RJY-FDC Auto Tap Distance Sensor

RJY-FDC Auto Tap Distance Sensor
Product Detailed
1.Manufacturer 2.Remote controlled adjusting flushing duration & sensing range 3.Water saving 4.Low power consumption

Distance Measurement Infrared Sensor Module

Operating principle:

This infrared sensor module adds a signal processing component and optical lens respectively in the emitter and receiver. The infrared-emittingdiode sends an infrared beam in a certain angle and the beam reflects back when it meets the detected object. The distance between the object and the sensor module can be calculated with triangulation measurement principle.

Adopting triangulation measurement principle, the detected object’s meterial, color, size as well as the testing evironment temperature and light will not influence the testing accuracy, which avoids traditional sensor disadvantages. This infrared sensor module is suitable for all kinds of sensor faucets, sensor urinal flush, sensor toilet flush and sensor shower.

 Features of infrared auto sensor faucet, urinal flusher, toilet flusher etc.

Our Advantages

1. The same control panel/circuit board can be used for faucet, urinal flusher, toilet flusher and shower due to different settings.

2. Sensor has features such high integration, stable performance and reliable quality by adopting automatic SMT.                                                                                  

3. Low power consumption (Operation Consumption is <60uA and Overall Power Consumption is <0.5W. 6V alkaline batteries can be used for 1-1.5years).                                               

4.With special seal processing, the sensors have strong moistureproof function.

5. High anti-interference and anti-vibration performance.                                                                                   

6. Sensing range and flush duration can be adjusted by remote controller.
