It works by emitting a light beam and analyze how the light interacts with the target object. These sensors are widely used in industrial automation, manufacturing, and safety systems due to their non-contact operation, reliability, and versatility.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eWhat will I get?\u003c\/strong\u003e\u003cbr\u003eDiffuse Photoelectric Sensor\u003cbr\u003eWire Size: 4.7mm x 116cm \/ 0.19 x 45.67 inch (OD x L);\u003cbr\u003eTerminal Wire Dia: 1.6mm \/ 0.06 inch;\u003cbr\u003eThread Size: M18;\u003cbr\u003eRated Voltage: DC 6-36V\u003cbr\u003eRated Current: 300mA;\u003cbr\u003eSensing Distance: 30cm \/ 11.81 inch;\u003cbr\u003eOutput State: NPN NC;\u003cbr\u003eIn the package of: 1pcs x Adjustable Diffuse Photoelectric Sensor\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eAre there any advantages of this product?\u003c\/strong\u003e\u003cbr\u003eNPN NC (Normally Closed): By default (no object), the NPN transistor is on, keeping the output closed (current flows). When an object blockages the beam, the transistor turns off, opening the circuit and stopping current flow. Used for safety or fail-safe systems.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eHow to use it?\u003c\/strong\u003e\u003cbr\u003eTo use a photoelectric sensor: Mount and align it so the light beam hits the target. Wire it correctly (NPN = connects to ground, PNP = connects to +V). Adjust sensitivity if needed. Test by blocking the beam—the sensor’s LED or output signal will confirm detection.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eWhat should I notice?\u003c\/strong\u003e\u003cbr\u003eKeep the sensor clean and avoid bright ambient light that might interrupt the detection result.","brand":"Harfington","offers":[{"title":"Default Title","offer_id":67266851307769,"sku":"a25040800ux2560","price":14.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0595\/2477\/6095\/files\/ux_a25040800ux2560_ux_g03.jpg?v=1790870040","url":"https:\/\/www.harfington.com\/en-au\/products\/p-1888086","provider":"Harfington","version":"1.0","type":"link"}
