Sensor Tap

No Touch Automatic Sensor Taps incorporate state-of-the-art design and technology to provide the ultimate in convenience. In addition, they offer the added benefit of improved hygiene by eliminating the need to physically touch the fixture to turn the water on or off. This eliminates the chance of re-contaminating one’s hands by touching the same handle that was previously touched by not only your own unwashed hands, but those of every user who came before you. Sensor taps are very simple to operate. The sensor detects hand movements and turns the tap on for use, then turns it off after no movement is detected for a specific amount of time.

The solenoid valve is initially energized to start the water flow; the plunger is driven into the range of a permanent magnet which in turn holds
the plunger in the "open" position. In order to return the plunger into its original "closed" position
the solenoid is once again "pulsed" but this time by reversing polarity.
