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-K09, which is used for automatic basin taps.
Rajeyn sensor faucet control box RJY-K09 features.
* For automatic basin faucets
* B-A-S-F environmental friendly material
* Super energy saving solenoid valve drive technology, 2 pieces AAA alkaline batteries will last 15 months with 50 circles per day.
* Compact design with small size including solenoid valve, built-in waterproof battery pack.
* DC/AC power supply
The sensor faucet control box RJY-K09-2 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.
| Rating voltage | DC6V |
| Working voltage | DC4.5V-6.6V |
| Type | Normal closed pulse valve |
| Resistance | 15Ω±0.5Ω(20°C) |
| Pulse width | 20ms |
| Medium temperature | 1-75ºC |
| Response time | turn on≤1s; turn off≤1.5s |
| Working pressure | 0.05-0.8MPa |
| 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.
- DC3V powered by 4 pieces AAA alkaline batteries.
- AC110-220V powered by main power.
- 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.
2. Static power: ≤0.15mw (≤25uA)
3. The sensing range error: ±10% of the rated sensing range. Sensor distance adjustable by remote controller.
4. Max output current: 800mA
5. Low voltage alarm: Working voltage≤4.4±0.2, sensor indicator flashes to remind replacing batteries.
There are two optional sensor functions.
Function 1: Automatic on/off. You put your hands/water bottle on the sensor range, water automatically flows. You remove your hands/water bottle out of the sensor range, water automatically stops.
Function 2: Wave on/off. You wave the sensor, water automatically flows and you wave the sensor again, water automatically stops.
