Infrared sensor for auto toilet flush KEG-3600D

As the most important part, the work of the sensor is to forward the signals to the valve to turn on the toilet 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 of 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 of stainless steel, some may use cheaper plastic material.

People who are asking more:

Automatic toilet flusher uses infrared sensor technology that will flush automatically after leaving, the sensor detects and gives a pulse signal to the solenoid valve, when you leave, flush automatically. Microchip controls all the processes. For more details, please view our blog.

Auto toilet flushers need electricity for sure. Both the sensor and solenoid valve works need electricity power.
Normally three choices:
DC: 4xAA alkaline 6V batteries;
AC: use a transformer to transfer power from 220V/380V to 6V;
DC/AC:Both DC/AC models existed, firstly use AC power to work, if AC no power then DC start to work.

6V with 4xAA alkaline batteries shall last approximately 3000 times/month for 1.5 to 2 years.

Normally there is a manual button on top of the cistern. If the automatic flush and remote control functions fail, you can active the manual button.

Sorry that there is no push button to flush, this s a automatic sensor touchless urinal valve with two step flush: 3 sec pre-flush + 8 sec post flush. Avoid touch, more health and clean.

Thank you very much for your question. After the power is off, stand at the position where the infrared sensor needs to be sensed. After turning on the power again, stand at the position where you need to sense the distance for 1 minute, then you can re-establish the sensing position. The sensor defaults to 30cm-100cm.
