SSF67A50A250 is a dual-level stainless steel float switch designed for empty tank control applications, featuring a 50mm upper switching level and 250mm lower switching level with a total length of 277mm. Constructed from 316 grade stainless steel with a nitrile sealing gasket, this switch operates at process temperatures up to 135°C and supports a maximum pressure of 10 bar (up to 500mm length). The switch provides make-on-rise operation at the upper level and make-on-fall operation at the lower level, with electrical ratings of 250V AC maximum switching voltage, 120V DC maximum, and 0.6A maximum switching current at 25VA. The internal mounting design with M16x2 thread, 100cm standard cable length with 7/0.2 tinned copper conductors, and close tolerance switching make it ideal for tank level monitoring and control in industrial and hygienic liquid applications.
