4 Identification
4.1 Product description and type
designation
The NXM housing, entirely constructed from AISI 316
electropolished stainless steel, is designed to operate
in special environments such as marine, industrial,
chemical and where the external conditions are
highly corrosive.
The NXM housing consists of a 130mm diameter
cylindrical body enclosed by two 9mm thick circular
flanges. The back flange is equipped with two
PG13.5 cable glands for external connections. The
housing can be equipped with a flange designed to
create an air barrier in front of the glass to prevent
the formation of dust deposits. With the optional
air barrier, the filter group is recommended, which
purifies the air drawn from a compressor.
A wide range of accessories is available: heater,
camera power supply, stainless steel special bracket,
and the possibility of mounting the wiper and
washer.
The housing can be equipped with a double heater
for temperatures down to -40°C (-40°F).
