• Thread G1/2, IP66/68 NEMA TYPE 4X/6P
If the G1/2 thread is selected, the device is delivered with an M20 thread as standard and a G1/2
adapter is included with the delivery, along with the corresponding documentation
• Thread NPT1/2, IP66/68 NEMA TYPE 4X/6P
• M12 plug
• When housing is closed and connecting cable is plugged in: IP66/67 NEMA TYPE 4X
• When housing is open or connecting cable is not plugged in: IP20, NEMA TYPE 1
NOTICE
M12 plug: Loss of IP protection class due to incorrect installation!
‣
The degree of protection only applies if the connecting cable used is plugged in and screwed
tight.
‣
The degree of protection only applies if the connecting cable used is specified according to
IP66/67 NEMA 4X.
‣
The protection classes are only maintained if the dummy cap is used or the cable is connected.

WARNING
The maximum pressure for the device depends on the lowest-rated component with regard to
pressure (components are: process connection, optional mounted parts or accessories).
‣
Only operate the device within the specified limits for the components!
‣
MWP (Maximum Working Pressure): The MWP is specified on the nameplate. This value refers
to a reference temperature of +20 °C (+68 °F) and may be applied to the device for an unlimited
time. Note temperature dependence of MWP. For flanges, refer to the following standards for
the permitted pressure values at higher temperatures: EN 1092-1 (with regard to their stability/
temperature property, the materials 1.4435 and 1.4404 are grouped together under EN 1092-1;
the chemical composition of the two materials can be identical), ASME B16.5, JIS B2220 (the
latest version of the standard applies in each case). MWP data that deviate from this are
provided in the relevant sections of the Technical Information.
‣
The Pressure Equipment Directive (2014/68/EU) uses the abbreviation PS . This corresponds to
the maximum working pressure (MWP) of the device.
The following tables show the dependencies between the seal material, process temperature (T

and process pressure range for each process connection that can be selected for the antenna used.
