Capacitive Sensors .

Capacitive Sensors: Plastic / Metal Cylinder M18, M30 and Plastic Square

ELCO capacitive sensors detect metallic and non-metallic objects, liquids and bulk materials. The range includes M18 and M30 cylinders in PBT or stainless steel housings (48 models each), flat rectangular 50 × 30 × 7 and 50 × 20 × 10 mm types, and pipeline liquid-level sensors. Sensing range 8–22 mm (e.g. FC15-KM30-BN6L — 15 mm), NPN/PNP NO/NC outputs, 10–30 V DC supply, IP67, −25…+70 °C.

Applications

Level detection of bulk materials and liquids in hoppers and tanks
Detection of non-metallic products and packaging on conveyors
Liquid presence monitoring in pipelines
