D56M Series Differential Pressure Switch
Precision Sensors
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.
Features
Intended for gaseous media
Environmentally sealed with optional hermetically sealed contacts
Proven diaphragm and leaf spring technology for high cycle life

A-C Series Altitude Switch
Precision Sensors
The A-C series is the most lightweight and low profile altitude switch in the Precision Sensors product line. The capsule based sensing element provides repeatable and precise absolute pressure threshold detection by sensing changes in the ambient air pressure compared to an evacuated capsule. The skeletal construction removes the need for bulky pressure fittings.
Typical uses include aircraft cabin air pressure monitoring.
For an environmentally sealed alternative, refer to the E-C series. For qualification information, please consult the sales or engineering departments.
Features
Intended for gaseous media
Low profile skeletal design
Ni-Span-C capsule provides superior setpoint stability over temperature
Custom configurations available upon request
