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 2-15mm shielded and 2-40mm unshielded. 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. ZIPport multi-port junction blocks provide a simple and effective way to organize sensor wiring. Field wireable connectors and T-couplers can be used to make custom patch cable lengths from existing cables/bulk wire or turn a prewired sensor into a quick disconnect.
