{"title":"5V IR Photoelectric Switch (4m)","handle":"5v-ir-photoelectric-switch-4m","url":"/products/5v-ir-photoelectric-switch-4m","description":"This IR break-beam photoelectric switch detects objects by sending an invisible infrared beam from an emitter to a receiver. When a non-transparent object passes between the two and breaks the beam, the receiver outputs a signal. It works over distances up to 4 metres with a fast 0.5ms response time.\n\nPowered by 5V DC, this sensor is compatible with Arduino and other microcontrollers for motion detection, speed measurement, timing, and counting applications. Its compact size allows installation in tight spaces.\n\nKey Features\n\n\nSensing Range – Up to 4 metres (thru-beam, non-transparent objects)\n\nOperating Voltage – DC 5V\n\nResponse Time – 0.5ms\n\nWavelength – 830nm (infrared)\n\nReceiving Angle – ±5°\n\nOutput Current – 30mA\n\nOutput Power – 100mW\n\nOperating Temperature – −10°C to +60°C\n\nStorage Temperature – −20°C to +80°C\n\n\nWiring\n\n\nTransmitter (green PCB) – Red: 5V, Black: GND, Green: floating\n\nReceiver (black PCB) – Red: 5V, Black: GND, Blue: signal output\n\n\nIdeal For\n\nMotion detection and object counting\nSpeed measurement and timing gates\nRobot runway conversion and line tracking\nSmart robot competitions\n\n\nPackage Contents\n\n1× 5V IR Photoelectric Switch (transmitter + receiver pair)\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":1707,"title":"Default Title","sku":"DF-SEN0523","price":20.18,"on_sale":false,"in_stock":true,"available_quantity":15,"option1":"Default Title"}]}
