FineTek FF Series Side Mounting Float Level Switch

The Finetek FF series is a side mount magnetic float level switch product line consisting of rugged, industrial-grade float level switches using the principles of buoyancy and magnetism to provide high, low, and intermediate level detection of fluids with a specific gravity ranging from as low as 0.25, thereby ensuring a very wide range of application and use. A change in fluid level can correspondingly cause the float to travel up or down. The FF series side-mounted magnetic float level switch product line incorporates SPDT reed switch or SPDT microswitch output and is available in stainless steel or polypropylene wetted materials. Marine certification and explosion-proof versions are available.
