2SE Klixon® Solid–State Vane Switch
•Commercial or military grades
•Variety of switching modes
The Klixon 2SE solid–state vane switch has advanced, state-of-the-art airflow sensing. Successor to electromechanical vane types, the 2SE is designed to sense and protect against the loss of airflow in power supplies, data processing units, or any other commercial or military electronic equipment where it is necessary to recognize the loss or reduction of airflow.

Temperature vs. Velocity Curve
Note: The gray region is the deadband, in which sensor could be in either the fault or the no–fault condition. Number on curve is for building part number of device.
Below is the typical 2SE configuration, but others are available. Drawing is for reference only.
