2.0 SCOPE
The information contained within this manual covers
the EH66/EH66X Series environmental enclosure.
3.0 DESCRIPTION
The EH66 Series is an all-weather environmental enclosure for 2/3" and 1" cameras with a maximum camera/
lens size of 7" W x 7" H x 22" L (17.7 cm x 17.7 cm x
55.8 cm). Rugged all aluminum construction protects
the camera from adverse weather conditions. Built-in
sun visor shields the lens from direct sunlight, and a vent
cap allows heated air to escape from the interior. Removable lid with four secure latches provides convenient access. Camera is mounted on an adjustable rail/
sled. Two adjustable glands in the bottom of the enclosure permit easy cable entry.
The EH66X Series is the same as the EH66 Series
except the enclosures have extra length to accommo-

date intensified cameras. The EH66X Series will accept
a maximum camera/lens size of 7" W x 7" H x 30" L
(17.7 cm x 17.7 cm x 76.2 cm).
Models With The Letters “HB” in the suffix come
equipped with a factory installed filtered blower and
wired blanket heater with thermostat controls. The
heater activates when the internal temperature falls
below 40° F (4.44° C). It is electrically insulated from
the enclosure and provides 160 watts of heat. The
blower provides 105 CFM and activates when the
internal temperature reaches approximately 100° F
(37.78° C). Internal temperature is reduced when the
blower draws ambient air from a filtered intake port,
circulates it through the enclosure, and exhausts it out
the vent cap.
Models With The Letter “L” in the suffix include
tamper resistant locks which are keyed alike.
