Product Overview
The Sensata RSF50 series offers compact, vertically mounted float switches designed for single switch point applications. These internal-fitting devices can be mounted from the top or bottom of a tank, requiring access to the inside. Ideal for vending machines, printing systems, and chemical dosing equipment, the RSF50 series is manufactured from a variety of plastics with selectable gasket materials to suit common liquids. The switch action can be reversed by inverting the float. Available with M12 x 1.75 or 1/8NPT mounting threads, these switches are offered in 25VA and 100VA versions, with many models being UL recognized components. WRAS and NSF approved versions are also available.
