MICRO SWITCH™ Weather-Sealed, Explosion-Proof Switches CX Series Datasheet 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 COST OPTIMIZATION RELIABILITY • GLOBALLY ACCEPTED 2 sensing.honeywell.com 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. sensing.honeywell.com 3 Potential Applications INDUSTRIAL • Seaside grain and fuel loading docks that may require explosion proof and corrosion resistant switches • Oil and gas wells, refineries, and fuel storage facilities that may require explosion proof and corrosion resistant switches • Chemical plants with corrosive environments  0518 Table 1.

It accepts commercially available shaft couplers, permitting easy, direct coupling to most equipment actuators. To specify a ‘‘direct-couple’’ CX switch: Add-DO1 to catalog listings shown in the order guides, i.e. 11CX12-DO1. Mounting Holes Add the letter A to listings with side mounting holes tapped 5/16-18(8). Example: 11CX2A Add the letter B to listings with thru mounting holes tapped 3/8-24(4). Example: 11CX2B. CX Series Replacement Basic Switch Assemblies These assemblies are factory-adjusted to the same operating characteristics as a new CX switch. They include components subject to mechanical or electrical wear: basic switches, cams, cam followers, and springs. To order, change the first number in the complete switch catalog listing to 9 for rotary switches. For example: Rotary switch 11CX2 Replacement = 91CX2 Note: Basic switch assemblies for rotary actuated switches, with or without spring return, will be the same. For example: 11CX2 and 11CX12 use 91CX2.
