Product Description
The RS PRO LLF40 is a threaded nitrile rubber (NBR) float switch designed for reliable liquid level detection and control in various industrial and commercial environments. This float switch features a compact form factor, making it suitable for applications where space is limited and fluid levels are low.
Equipped with both normally open (NO) and normally closed (NC) switching outputs, the LLF40 can operate at a maximum of 240 V AC and 120 V DC with a current capacity up to 600 mA. The device is encased in a robust polypropylene housing, offering resistance to chemicals, corrosion, and mechanical wear, while the nitrile rubber (NBR) gasket ensures a secure liquid seal and compatibility with most commonly used fluids. The switch is supplied with a 1 meter PVC cable for flexible electrical installation.
Engineered for threaded mounting, the LLF40 is easy to install on the interior wall of tanks, containers, and process vessels, and can be reversed 180 degrees for flexible switch action depending on system requirements. The wide operating temperature range from -20°C to 100°C makes this float switch suitable for harsh environments where temperature variations are frequent.
Typical applications include monitoring and controlling fluid levels in vending machines, commercial washing machines, evaporator units, and other process control or automation systems. Its compact design makes it ideal for size-sensitive deployments and lower specific gravity liquids.
The device does not carry hazardous area certifications but meets general electrical safety standards essential for most non-hazardous industrial applications.
For users seeking robust, responsive fluid level controls in demanding environments, the RS PRO LLF40 delivers reliable operation and proven performance in a durable, easy-to-install package.
