A touch sensor automatic kitchen faucet uses capacitive touch control technology that allows you to start the flow of water by touching any part of the faucet. You just touch the faucet body in any part, then the water flow, touch again water stop.

Kege can offer the whole solution, capacitive sensor circuit electronic design, control box and power supply design.


  • Touch sensor: Keeping the faucet handle on, touch the faucet body, water flows; touch again, water stops. Water stops automatically after 3mins’ continuous flow.
  • Water-saving: Water-efficient faucet reduces overall water usage without sacrificing water.
  • With the emergency button, turn on/off water flow by the manual handle when power-off or function failure.
  • 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.
  • With the self-study function, we will adjust the touch sensitivity automatically according to the environment.

Capacitive sensor Technology

The capacitive sensor detects the electrical capacity of people and objects. It is therefore sensitive to their presence or movement. It is adapted to short-range detection (5cm) or contact. Our sensors are customizable and guarantee excellent detection stability.

Touch kitchen faucets use capacitive sensor technology that allows you to start the flow of water by touching the faucet’s body. Instead, just touch any part of your kitchen faucets, the sensor will give the solenoid valve a signal to open, then the water will start flow; When you take your hand off the faucet, the sensor will indicate the solenoid valve to close, then water flow will stop.

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

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