Limit and Enclosed Switches
CX Series
Weather-Sealed Explosion-Proof Switches
FEATURES
ɀ Sealing - applicable portions of NEMA 1,
3, 4, 4X, 6, 6P, 7, 9, and 13
CX switches are built especially for outdoor NEMA standards: 1, 3, 4, 4X, 6, 6P, 7, 9 and
use in hazardous atmospheres. These en- 13.
closures are constructed to withstand the UL listed: Class I, Div. 1, Groups B (14CX,
pressure of an internal explosion. Flame 16CX, 24CX, 26CX, 36CX, and84CXonly), C
paths cool the exploded gases to a point and D; and Class II, Div. 1, Groups E, F and

ɀ CSA Certified, file #LR57324
ɀ Rugged cast aluminum housing
ɀ Pretravel, overtravel, and actuating
sequence can be field adjusted without
tools (all basics individually)
O-ring seals make the enclosure weather-
proofbutareoutsideofrequiredflamepaths
so explosion proof requirements are main-
tained.
For rapid response – off the shelf service,
all bold face listings are normally stocked
items.
ɀ Rotary types convert in seconds to
clockwise, counterclockwise, or both-
way operation
Analog output: either resistive or 4-20 mA is
available.
Operating temperature range is –25° to
+85°C (–13° to 185°F).
ROTARY ACTUATED SWITCHES
ORDER GUIDE
As factory assembled, all basic switches
operateonclockwiseandcounterclockwise
rotation. Actuating mechanism can be field
adjusted for CW or CCW operation only. No
tools are required.
