Capacitive sensors detect both metal and non-metal objects, and can sense through insulating materials such as wood or plastic. They are often used to detect fill levels of liquids, pellets, and powders through container walls. Capacitive sensors are available in cylindrical or rectangular shapes, with sensing distances up to 40mm.
AutomationDirect offers a variety of capacitive sensors that allow sensing of metal and non-metal objects, even through non-metal containers. Sensing distances range from 1.5-15mm flush and 2-40mm non-flush. NPN and PNP logic outputs and normally open or normally closed output models are available. All capacitive proximity sensors have LED status indicators to verify operation at the switch; and all capacitive proximity sensors are IP65 or IP67 rated.
