An inductive sensor, or inductive proximity sensor, detects metal objects without contact. It is used as a wear-free limit switch and for position, presence and speed detection on machines, conveyors, robots and mobile equipment. With no moving parts it keeps working in dirt, oil and vibration. SCN supplies inductive sensors from Wenglor, sensors in the AE1, AK1, AM1, AT1, VK2, VM2 and VT2 series, and P-Prox sensors in PEEK from Petercem for extreme temperatures.<\/p>\n
The range covers cylindrical housings from M8 to M30 as well as cubic and miniature formats, flush and non-flush mounting, and sensing distances from 1.5 mm up to 30 mm. Outputs include PNP and NPN, NO and NC, analog 0\u201310 V and IO-Link. There are stainless steel versions with IP69K for washdown, weld-field immune models and sensors with a separate evaluation unit for hot environments. For longer distances or non-metallic objects, see photoelectric sensors<\/a>; for detecting magnets, see Hall effect sensors<\/a>. All sensor types are listed under Sensors<\/a>.<\/p>\n How to choose:<\/strong> start with the housing size and sensing distance, and whether the sensor will be mounted flush in metal. Then choose the output (PNP or NPN, NO or NC, analog or IO-Link) and the connection (cable or M8\/M12 connector), and check the IP rating and temperature range.<\/p>\n An inductive sensor generates a high-frequency electromagnetic field at its sensing face. When a metal object enters the field, eddy currents are induced in it and dampen the oscillator; the electronics detect the change and switch the output. Because only metal affects the field, the sensor ignores plastic, wood and liquids, and it works without contact or wear.<\/p><\/details>\nFrequently asked questions<\/h3>\n
