Delta Faucet’s Proximity Sensing Technology enables easy operation of the faucet by forming a 4-inch field around the body of the faucet. When the user’s hand enters the field, the faucet is turned on. When the user removes his hands from the water stream, the faucet turns off within 2 seconds. The designs, free of optics and infrared, are easy to maintain due to their clean lines and are able to fit a variety of designed spaces.
