The D56M differential pressure switch provides high precision measurement across a wide range of low-differential pressure conditions in a package smaller than other units of comparable capability. The membrane senses changes between the “high” and “low” pressure inlets while offering excellent repeatability and high cycle life. Optional hermetically sealed contacts mean the D56M can be well suited when vapor ignition is a concern.

Typical uses include airflow control plenums.

For a similar switch with a higher resistance to shock and vibration, refer to the D16M

For qualification information, please consult the sales or engineering departments.
