MICRO SWITCH™ Hazardous Location Switches Line Guide - Honeywell Sensing and Control - #1

Text version of the page

Hazardous environments demand Honeywell. When conditions are hazardous and performance is critical, Honeywell Sensing and Control (S&C) delivers exceptional performance. Our hazardous location switches are limit switches designed specifically for dangerous indoor or outdoor locations — where reliability and repeatability are essential. To comply with explosion-proof requirements, the flame path within the switch housing is designed to contain and cool escaping hot gases FEATURES HAZARDOUS LOCATION LIMIT SWITCHES EX Series. Features: Smallest UL-listed housings available for use in hazardous locations • ATEX and IEC Ex certified • Up to 20 amp capacity • Ample wiring space • Mounts from four sides • Roller arms adjustable through 360 degrees • Non-sparking actuators • Captive cover screws • Grounding screw Benefits: Flame paths within the housing cool exploding gases below the kindling temperature before they reach the explosive gases surrounding the housing. Potential applications include control valves and actuators, petrochemical plants, conveyors and material handling. BX Series. Features: UL, CSA, ATEX, and IEC Ex certified • Sealing - NEMA 1, 3, 4, 6, 13 • Diverse conduit selection for wide range of potential applications • Tracking interchangeability with MICRO SWITCH™ HDLS • Variety of heads and non-sparking actuators • 10 A continuous carry electrical rating • Choice of silver or gold contacts • Internal grounding screw MICRO SWITCH™ Hazardous Location Switches Line Guide continued on page 4 Benefits: BX enclosure sealed for protection against corrosion, water, dust and oil as defined in NEMA 1, 3, 4, 6, 13 and IP67 as defined in IEC 60529. These enclosures are certified for II 2 GD; Ex d IIC T6; Ex d tD A21 T85°C. The entire series BX complies with the ATEX Directive and is IECEx certified. BX with conduit types 1/2-14NPT, 3/4-14NPT also meet the North American Hazardous Locations Designation: Class I, Groups B, C and D; Class II, Groups E, F and G and comply with UL Standard: UL 894, CSA Standard: C22.2 No. 25-1966, C22.2 No. 30-M1986. For outdoor use or in adverse environments where a combination of explosion proof plus sealing requirements are needed. To comply with explosion proof requirements, the BX has flame paths within the housing, which cool exploding gases below the ignition temperature before they reach explosive gases surrounding the housing. Flame paths are (1) an extended plunger between the switch cavity and head and (2) the cover-housing threads on the front of the switch. Potential applications include control valves and actuators, petrochemical plants, waste treatment, hazardous waste handling, paint booths, mining equipment, pulp and paper coating, grain elevators, and more. CLSX Series. Features: Positive-opening operation of normally closed contacts • Available with up to 2NC positive-opening contacts • Cable length may be up to 200 ft in a straight line • Maintained version has broken/slacked cable detection • Tension indicator mark for easy adjustment • For use either indoors or outdoors • Sealing meets NEMA 1, 3, 4, 13 • Internal grounding screw • UL/CSA approvals — fumes that otherwise could cause an explosion outside the switch. Honeywell S&C hazardous location switches are found in applications as diverse as grain elevators, offshore drilling, petrochemical and waste treatment plants, paint booths, hazardous waste-handling facilities, pipeline valves, and maintenance equipment.
