{"title":"Capacitive Proximity Sensor  (1-10 mm)","handle":"capacitive-proximity-sensor-1-10-mm","url":"/products/capacitive-proximity-sensor-1-10-mm","description":"A capacitive proximity sensor with an adjustable detection range of 1–10 mm, capable of detecting both metallic and non-metallic objects. Unlike inductive sensors that only respond to metals, this capacitive sensor detects anything with sufficient dielectric properties — including plastics, wood, glass, liquids, and more.\n\nHoused in a fully enclosed PBT plastic shell with IP67 waterproof and dustproof protection, it operates on a 10–30V DC supply and outputs a PNP normally-open (high-level) signal. Built-in short circuit, overload, and reverse polarity protection make it reliable for industrial and hobbyist applications alike.\n\nKey Features\n\n\nDetects Metals & Non-Metals – Capacitive sensing works with plastics, wood, glass, liquids, and metals\n\nAdjustable Range – 1–10 mm for non-metals, up to 20 mm for metals\n\nIP67 Rated – Waterproof and dustproof PBT plastic enclosure for indoor or outdoor use\n\nBuilt-In Protection – Short circuit, overload, and reverse polarity protection\n\nStatus Indicator – LED provides real-time detection feedback\n\nFast Response – Less than 1.5 ms response time with 50 Hz switching frequency\n\n\nSpecifications\n\n\nPower Supply – DC 10–30V\n\nDetection Distance – 1–10 mm adjustable (up to 20 mm for metal, 10 mm for non-metal)\n\nOutput Mode – PNP normally open (high-level output)\n\nSwitching Frequency – 50 Hz\n\nResponse Time – <1.5 ms\n\nSwitch Hysteresis – <15%\n\nRepeatability – <5.0%\n\nOperating Temperature – −25°C to +70°C\n\nProtection Rating – IP67\n\nDimensions – 50 × 20 × 10 mm\n\nWiring – Brown (V+), Blue (V−), Black (Signal Output)\n\n\n\nNote: Factory standard detection object is a 20 × 20 × 1 mm pure iron block. Actual detection distance varies with the size, thickness, and conductivity of the target object — larger, thicker, and more conductive objects are detected at greater distances.\n\n\nIdeal For\n\nObject detection and presence sensing\nMechanical automation and robotics\nLiquid level detection through non-metallic containers\nSecurity equipment and access control\n\n\nPackage Contents\n\n1× Capacitive Proximity Sensor\n1× Screwdriver (for adjustment)\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":2613,"title":"Default Title","sku":"DF-SEN0447","price":21.83,"on_sale":false,"in_stock":true,"available_quantity":164,"option1":"Default Title"}]}
