Bronze housing for use in corrosive
environments

80CX switches have rugged bronze housings which are 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. O-ring seals make the enclosure weather-
proof, but are outside of required flame paths, maintaining explosion-proof
requirements.

Operating characteristics

Notes:
Add the letter “A” to listings with side mounting holes tapped 5/16 (8).
Example: 11CX2A

Add the letter “B” to listings with thru mounting holes tapped 3/8-24 (4).
Example: 11CX2B

Add the letter “C” to listings for low temperature (-40 °C/°F) applications.
Example: 11CX2C

Add “D01” to specify a “direct-couple” listing with 3/8 in. dia by 3/4 in. long
flatted shaft.
Example: 11CX2-D01

Add the letter “E” to listings for European Atex approvals.
Example: 11CX2E

For Replacement Basic Switch Assemblies, change the first number in the
listing to “9”.
Example: 11CX2 becomes 91CX2
