The SICK CS81-P3612 is a heavy-duty capacitive proximity sensor designed for non-contact detection of solid and liquid materials through non-metallic containers. It detects objects by measuring changes in capacitance, making it ideal for level sensing and material presence applications in harsh industrial environments.
