\u003e\u003cimg style=\"width:100%;height:auto\" width=\"100%\" height=\"auto\" src=\"https:\/\/ae01.alicdn.com\/kf\/S6ab6eac4bed9481583c19a68263631ad9.jpg\" slate-data-type=\"image\"\u003e\u003cimg style=\"width:100%;height:auto\" width=\"100%\" height=\"auto\" src=\"https:\/\/ae01.alicdn.com\/kf\/S39e47dbfcc144b5ca07770756b4c1f85v.jpg\" slate-data-type=\"image\"\u003e\u003cimg style=\"width:100%;height:auto\" width=\"100%\" height=\"auto\" src=\"https:\/\/ae01.alicdn.com\/kf\/S843acfd2480e4d91855237f457f23797r.jpg\" slate-data-type=\"image\"\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\u003c\/div\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Yoeruyo","offers":[{"title":"2 pcs","offer_id":55420148547883,"sku":"14:193#2 pcs","price":35.06,"currency_code":"USD","in_stock":true},{"title":"5 pcs","offer_id":55420148580651,"sku":"14:100013777#5 pcs","price":88.88,"currency_code":"USD","in_stock":true},{"title":"1 pcs","offer_id":55420148613419,"sku":"14:10#1 pcs","price":18.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1000\/5744\/8747\/files\/S947a123066394d099653bd0ac158a926m.webp?v=1788499640","url":"https:\/\/yoeruyo.com\/products\/e18-d80nk-infrared-obstacle-avoidance-photoelectric-sensor-switch-3-80cm-adjustable-range-anti-interference-for-smart-car-robot","provider":"Yoeruyo","version":"1.0","type":"link"}
