stainless steel chromed automatic kitchen faucet

Touchless kitchen faucet solution

A touchless kitchen faucet uses active infrared sensor technology that allows you to start the flow of water without touching the faucet. Instead, just place your hand in front of the sensor will start the water flow, and the water will stop when you take your hand away.

Kege provides the whole solution, sensor circuit electronic design, infrared sensor eye shape and sizes, control box, and power supply design. If you want your own regular faucet to turn into a touchless faucet, then KEGE is your best solution, with KEGE electronic key parts, like infrared sensors, solenoid valves, and power supply, it turns your faucet to be a smart touchless faucet.


  • Touchless Motion sensor: Wave the sensor without touch, water flows, wave again, water stops. Water stops automatically after 3mins continuously flow.
  • Sensor STOPS working as long as manual handle activated.
  • Easily replace the batteries without tools.
  • Power detection. Close the solenoid valve automatically when power failure or low power.
  • Low power indication: This may indicate it is time to replace existing batteries with new ones or there is not enough power going to the unit.
  • Sensor distance adjustable by a remote controller.
  • Healthy and Safe: with touch-free faucet for kitchen, it can prevent the spread of bacteria and germs. It’s not only time-saving but also hygienic.

Active infrared sensor

Active infrared touchless sensors use the emission and reception of infrared beams to detect the presence and/or movement of objects or people in their field of detection. The technology is ideal for applications requiring a long and narrow detection range.

The battery box provides the power for all the electronic parts working.


In the future modern smart homes, a touchless kitchen faucet is also one core part. They’re cool, for one thing, as their motion sensors always give you some sort of smart, modern techy feelings. Plus, a touch free faucet keeps your fixture and kitchen clean, it’s a good hygienic choice and decreases the risk of contracting viruses and diseases.

Touchless kitchen faucets use infrared sensor technology that allows you to start the flow of water without touching the faucet. Instead, just placing your hand under the spout sensor, the sensor will give the solenoid valve a signal to open, then the water will start flow; When you take your hand away, the sensor will indicate the solenoid valve to close, then water flow will stop.

The touchless faucet kitchen needs electricity for sure. Both the sensor and solenoid valve works need electricity power. Normally three choices: DC 6V: 4xAA alkaline batteries; AC: using a transformer to transfer power from 220V/380V to 6V; Both DC/AC models existed, firstly use AC power to work, if AC no power then DC start to work.

6V with 4xAA alkaline batteries shall last approximately 3000 times/month for one year.

1.Battery issue: battery no power or battery installed in the wrong direction.
2.Sensor issue: the waterproof cable issue or sensor got damage.
3.Solenoid valve issue: the filter in the valve blocked or the valve is damaged.
