L4-SS-AT, Series L4 FLOTECT® Float Switch, 316 Stainless Steel Body (430SS Magnet Keeper), ATEX Approval
Rugged and reliable the SERIES L4 Flotect® Float Switch operates automatically to indicate tank level. Perfect for starting or stopping pumps, opening or closing valves, or actuating level alarm signals. A unique magnetically actuated switching design gives superior performance. There are no bellows, springs, or seals to fail. Instead, the free-swinging float attracts a magnet within the solid metal switch body, actuating a snap switch by means of a simple lever arm. Float arm hinge design limits the arm angle to prevent vertical hang up.
Features:
- Leak proof body machined from bar stock
- Weatherproof, designed to meet NEMA 4
- Explosion-proof
- Installs directly and easily into tank with a threaded branch connection or flange
- Electrical assembly can be easily replaced without removing the unit from the installation so that the process does not have to be shut down

The temperature class is determined by the maximum ambient and/or process temperature. Units are intended to be used in ambient of -20°C ≤Tamb≤73°C. Units may be used in process temperatures up to 133°C providing the enclosure and switch body temperature do not exceed 73°C. The standard Temperature Class is T6 Process Temp ≤73°C
