Sick Capacity Sensor 6020479 with Waste Bottle Setup Attachment

SICK CQ35-25NPP-KC1 Capacitive Proximity Sensor (6020479) with Waste Bottle Mount Attachment

The SICK CQ35-25NPP-KC1 Capacitive Sensor (Part No. 6020479) is an industrial-grade non-contact liquid level sensing solution engineered for accurate level monitoring through non-metallic container walls. Utilizing an advanced capacitive detection field with a 25 mm sensing range, this sensor detects conductive liquids, water-based solutions, and chemical reagents inside plastic, glass, or PTFE waste bottles without direct contact with the fluid. Featuring a rugged rectangular housing and a PNP complementary (NO + NC) switching output, it easily integrates into automated laboratory waste management systems, bioprocessing liquid handling carts, and HPLC waste containment monitoring setups. Supplied with a specialized waste bottle mounting attachment bracket, this unit enables quick, secure installation directly onto fluid collection vessels to prevent overflow hazards and maintain biosafety compliance.

Technical Performance & Structural Attributes

• Non-Contact Level Sensing Through Wall: Accurately detects liquid levels through plastic or glass vessel walls, eliminating sensor chemical corrosion and fluid contamination risks.
• Complementary PNP Output Architecture: Features both Normally Open (NO) and Normally Closed (NC) switching contacts for flexible integration with control PLCs, alarms, or cut-off relays.
• Adjustable Potentiometer Sensitivity: Allows precise calibration to ignore wall thickness or foam buildup and trigger strictly on liquid level volume thresholds.
• Rugged Industrial Housing: IP67-rated enclosure resists harsh chemical splash environments, ambient humidity, and mechanical vibration.
• Dedicated Bottle Attachment Mount: Includes a custom-fit mounting collar/bracket assembly designed to clamp securely around standard laboratory waste carboys and collection bottles.
