Touchless Water Faucet Control Box RJY-K07-1

What’s the faucet control box/control module?

A sensor faucet control box is a square box that sits or mounted underneath the sink as part of a typical sensor faucet installation process. The control box is like a hub which enables water to flow IN (from main water supply) and OUT (to sensor faucet). Most of Rajeyn sensor faucets come with a control box, except 2-IN-1 series such as RJY-11-B201D and RJY-11-B204D. Rajeyn has various control boxes for both basin and kitchen faucets and this page introduces model RJY-K07-1, which is used for touchless basin water taps.

The sensor faucet control box RJY-K07-1 includes a solenoid valve, battery case and/or transformer (adapter) and infrared signal wire connection as well as infrared sensor. All the wires connected to each part are waterproof. The battery pack is built-in design and easy to take out batteries.

# Solenoid Valve 

The solenoid valve has a built-in magnetic latching valve that opens and closes whenever an electric signal is sent or received from the infrared sensor. The valve water inlet and outlet size is G1/2”. Valve body is made of plastic while two water connectors are made of brass. The solenoid valve life circle is up to 500,000 on/off. Technical parameters as below.

1. Rating voltage: DC6V
2. Working voltage: DC4.5V-6.6V
3. Type: Pulse valve
4. Resistance: 15Ω±0.5Ω(20°C)
5. Pulse width: 20ms
6. Medium temperature: 1-75℃
7. Response time: turn on≤1s; turn off≤1.5s
8. Working pressure: 0.05-0.8MPa
9. Thread size: G1/2”

# Power Source (battery pack and/or transformer)

There are three options for power source. For the power adapters, there are optional power plugs for markets from USA, UK, EU and Australia etc.

1. DC3V powered by 4 pieces AAA alkaline batteries.
2. AC110-220V powered by main power.
3. Both DC3V and AC220V. The battery is stand-by. If the main power AC110-220V is off, the batteries will automatically switched on. This way makes sure the product will 100% work even though there’s no main power.

# Infrared Sensor 

There are over 50 different sensor housings for infrared sensors. They are variety of designs for all-in-one type and separated PCBA. Shapes including round, rectangle, semicircular etc. The sensor function can be tailor-made based on customer’s need.

1. Power supply: DC 4.3～6.4V
2. Static power: ≤0.15mw (≤25uA)
3. Default sensing range: 280mm. Adjustable sensing range: 180mm-380mm (reference: 29.7cm*29.7cm white board). The sensing range error: ±10% of the rated sensing range. Sensor distance adjustable by remote
controller.
4. Max output current: 800mA; Output voltage: 3.9V-6V; Output pulse width: 35ms.
5. Low voltage alarm: Working voltage≤4.4±0.2, sensor indicator flashes to remind replacing batteries.
6. Sensing range stability: Sensing range rangeability is ±5﹪ if working voltage decreases from DC6.4V to DC4.3V; Sensing range rangeability is ±15﹪ if temperature increases from 0℃ to +45℃.
7. Anti-interference performance:
1） There’s no malfunction if more than one systems working together at the same time.
2） There’s no malfunction if there are commonly used electrical appliances nearby.
3） Sensing range rangeability is ±10﹪ with filament lamp slants beyond 1 meter.
8. Shock resistance: hit or beat is not allowed.
9. Direct strong light should be avoided.
