1.1 iSIC Components
The enclosure that houses the NexSens iSIC PCB, wiring, and
battery is a durable NEMA 4X enclosure. It measures 12” x 8” x
7” (inches) and is constructed of heavy-duty fiberglass.
This enclosure is certified for both indoor and outdoor use.
Falling dirt, rain, sleet, snow, windblown dust, splashing water,
hose-directed water, and corrosion will not damage the
enclosure. In addition, the box will be undamaged by the
formation of ice on the enclosure.
A number of connectors are located externally on the iSIC enclosure
(2) Expansion plugs for half-inch conduit or gland fittings
Two gland fittings are supplied with each iSIC to allow cables to enter the
inside of the iSIC enclosure.
Additional gland fittings can be purchased in two packs as part #A75.

(1) Gortex enclosure vent
A vent made of Gortex material is installed on the outside of the
enclosure to allow air to pass and keep moisture out. This keeps the
enclosure pressure at equilibrium with the atmosphere.
Spare or additional vents can be purchased as part #A70.
