MICRO SWITCH™ CX Series
Weather-Sealed, Explosion-Proof Switches
MICRO SWITCH™ CX switches are built especially for outdoor use in hazardous atmospheres. These enclosures 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 temperature of the surrounding gas.
MICRO SWITCH™ 80CX Series switches have rugged bronze housings that are designed to be resistant to salt
water and other corrosive environments. They comply with the NEMA 4X requirement for protection against corrosion,
in addition to NEMA enclosure standards met by other CX switches.
The product’s o-ring seals make the enclosure rain tight, but are outside of required flame paths so explosion proof
requirements are maintained. Unless special ordered, all basic switches operate on clockwise and counterclockwise
rotation. The actuating mechanism can be field adjusted for CW or CCW operation only. No tools are required.
What makes our switches better?
Building block design allows for digital switching outputs, or 4 mA
to 20 mA analog output, or digital switching outputs with a 4 mA
to 20 mA analog output
Weather sealed to NEMA and IP ratings
UL, CSA, ATEX, IEC Ex, INMETRO certified for hazardous
(explosive) environments
Designed with the end user in mind, these switches help to create
user-friendly interfaces with broad application possibilities to help
meet the challenges of many different environments
Available with gold contacts, low-temp seals, and
bronze corrosion-resistant housing

Features
and Benefits
WELL-SUITED FOR EXPLOSIVE ENVIRONMENTS
MICRO SWITCH™ CX Series switches are certified for applicable portions of
NEMA 7 and 9
for hazardous locations (explosive environments). Select CX
switches are certified to ATEX, IEC Ex, and INMETRO specifications for global
applications.
Available with digital or analog outputs
WATERTIGHT AND DUST-TIGHT FOR OUTDOOR USE
Due to its engineering design and sealing (NEMA 1, 3, 4, 4X, 6, 6P, and 13), the
MICRO SWITCH™ CX Series is rated for
rain, wind, snow, ice, and blowing
dust environments.
CORROSION RESISTANT
Bronze housing material is available on 80CX Series catalog listings.
4 MA TO 20 MA ANALOG OUTPUT AVAILABLE
Allows for use in accurate positioning applications, such as those found on seaside
grain and fuel-loading docks, oil and gas wells, refineries, chemical plants, and
more.
MEETS HAZARDOUS AREA REQUIREMENTS
UL Listed, file #E14274, Analog UL file #E68247, CSA Certified, file #LR57324,
ATEX certificate KEMA 01ATEX2111 X, IEC Ex certificate IEC Ex TSA 06.003X, and
INMETRO certificate TUV 14.0553.
OPTIONAL HOUSING CHOICES
CX Series switches offer a
choice of rugged cast aluminum or bronze
housings.
Both housings withstand harsh environments, and bronze is available
for use in corrosive environments.
UNIQUE DESIGN FEATURES
Featuring
field-adjustability,
the CX Series allows pretravel, overtravel, and
actuating sequence to be field adjusted without tools (all basics can be adjusted
individually). Rotary types convert in seconds to clockwise, counterclockwise,
or both-way operation. These features
may help to reduce set up time
while
allowing for quick and easy changes to switch operation.
