CD34CNFLFPCT5 is a capacitive sensor with foreground suppression designed for detecting water-based (conductive) liquids through non-metallic container walls such as plastic or glass. It features a PNP normally closed (N.C.) output configuration with a 0.3 m M8 4-pin male pigtail connection, operating on a 10-30 VDC supply voltage with up to 100 mA output current. The sensor automatically adapts to various wall thicknesses (0.5-6 mm plastic, 0.5-4 mm glass) and compensates for residue film, moisture, or foam build-up while detecting liquids with conductivity up to 50 mS/cm. Housed in a compact PC/PBT body with dimensions of 8 x 16 x 34 mm, it offers IP65, IP66, IP67, IP68, and IP69K protection ratings with ECOLAB approval for wash-down applications. This sensor is ideal for level detection in food and beverage, pharmaceutical, and industrial applications requiring reliable non-contact liquid sensing.
