Spout Mounted Sensor Faucet KEG-8110AD

Touchless Faucet with sensor in mouth spout

The spout mounted sensor faucet KEG-8110AD uses active infrared sensor technology that allows starting the flow of water without touching the faucet. The sensor is spout mounted and just wave the hand in front of the spout to start the water, wave again water stop. It is easy to install with a single hole deck mounted on the basin. It’s a commercial touchless faucet that can be widely used in public restrooms or home bathrooms.

How does the spout mounted sensor faucet work?

The spout mounted touchless faucet has a sensor near the spout that can adjust the sensor distance automatically based on different working conditions.

When people put their hands near the faucet spout, the water starts automatically. When your hands leave, the water stops. Or waiting after the setting minutes, normally 60 seconds and the water stops.

  • It is controlled by a single-chip microcomputer and has the function of 1-minute timeout to stop water supply, so as to avoid waste of water resources caused by foreign matters in the sensing range for a long time.
  • Water-saving: Water-efficient faucet reduces overall water usage without sacrificing water.
  •  Automatically adjusting the sensing distance.
  • Energy-saving: 4AA alkaline batteries shall last approximately 3000 times/month for one year.
  • Easy installation and cleaning.
  • Outside connected battery box for a convenient changing between AC,DC and AD.
  • Healthy and Safe: with the touch-free faucet, it can prevent the spread of bacteria and germs. It’s not only time-saving but also hygienic.

Spare parts

The spare parts include the control box and AC power adapter. In the control box, it has the solenoid valve and DC battery box. With the connector, it connects with the faucet body.

Infrared sensor for touchless spout faucet

As the most important part, the work of the sensor is to forward the signals to the valve to turn on the faucet after detecting your hand. Its job is to inform the valve when to start or stop the flow based on the presence or absence of your hands.

The sensor for spout mouth commercial touchless faucet is a smart design sensor. It can be assembled well inside the faucet just near the spout. The sensor distance and flushing time can be adjusted by a remote controller.

Sensor life circle reaches 500,000 times and DC batteries alkaline batteries life circle is about 60,000

Normally the material of the sensor cover is plastic ABS or PA, the infrared beams can pass through it. Kege have about 50 types of different sensor head for the selection. We can also customize the sensor cover according to your products.

Low power indicator

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 Automatically Adjusted

Sensor distance is automatically adjusted according to working conditions and environment.

Battery and Main Power Supply

  • Power supply: DC6V/AC110-240V
  • The valve will automatically stop water flowing if no power is supplied.

Battery replacement

When the indicator light continuously and slowly double flashes the alarm, please replace the battery.

  1. Remove the battery case cover.
  2. Replace with 4 AA alkaline batteries.
  • Make sure the batteries are installed correctly (positive and negative charge).
  • Do NOT mix new old batteries.
  • Do NOT mix batteries of different brands.
