The Pepperl + Fuchs LFL2-CK-U-PUR5 is a high-quality float switch designed for reliable limit value detection in a variety of fluid applications. This mercury-free microswitch is integrated within a durable polypropylene float and is triggered by deviations from its horizontal position, ensuring precise operation and control. The switch features a small sleeve design that allows for mounting through a G1 tap hole, making it versatile for different installation requirements.
With an electrical life of over 50,000 switching cycles and a pulse withstand voltage of 4 kV, this sensor is built for longevity and resilience in challenging environments. It operates effectively within an ambient temperature range of 5 to 70°C and can handle process pressures up to 3 bar at 20°C. The LFL2-CK-U-PUR5 is also equipped with a highly flexible 5-meter PUR cable, which contributes to its ease of installation and robustness.
The device's IP68 degree of protection ensures it is dust-tight and can withstand immersion under water, making it suitable for a wide range of industrial applications. Whether used for monitoring levels in tanks containing fuels, heating oils, or other oily fluids, this float switch is an excellent choice for precise and dependable fluid level control.

What is the function of this float switch?
The float switch is designed to detect the limit value of fluids within a container. It contains a microswitch that is activated when there is a deviation from the horizontal position, indicating a change in the fluid level.
Can this float switch be used with any type of fluid?
The float switch is suitable for use with a range of fluids, particularly those with a density of 0.8 g/cm3 or higher. It is preferred for use with fuels, heating oils, and oily fluids.
What are the electrical specifications of this float switch?
The float switch can handle contact loading of 250 V AC/3 A with a resistive load, 150 V DC/0.25 A resistive load, and 60 V DC/1 A resistive load. It has a rated insulation voltage of 300 V and a pulse withstand voltage of 4 kV.
How is the float switch installed?
The float switch can be mounted from the side through a cable gland of size G1A or from the top using a counter weight or rods. The pivot of the cable should always be horizontal to ensure proper functioning.
What is the operating temperature range for this float switch?
The operating temperature range for the float switch is between 5 to 70 degrees Celsius (41 to 158 degrees Fahrenheit).
What is the degree of protection provided by this float switch?
The float switch is rated with a degree of protection of IP68, indicating that it is dust tight and can withstand immersion in water under specified conditions.
What materials are used in the construction of this float switch?
The float of the switch is made from Polypropylene (PP), and the cable is made from highly flexible Polyurethane (PUR) with a cross-section of 3 x 0.50 mm2.
What are the dimensions of the float switch?
The float switch has a diameter of approximately 29.2 mm and a cable length of 5 meters.
How can I ensure the float switch operates correctly?
To ensure correct operation, the float switch should be installed with the pivot of the cable kept horizontal, and the cable length between the fixture and the floating body should be appropriate for the type of cable used.
What accessories are available for this float switch?
Accessories available for the float switch include a gland screw connection (LFL-Z132-EMS) and a ballast weight for the float switch (LFL-Z32-EMS).
