Sonoma Forge sensor faucet technology is called "Sans Hands", and it has a different name because it is not what you're accustomed to. San Hands has no visible sensors and does not rely on old, unreliable infrared technology. All you see is the faucet and water that runs when it's supposed to run, without the frantic hand-waving.
Sonoma Forge products are hand-made in the USA, not mass produced. Each faucet is
unique and individual and may vary in dimension from one item to another.
