Description
CFAK series capacitive proximity sensors are designed for reliable non-contact detection of solid and liquid materials, including powders, granules, plastics, glass, wood, and fluids. Using capacitive field variation, they detect objects regardless of color or transparency and can sense through non-metallic container walls. With adjustable sensitivity, compact housing, and robust industrial design, CFAK sensors are ideal for level monitoring, presence detection, and material flow control in process and automation applications.
