Touchless faucets are also called automatic faucets, sensor faucets, sensor taps. Touchless faucets are widely used in our life. You can see them everywhere in the public washrooms. Such as in the shopping malls, restaurants, hotels, cinemas, airports, train stations and so on. The reason why touchless faucets are so widely used is that they are so convenient to use. They don’t allow to touch the faucet body. They are kind to the patient, kids, and the old.
Touchless faucets are hygienic and germs free because they are totally touch free. It can avoid viruses or germs spreading in the kitchen, bathrooms, washrooms, and so on.
DO TOUCHLESS FAUCETS NEED ELECTRICITY?
Since touchless faucets have so many functions, people are always asking this question. The answer is definitely yes.
Touchless faucets need electricity because it’s key spare parts, the motion sensors, the solenoid valves all need electricity to work. The KEGE touchless faucets are in a low power consumption design. Below we will introduce simply how touchless faucets work.
- There are always two LEDs in the motion sensor which we call infrared LED. One LED emits infrared beams, another receives infrared beams. When people come near the sensor, the infrared beams from the emitted LED to reflect the receiver LED. It gives a signal to the motion sensor control IC and it delivers the signal to the solenoid valve. It needs electricity to keep the LED, IC, and control board working.
- The solenoid valve which we also call them electromagnetic valve. When it receive the signal from the IC or sensor, it controls the water open and close.
Electricity power type used in touchless faucets
After the above introduction, we know touchless faucets need electricity. There are several electricity power supply types used in touchless faucets. The electricity power supply is connected with waterproof cables to the motion sensor, solenoid valves, and so on.
AC ADAPTER TYPE
AC is used to refer to an electric current that continually changes direction as it flows. AC is an abbreviation for ‘alternating current’.
For AC type touchless faucet, it is using AC power. It has an AC adapter, one side with a power plug and one side with a waterproof connector connected with the sensor or control box. The input can be 110v-380v and output 6V-9V. Inside the AC adapter, it is a small transformer. The ac adapter is not expensive and can buy it separately.
DC BATTERY TYPE
DC is used to refer to an electric current that always flows in the same direction. DC is an abbreviation for ‘direct current’.
For DC type touchless faucet, it is using DC power with batteries. It is also called battery sensor faucet, battery operated touchless faucet,battery powered sensor faucet and battery operated automatic faucet.
The battery operated touchless faucet has a battery holder. Inside the battery holder, there are always 4xAA alkaline batteries in 6V. It gives the electricity power to the sensors and solenoid valve working.
Batteries shall last approximately 3000 times/month for one year at least. Battery replacement is easy, just open the battery box cover and put the new alkaline batteries into the box. Notice: please take care of the battery polarity.
Normally the DC type touchless faucets are a little cheaper than the AC type touchless faucets.
How Long Do Batteries Last In A Touchless Faucet?
The lifespan of the batteries in a touchless faucet is dependent on the size and type of battery the faucet requires. It also depends on how often the touchless faucet is used. However, touchless faucet batteries typically last about one to two years on average, based on approximately 3000 times/month.
