Waterproof Auto Infrared Sensor Circuit for Sensor Faucet with Wire and Jack

Active infrared touchless sensors use the emission and reception of infrared beams to detect the presence and/or movement of objects or people in their field of detection. The technology is ideal for applications requiring a long and narrow detection range.

The active infrared proximity sensor is widely used because of its low cost, small size and low power consumption. Our active infrared detection module can work reliably in 10000LUX light environment, pass 4KV/5khz group pulse experiment and pass EMC certification. When the temperature changes from 5ºC to 60ºC, the induction sensor distance changes by less than 8%.

* A variety of sizes and shapes are available for most applications.
* Low power consumption, with an average static current of less than 30UA (or less than 10UA in some cases). It is suitable for various battery-powered applications.
* The sensor distance can be adjusted from 5 mm to 1500mm (30cm x 30cm standard whiteboard as reference). Sensor distance can be customized.
* Various sensor distance adjustment methods: by remote controller, automatically adjust the induction distance by human intervention on power-on, and automatically adjust the induction distance according to the environment.
* Multiple outputs are available: high/low level output, pulse output, and serial port output.
* Multiple supply voltages: 3V, 6V, 12V, and 24V are available
* Output current reaches 800ma, which can directly drive relays, solenoid valves and motors etc.
* Tailor-made infrared induction control modules are available.

The sensor eye SLC-00007 is widely used for automatic commercial sensor basin faucets, touchfree kitchen faucets, wave on/off sensor water taps, medical places touchfree faucets, automatic water dispenser/fountains. There are two optional sensor functions.

Function 1: Automatic on/off. This is the regular function for touchfree basin faucets and water dispenser/fountains. 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. The water will automatically stop flowing if continuously flowing for 60 seconds (We call this function security stop timing and this timing can be customized).

 This function is good for touchless kitchen faucets and water dispenser/fountains. You wave the sensor, water automatically flows and you wave the sensor again, water automatically stops. This function also includes security stop timing and this timing can be customized, too like automatic sensor.

Rajeyn Sensor Features and Applications

• Used for commercial and household touchless faucets/water dispensers etc.
• Adjustable sensor range and flushing time by a remote controller.
• Auto-save parameters if power failure.
• Low power consumption. 4AA alkaline batteries lasts about 2 years.
• Glue potting with strong moisture-proof function.
• High anti-interference and anti-vibration performance.
• We have more than 50 different sensor eyes and electrical wires for your selection.
• The automatic valve closing function of AC power-off can be widely used in intelligent bathroom products.

There are over 50 different sensor housings to suit different design PCBAs. They are variety of designs for all-in-one type and separated PCBA. Shapes including round, rectangle, semicircular etc. The sensor functions and wire connections can be tailor-made based on customers need. 


Besides sensor cases, we have variety of waterproof wire connections. The most popular types are 4-pin waterproof wire connecting with control box for sensor taps and 2-pin as well as DC type waterproof wires for sensor urinal and sensor toilets. Below are some potting sensors with different sensor cases, PCBA and wires. We are capable of providing tailor-made infrared sensors for your automatic systems.
