CD34CNFLFxxx Capacitive sensor, Foreground Suppression Main features Compact housing Supply voltage: 10 to 30 VDC Output: 100 mA, NPN or PNP preset Make or break switching function LED indication for output and power ON Protection: reverse polarity, short circuit and transients Cable and pigtail M8 plug versions Excellent EMC performance IP65, IP66, IP67, IP68 and IP69K for hose-down applications cULus Ecolab Main functions Description Detection of water-based fluids inside a container or tube without direct contact with the fluids. The CD34.. capacitive sensor is designed for The sensor detects the liquids reliably while compensating detecting water-based (conductive) liquids through for residue film, moisture or foam build-up from liquids a non-metallic container wall, and it automatically such as water, milk, body fluids (blood), acid- or alkaline adapts to various thicknesses of plastic or glass solutions with conductivity as high as 50 mS/cm inside or outside the container wall. walls. Flexible and fast universal mounting bracket. The universal mounting brackets allow the sensor The sensing principle detects only the level of the liquids to be fixed on various tubes or containers. while ignoring foam, film or build-up that would cause Strong, compact housing with IP69K ratings and standard capacitive sensors to detect faultily. ECOLAB approval for wash-down applications. The sensor will function out of the box in most applications, and teach-in capabilities are available for adapting the sensor to more challenging applications. 03/08/2020 CD34CNFLFxxx ENG Carlo Gavazzi Industri A/S 1CD34CNFLFxxx References Product selection key CD34CNFLF Enter the code option instead of Code Option Description C - Capacitive sensor D - Rectangular housing 34 - Length of housing C - Plastic housing N - Neutral F - Flush mounting L - Liquid level F Foreground suppression N NPN P PNP O N.O.
