Description
The Baumer CFAK 12N1140/KS35L 11039126 is a liquid level sensor designed for wastewater applications. It features a nominal sensing distance of 0.1 mm and is non-flush mounted. This sensor does not include a GND electrode and has a temperature drift of ±20%. It lacks sensitivity adjustment and cannot detect non-conductive media or detect fill levels through containers. It is designed for direct contact with liquids but is not suitable for object detection or bulk goods. The sensor operates with a voltage supply range of 10 to 30 VDC, a maximum no-load current consumption of 12 mA, and an NPN make function (NO) output circuit with a maximum output current of 200 mA. The voltage drop is less than 2.5 VDC, and it has a switching frequency of 15 Hz. It includes short circuit and reverse polarity protection. The cylindrical threaded design is made from POM with a screw nut and gasket also in POM and EPDM50, respectively. Dimensions include a 12 mm diameter and a 39.5 mm housing length. It connects via a flylead connector M8, L=200 mm, operates within a temperature range of 0 to +50 °C, and is rated IP 67 for protection against dust and immersion.
