Pressure switch for liquids and gas Ex-DCM and Ex-DNM HONEYWELL / FEMA

Pressure switches Ex-DCM and Ex-DNM HONEYWELL / FEMA can be installed directly on the pressure line (pressure gauge connection) or on a flat surface with two 4mm Ø screws.
The maximum medium temperature at the pressure sensor must not exceed the permitted ambient temperature at the switching device. Higher medium temperatures are possible provided the above limit values for the switching device are ensured by suitable measures (e.g. siphon).

Parameter Value
Kind of pressure overpressure, relative
Pressure connection internal thread G¼, external thread G½
Electrical connection terminal connection M16x1,5
Protection class IP65
Housing material rugged housing of seawater resistant aluminium die casting GD Al Si 12.
Media temp. -15 ... 60°C
Media temp. limit Higher temperatures are possible, provided that the limit is safeguarded by suitable measures (e.g. water tube trap, see Accessories for Pressure Switches / Transmitters)
Ambient temperature -15 ... 60°C
Ambient temp. limit at temperatures below 0°C, ensure that no water condensation can arise in the sensor and in the switching device
Switch function/capacity SPDT Microswitch; capacity 2 A inductive, 3 A resistiv
