The AT 120 HR HY is a heavy duty float level switch designed for aggressive liquids. This float is encased in a HR HY (High Resistance) press-vulcanised housing, which ensures a double waterproof. The AT 120 HR HY can be connected directly to pumps up to 1.5 HP or through a relay if working with high power pumps. Its wide switching angle of 120º protects the pump's engine and the electrical panels from jerking, specially when dealing with very agitated liquids.
Advantages
- 120º switching angle that protects the pump's engine from jerking
- Double waterproof thanks to its HR HY (High Resistance) housing
- No maintenance needed, thanks to its biconical shape that avoids any clogging
- Easy to install, easy to use
- Ecological float switch (no mercury, no lead)
Applications
- Aggressive liquids : acids, solvents, corrosive liquids, hydrocarbons, sea water, etc...
- Emptying / Filling function
- Overflow or dry-running protection
- High / low level alarm

Remarks
It is highly recommended to use external ballasts and cable hangers with our float level switches. For pump control of several levels with several pumps in aggressive liquid applications, choose our SOBA Hypalon float level switch. If your installation is located in a hazardous area, choose our ATEX certified float switch SOBA EX.
