Sensing and Control Honeywell Inc. 11 West Spring Street Freeport, IL 61032 www.honeywell.com/sensing Limit and Enclosed Switches Weather-Sealed Explosion-Proof Switches FEATURES 1 Sealing - applicable portions of NEMA 1, 3, 4, 4X, 6, 6P, 7, 9, and 13 1 Watertight and dusttight for outdoor use 1 4-20 mA analog output available 1 UL Listed, file #E14274 1 Analog UL file #E68247 1 CSA Certified, file #LR57324 1 Rugged cast aluminum housing 1 Pretravel, overtravel, and actuating sequence can be field adjusted without tools (all basics individually) 1 Rotary types convert in seconds to clockwise, counterclockwise, or bothway operation 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. O-ring seals make the enclosure weatherproof but are outside of required flame paths so explosion proof requirements are maintained. NEMA standards: 1, 3, 4, 4X, 6, 6P, 7, 9 and 13. UL listed: Class I, Div. 1, Groups B (14CX, 16CX, 24CX, 26CX, 36CX, and 84CX only), C and D; and Class II, Div. 1, Groups E, F and G. CSA certified: Class I, Div. 1, Groups B (14CX, 16CX, 24CX, 26CX, 36CX and 84CX only), C and D; and Class II, Groups E, F and G. For rapid response – off the shelf service, all bold face listings are normally stocked items. Analog output: either resistive or 4-20 mA is available. Operating temperature range is – 25° to +85°C (–13° to 185°F). Limit/Enclosed ROTARY ACTUATED SWITCHES CX Series 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.

Basic switches operate nearly simultaneously in multiple switch devices. 2 Shafts of devices without shaft restoring force can be rotated through 360°. 1 Basic switches will be in operated mode through two 105° sections. Eight side mounting holes can be tapped 5/16N-18. Rollers are nylon. Non-sparking rollers must be used in hazardous locations.

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 so explosion-proof requirements are maintained. CX Series STAINLESS STEEL LEVER ACTUATORS These levers match the corrosion resistance of the 80CX housing. Non-sparking rollers must be used in hazardous locations.
