Description
The Littelfuse LLC14B60AX is a precision-engineered, single-probe conductive liquid level control relay built for dependable fluid monitoring and automated level management across a wide range of commercial and industrial systems. Operating on 120VAC, it employs a safe low-voltage AC sensing method to accurately detect liquid presence via a single probe — enabling precise ON/OFF control of pumps or valves without complex wiring or setup.
A built-in fixed 60-second time delay safeguards against rapid short-cycling, extending equipment life and maintaining system stability in demanding environments. Whether managing fill cycles, preventing dry-run pump conditions, or protecting against overflow, this compact control board delivers consistent, worry-free performance.
Its space-saving PCB form factor makes it ideal for OEM integration and control panel installations, while its proven reliability makes it a trusted choice for HVAC systems, boilers, water treatment equipment, and industrial fluid management applications.
