1 Rotary types convert in seconds to

clockwise, counterclockwise, or both- way operation CX switches are built especially for outdoor use in hazardous atmospheres. These en- closures 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 temper- ature of the surrounding gas. O-ring seals make the enclosure weather- proof but are outside of required flame paths so explosion proof requirements are main- tained. Analog output: either resistive or 4-20 mA is available. Operating temperature range is –25 ° to 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.

They comply with the NEMA 4X requirement for protec- tion 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 require- ments are maintained.

MODIFIED SHAFT ENABLES DIRECT COUPLING CX switches are available with a 3⁄8 inch diameter by 3⁄4 inch long flatted shaft which conforms to standard NEMA motor shaft specifications. It accepts commercially available shaft couplers, permitting easy, direct coupling to most equipment actua- tors. To specify a ‘‘direct-couple’’ CX switch, add -DO1 to catalog listings shown in the order guides, i.e. 11CX12-DO1. Pricing is the same as for unmodified versions.
