Automatic Sensor Faucet Control Module RJY-K06

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 the most classic model RJY-K06, which is used for automatic basin taps.

The sensor faucet control box RJY-K06 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 and transformers are compact designed into the gray control box.

# Solenoid Valve Model NO.: RJY-FD08A-3

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: 17Ω±0.5Ω(20°C)
5. Pulse width: 35ms
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. DC6V powered by 4 pieces AA alkaline batteries.
2. AC220V powered by main power.
3. Both DC6V and AC220V. The battery is stand-by. If the main power AC220V 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.
