Power Supply: +5V Working Current: 25μA Detectable Wall Thickness: 1 - 13mm Make a water-drinking reminder by attaching it to the surface of your cup The Non-Contact Liquid Level S witch can be triggered when the liquid level falls below the sensor attached to the outside surface of a non-metal container. Unlike traditional liquid level sensors, it does not need to be immersed into liquid. This way, liquid will not be contaminated and the life of the sensor will not be reduced fast because of the contact between the liquid and the sensor. The sensor is very sensitive and stable and the output current is up to 100mA which can directly drive a relay. You can use this switch to monitor the condition of your water machine or make a water-drinking reminder by attaching it to the surface of your cup. Show more
