This sensor basin mixer is a user-friendly compact tap with a sensor. The washbasin tap has no levers or handles. It switches on through the infrared sensor without any contact. It is activated by a simple hand movement in front of the sensor. The infrared sensor works on AA LR6 1,5 V batteries. The batteries are not included. Each bathroom tap features a low-noise, replaceable ceramic disc cartridge. Additionally, the solid metal construction in the chromed finish makes this sink tap highly durable. The delivery includes necessary metal connection hoses, making the base-mount faucet easy to install.
