Limit and Enclosed Switches
Weather-Sealed Explosion-Proof Switches
FEATURES
Sealing - applicable portions of NEMA 1,
3, 4, 4X, 6, 6P, 7, 9, and 13
Watertight and dusttight for outdoor use
4-20 mA analog output available
UL Listed, file #E14274
Analog UL file #E68247
CSA Certified, file #LR57324
Rugged cast aluminum housing
Pretravel, overtravel, and actuating
sequence can be field adjusted without
tools (all basics individually)
Rotary types convert in seconds to
clockwise, counterclockwise, or both-
way operation
CX switches are built especially for outdoor
use in hazardous atmospheres. These en-
closures are constructed to withstand the
pressure of an internal explosion. Flame
paths cool the exploded gases to a point
less than the lowest safe operating temper-
ature of the surrounding gas.
O-ring seals make the enclosure weather-
proof but are outside of required flame paths
so explosion proof requirements are main-
tained.
Analog output: either resistive or 4-20 mA is
available.
Operating temperature range is – 25° to
+85°C
(–13° to 185°F).
ORDER GUIDE
As factory assembled, all basic switches
operate on clockwise and counterclockwise
rotation. Actuating mechanism can be field
adjusted for CW or CCW operation only. No
tools are required.
