Carlo Gavazzi CD34CNFLFNCP2 - Capacitive Sensor - Rectangular Plastic Housing Length 34mm - Neutral - Flush Mounting - Liquid Level - Foreground Suppression - NPN, N.C. Output - 2m PVC Cable

Description
The CD34.. capacitive sensor is designed for detecting water-based (conductive) liquids through a non-metallic container wall, and it automatically adapts to various thicknesses of plastic or glass walls.

The universal mounting brackets allow the sensor to be fixed on various tubes or containers.

Strong, compact housing with IP69K ratings and 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.

Main features
• Compact housing
• Supply voltage: 10 to 30 VDC
• Output: 100 mA, NPN or PNP preset
• Make or break switching function

• 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
• Detection of water-based fluids inside a container or tube without direct contact with the fluids.
• The sensor detects the liquids reliably while compensating for residue film, moisture or foam build-up from liquids such as water, milk, body fluids (blood), acid- or alkaline solutions with conductivity as high as 50 mS/cm inside or outside the container wall.
• Flexible and fast universal mounting bracket.
• The sensing principle detects only the level of the liquids while ignoring foam, film or build-up that would cause standard capacitive sensors to detect faultily
