No, the sensor is designed to detect labels on a web with a grounded backplate. The sensor needs a grounded reference surface behind the labels. The built-in base plate can be removed and another surface can provide this reference. If the original baseplate is not used, the substitute reference surface must provide a stable gap. Vibration or thermal growth relative to the sensor will introduce potential error or require more frequent re-adjustment.
Outputs are short circuit protected.
Voltages over 100V may exceed the protection capacity and damage the sensor. All sensors have a maximum current draw of 50ma. Optimum performance is obtained with 24VDC operation. Capacitance Theory Applications 563 Shoreview Park Rd.
