Product description

Contactless Resistive Liquid Level Sensor mini FS-IR42B-PC-PH2.0 is composed of M14 plastic housing and IC board.

When the liquid level of the test moves up and down, the amount of light entering the receiving tube changes, thereby changing the output voltage of the level switch.

Photoelectric level switches rely on two basic scientific principles: refraction and reflection. When the detected liquid level is in the presence of water, the light entering the probe changes due to the refraction of the water, thereby detecting the presence of water. Since the product has already been introduced to the market, it has made significant improvements and improvements.



Simple construction,reliable performance

The product can output stable and reliable switch control signal of"making","breaking"without any fault action,so its reliability is very high and antiinterference is strong.

Sturdy and durable,need not maintain

The product can be used for a long time after it being installed,Almost no maintenance and repairing problem would occur during its operation period.

Easy installation method,convenient adjustment method

The liquid level control scope can be adjusted at willwith the locating piece moving up and down.Only one screw is needed to secure the signal cable to finish installation.


The main products used in household appliances (such as: water machine, drinking fountains, drinking machine, humidifier, dehumidifier, electric water heaters, air conditioning equipment, home water direct drink system, etc.)
