People of all ages, including children and the old, can easily use touchless  sensor faucets. To operate the flow of water, all you need to do is wave your hand in front of the sensor, and it turns off automatically when you’ve finished. You can place your cup under the faucet or wave your hand over the top to activate the sensor. Touchless faucets are available in various design options, and since they rarely leak, they tend to be low maintenance. Generally common designs are deck-mounted and wall-mounted types. Rajey’s durable zinc-alloy wall-mounted sensor tap is quite popular in market. Even though it’s made of zinc-alloy yet the water does not go through the faucet body. Instead, there’s a water hose directly go through faucet body to the water spout. This is quite safe to use daily.

This faucet includes THREE parts.

PART 1: Infrared sensor. The sensor sends the signal of motion to the valve to activate the faucet. It lets the valve know when it’s time to start or stop the water based on the presence or absence of movement. The sensor will use infrared light to detect movement. Infrared sensors are often at the base or lip of the spout, so they can easily detect motion without obstruction from large items. As explained, RJY-11-Z102AD sensor eye is nearby the spout (lip of the spout).

PART 2: Solenoid valve (control box).

The signals of movement from the sensor engage the solenoid valve. The signal’s polarity affects whether the solenoid engages a push or pull action. The valve engages the flow of water through a rubber-like disc.

When the sensor doesn’t detect a signal, the valve remains closed so no water will flow through the faucet. However, as the sensor detects motion, it sends a positive message to the solenoid, which pulls the valve open and allows water to come out. The solenoid closes the valve with its push action once you move your hand away. Rajeyn’s solenoid valve is usually integrated into a control box, which is something like a hub to connect sensor, valve and power. RJY-11-Z102AD includes a compact small black control box that easy to install and fix (see below picture).

PART 3: Power source. Touchless faucets require electricity to operate, whether through using batteries or by connecting to an electrical socket in the wall depending on your choice. Check the packaging of your touchless system before you order it to ensure you have the proper power source for it. A battery-powered faucet keeps the solenoid valve in the open position until a power flow pushes it shut. A transformer-powered faucet has a continuous electric current that keeps the solenoid valve open. RJY-11-Z102AD includes both battery box and AC power source to ensure that the touchless system will work at any circumstances.
