{"title":"4-Wire Slot Type Photoelectric Switch","handle":"4-wire-slot-type-photoelectric-switch","url":"/products/4-wire-slot-type-photoelectric-switch","description":"A 4-wire slot-type photoelectric switch with integrated optical transmitter and receiver. The 5mm detection slot can detect objects passing through, including transparent materials, making it ideal for counting, position sensing, and high-speed object detection in industrial and hobby applications.\n\nThe module operates on 10–30V DC with PNP output and provides both normally open (NO) and normally closed (NC) connections simultaneously. Built-in short-circuit, overload, and reverse-connection protection ensure reliable operation. An onboard LED indicator shows detection status in real time.\n\nKey Features\n\n\nIntegrated Optical Transceiver – Stable performance with strong anti-interference capability\n\nNO and NC Outputs – 4-wire connection provides both normally open and normally closed outputs\n\n500Hz Switching Frequency – Suitable for high-speed counting and detection\n\nFast Response – Less than 1.5ms response time\n\nLED Status Indicator – Real-time visual feedback of detection state\n\nBuilt-In Protection – Short-circuit, overload, and reverse-connection protection\n\n\nSpecifications\n\n\nPower Supply – DC 10–30V\n\nDetection Distance – 5mm (slot width)\n\nOutput Mode – PNP (4-wire)\n\nSwitching Frequency – 500Hz\n\nResponse Time – <1.5ms\n\nProtection Rating – IP50\n\nDimensions – 26.2 × 25 × 7mm\n\n\nWiring\n\n\nBrown – Positive (+)\n\nBlue – Negative (−)\n\nBlack – Normally closed (NC) output\n\nWhite – Normally open (NO) output\n\n\nIdeal For\n\nObject counting and material detection\nTransparent object detection\nEnd-stop and position sensing\nHigh-speed event counting\n\n\nPackage Contents\n\n1× 4-Wire Slot Type Photoelectric Switch\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":2682,"title":"Default Title","sku":"DF-SEN0448","price":11.35,"on_sale":false,"in_stock":true,"available_quantity":26,"option1":"Default Title"}]}
