Sensor Faucet Control Box By Fuzhou Rajeyn Electronic Sci-tec., Ltd.

These Sensor Faucet Control Box (included in most sensor tap package like RJY-6110AD, RJY-6150AD) is a square box that sits or mounted underneath the sink as part of a typical sensor electronic faucet installation process. Most of our sensor faucets ranges come with a control box, except our 2-IN-1series range.
The Sensor Faucet Control Box is like a hub which enables water to flow IN (from main water supply) and OUT (to sensor faucet). When you open up a control box, you will find a solenoid valve, battery case/transformer and infrared signal wire connection.
Following components are included in the control box
1) Solenoid valve
A solenoid valve is a device that allows or restricts water from passing through it. It has a built-in magnetic latch that opens and closes whenever an electric signal is sent or received from the infrared sensor.
2) Battery Case
The battery case holds 4 AA alkaline batteries, which means DC 6V voltage. The battery can be used in conjunction with the Main power supply. For example, if the power goes, the DC battery power will automatically take over.The battery should last upto 1.5 years on an average usage of 20,000 cycles per month (Av. 600 cycles a day). Or therea s a transformer.
3) Wires for Connection
There are wires connecting power supply and sensor as well as solenoid and sensor. The sensor cable is connected to the solenoid valve and to the power supply to get necessary current needed for activation.
