Motion sensor for Automatic Urinal Flusher

As the most important part, the work of the sensor is to forward the signals to the valve to turn on the urinal flusher after detecting your body. Its job is to inform the valve when to turn on or off the water when your body comes and leaves. The cover of the sensor is made by plastic ABS or PA and there is an electronic circuit board inside the sensor eye which also includes the led light.

Normally the sensor eye is placed on the metal faceplate. Mostly the plate is made by stainless steel, some may using cheaper plastic material.

Infrared Sensor Head Optional

How to install automatic urinal flush?


Dig a suitable hole on the wall according to the installation instruction. Inter control box into the wall and connect the inlet pipe and outlet pipe. Open the stop-valve to ensure all the connectors are watertight.

The distance between the housing surface and the ceramic tiles should be longer than 15mm.

Auto urinal valve installation step1


Adjust the position of the control box, fixed with pieces of wood or other fillers. Then cover the control box by protecting board to avoid the solenoid valve be damaged when filling the cement around the control box. Finally, laying the tiles.

The protecting board should be taken down when finished.

People who are asking more:

Automatic urinal flusher uses infrared sensor technology that when you stand in front of urinal ceramic, the sensor detects and gives a pulse signal to the solenoid valve to open and give 2s pre-flush, then stop. After you leave, again 6s flush automatically. Program control all the process.

Auto urinal flushers need electricity for sure. Both the sensor and solenoid valve works need electricity power. Normally DC: 4xAA alkaline 6V batteries.

6V with 4xAA alkaline batteries shall last approximately 3000 times/month for one year.

You can activate a flush by holding the palm of your hand up to the sensor for a few seconds before taking it away.
