Products AutomationDirect sensors
The AutomationDirect line of sensors now includes capacitive proximity sensors with potentiometer adjustment for sensitivity. Capacitive proximity sensors allow sensing of metal and non-metal objects through insulating materials such as wood or plastic and are often used to sense fill levels of liquids or powders.
The new AutomationDirect lower-priced 18 and 30 mm capacitive proximity sensors have a simple potentiometer sensitivity adjustment.
Operating voltages are 10 to 30 Vdc; shielded and unshielded versions and NO or NC units are available. Existing capacitive sensors have a pushbutton teach function. T
he CK2 series 18 mm capacitive sensors with IP65/IP67/IP69K ratings provide an unshielded sensing distance up to 15 mm.
The 30 mm DC-powered CT2 series capacitive sensors have metal (IP65 rated) or plastic (up to IP69K rated) housings with sensing distances up to 25 mm.
The sensors are cULus and CE approved.
