PCFS-IR2125A level sensor contact type, it is used for tube. The principle is infrared, output signal is analog. When there is no water, the sensor outputs low voltage value; When there is water, the sensor outputs a high voltage signal. The size can be customized. The photoelectric liquid level switch has high precision, low price, high reliability and wide application environment, it is less affected by strong acid, alkali and viscosity. Photoelectric level sensors can be used for higher liquid level accuracy requirements.
As per PN and Model Standard lot size
