Product Overview
The Sensata RSF50 Series offers compact, internally fitted vertical float switches designed for single switch point applications. These devices are mounted from the inside of a tank, either from the top or bottom, requiring access to the tank's interior. Ideal for vending machines, printing systems, and chemical dosing equipment, the RSF50 series is available in various plastic materials and gasket options to accommodate commonly used liquids. The switch action can be reversed by inverting the float. Mounting threads are available in M12 x 1.75 or 1/8NPT. Many variants are UL recognized components, with WRAS and NSF approved options available.
