It shines a light beam out into the open space. When an object crosses that beam of light, the light bounces back to the eye (sensor). The sensor then sends an electrical signal. This tells a machine to stop, start, or count.\u003c\/span\u003e\u003cspan\u003eBackground suppression is a special feature. It acts like wearing blinders on a horse. The sensor ignores objects that are far away. It only looks for objects inside its set 200 mm range. This stops the sensor from getting confused by walls or machines in the background.\u003c\/span\u003e\u003cspan\u003eThe PD30CNB20NASA\u003c\/span\u003e\u003cspan\u003e provides an NPN output\u003c\/span\u003e\u003cspan\u003e. In simple terms, this means it acts like a switch that connects to ground (negative). When the sensor sees an object, it pulls the electrical signal to zero volts. This signals the machine or robot (like a PLC or microcontroller) that an object is presen\u003c\/span\u003e\u003c\/p\u003e","brand":"QYSMT","offers":[{"title":"Default Title","offer_id":47981522452619,"sku":null,"price":0.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0568\/9579\/9435\/files\/PD30CNB20NASAProximitysensor_1.png?v=1783752565","url":"https:\/\/www.qysmt.in\/products\/pd30cnb20nasa-diffuse-reflective-photoelectric-sensor","provider":"QYSMT","version":"1.0","type":"link"}
