High-performance SICK CM18-08BNP-EC1 (6058147) capacitive sensor. Features 8mm sensing range, flush mounting, NPN output, and IP68/IP69K protection for harsh environments.
The SICK CM18-08BNP-EC1 is a high-performance capacitive proximity sensor designed for the non-contact detection of metallic and non-metallic objects, including liquids, powders, and granulated materials. As part of the advanced CM product family, this sensor is engineered to operate in demanding industrial conditions where dust, moisture, and electromagnetic interference (EMC) are prevalent. Its robust PBT plastic housing is Ecolab-certified, making it highly resistant to aggressive cleaning agents and suitable for hygienic environments.
With an adjustable sensing range of up to 8 mm, the CM18-08BNP-EC1 provides superior flexibility for various automation tasks. The sensor features an integrated 11-turn potentiometer for precise sensitivity tuning, allowing users to calibrate the device to detect specific media through non-metallic container walls. Its dual LED indicators provide immediate visual feedback on the switching state and signal stability, ensuring a fast and error-free setup. The IP68 and IP69K ratings guarantee durability during high-pressure washdown cycles, while its enhanced EMC resistance prevents false switching near frequency converters or other electrical noise sources.
