Dwyer F7-EBNC level switches are designed for general purpose use with compatible liquids. They have a temperature range of -4 to 257°F (-20 to 125°C) for the F6-SS and F6-MHS models, and 14 to 176°F (-10 to 80°C) for the F6-HPS-11, 21, 31 models. The switches feature SPST hermetically sealed reed switches that are reversible for NO or NC operation. The wetted material varies based on model and the pressure limit is 218 psi (15 bar) for F6-SS and F6-MHS, and 116 psi (8 bar) for F6-HPS-11, 21, 31. The electrical rating is 20 VA with 0.17 A at 120 VAC and 0.08 A at 240 VAC. Mounting options include 1/8" NPTM for vertical mount and 1/2" NPTM, M16 x 2, or 1/2" x 13 thread depending on the model. The switches are available with wire leads ranging from 18" to 39" in length. The specific gravity varies for each model, with F6-SS at 0.65, F6-MHS at 0.85, and F6-HPS-11, 21, 31 at 0.6. The magnets used in the switches are either alnico or ceramic, depending on the model. Overall, these level switches offer reliable performance for various application needs.
