Product Overview
The Sensata RSF50 series offers compact, vertically mounted float switches with a single switch point. Designed for internal tank mounting, either from the top or bottom, these devices require access to the tank's interior. They are suitable for a wide range of applications including vending machines, printing systems, and chemical dosing equipment. Manufactured from various plastics with a selection of gasket materials, the RSF50 series can accommodate most commonly used liquids. The switch action can be reversed by inverting the float on the stem. Available with M12 x 1.75 or 1/8NPT mounting threads, these switches are offered in 25VA and 100VA versions, with many variants being UL recognized components.
