The KN18E014 is a capacitive sensor manufactured by IPF ELECTRONIC. It has a range of 1 - 10 mm and works at an input voltage of 20 - 250 VAC or 20 - 250 VDC. It is designed to detect the presence of objects in an automotive, industrial, scientific or home automation application. This sensor is highly accurate and robust. It has several advantages, such as a nonsaturating voltage ratio, insulation resistance and a minimum snap-action distance. Additionally, there are several types of output such as N/C, N/O, PTC, relay etc. which can be easily changed. The KN18E014 is well suited for both commercial and industrial applications.
