Faucet Sensing Technologies:Power source

All touchless faucets require a power source. Some models draw power from batteries, while others use a low-voltage current from an AC transformer or AC/DC voltage adapter. Most faucets use a low voltage DC latching (also known as bi-stable) solenoid valve that “latches” in the open position without further electric current until a pulse of power “un-latches” it, allowing it to return to the closed position.

It is important to point out the battery life is not the same for AIR and capacitance sensing faucets. Both AIR and capacitance sensing use the same solenoid valve technology. In the worst case scenario of 8,000 cycles per month at high water pressure, the battery life of an AIR or capacitance sensing faucet can be up to five years without employing power harvesting techniques.

Electronic faucets have come a long way and continue to evolve as effective tools for improving hygiene while maximizing water efficiency. By employing multiple sensing technologies, we are able to offer a variety of faucets tailored to any environment.
