The Baumer CFDM 20N3500/S35L 10119701 is a flush-mounted, contactless capacitive sensor with a nominal sensing distance of 5 mm. It features a GND electrode and operates within a voltage supply range of 10 to 30 VDC. The sensor has a maximum current consumption of 20 mA and supports an output current of 200 mA with an NPN break function (NC) output circuit. It is equipped with a 4-port LED output indicator and offers a switching frequency of 50 Hz. The sensor is designed for detecting non-conductive media and bulk goods, and can detect fill levels through containers, though it is not suitable for liquids in direct contact. Key protections include short circuit and reverse polarity protection. The robust, rectangular brass nickel-plated housing measures 20 mm in width and 35 mm in length, and includes an M8 connector. It operates in temperatures ranging from -25 to +75 °C and is rated IP 65 for dust and water resistance.
