e-ON is the latest hands free faucet design from Sonoma. What's unusual about these automatic faucets is that they employ electromagnetism for a quick hands free action. The design is free of unreliable infra-red sensors commonly used in automatic faucets, as there is no need to wave hands to make it work. The spout itself serves as the sensor. It's available in six elegant faucet styles and it reliably works every time as long as it is properly installed.
