NCS-10

Through Wall Capacitive Sensor

Non-Contact, Thin Profile Level Sensor

Series NCS-10 Through Wall Capacitive Sensor features a thin profile with a sens­ing distance of 10 mm non-flush mounted. The switching points can be altered by means
of the push-button teach-in function. 3-wire DC output with selectable make (NO) or break
(NC) switching and NPN Alarm. The NCS-10 is designed for front, pipe or plane mount­ing. Capacitive sensors can detect metallic as well as non-metallic objects; however, their
traditional use is for non-metallic materials such as: plastics industry, chemical industry,
wood industry, ceramic and glass industry, and packing industry.

FEATURES
