MICRO SWITCH Hazardous Area Switches 002306 BX BX2 Series Issue 9 Datasheet FEATURES Approvals: UL, CSA, ATEX (CE), IEC Ex, INMETRO (Brazil), NEPSI Ex (China), and KOSHA/KTL (select listings - Korea) Sealed to IP67, NEMA 1, 3, 4, 6, 13 Industry-leading breadth of products Two rugged designs are available: aluminum or corrosion- resistant stainless steel head and body A diaphragm seal between head and body provides an extra measure of protection Optional fluorocarbon seals are available for harsh chemical or higher temperature environments Secure head-to-body retention with the head in any one of four positions 90 apart Self-lifting pressure plate terminals saves wiring time. Wide variety of non-sparking actuators, switch options, and DESCRIPTION head styles for design flexibility The MICRO SWITCH BX/BX2 Series are designed for Rotary actuated heads are field adjustable for CW actuation, applications in hazardous or explosive environments requiring CCW actuation, or both to reduce inventory a rugged, durable switch virtually anywhere in the world. To Choice of silver or gold-plated contacts comply with explosion-proof switching requirements, the flame path within the switch housing is designed to contain APPLICATIONS and cool escaping hot gases and fumes that could cause Grain elevators an explosion outside of the switch. Regardless of where the Control valves and actuators equipment or machinery is designed, built, or installed, BX and Off-shore and on-shore drilling BX2 Series products carry global agency coverage. Pipelines Petrochemical and chemical plants Honeywell offers two versions of the BX series switch: the Water treatment plants standard BX Series features an aluminum housing, while Paint booths the BX2 series features a 316L stainless steel housing. The Conveyors (above-ground) stainless steel housing adds additional resistance against Pulp and paper corrosion in applications exposed to aggressive, caustic Hazardous waste handling agents, as well as those often present in chemical processing plants, off-shore/near-shore sites, and other hazardous VALUE TO CUSTOMERS areas. Both products are weather sealed for outdoor use and Around-the-world use in hazardous areas with international designed for explosive gas/dust environments. All operating approvals: UL, CSA, ATEX (CE), IEC Ex, INMETRO, KOSHA/ heads of the BX/BX2 Series are field adjustable at 90 KTL, and NEPSI Ex (China) increments. Industry-leading breadth of product offering that includes: DIFFERENTIATION BX (aluminum housing) and BX2 (stainless steel housing) Top-of-the-line environmental sealing combined with limit switches for hazardous locations Honeywell expertise for hazardous location package design 303 stainless steel operating shaft on sintered bronze provides the right product for the right application bearing for enhanced mechanical life and operational Exclusive teller tab on levers ensures proper torque. When reliability the tab cannot be moved, the lever is tight enough to prevent slippage PORTFOLIO Honeywell offers a wide range of limit switches in different size packages and hazardous environments. These limit switches include the BX/BX2 Series, CX Series, EX Series, LSX Series, GXS Series, and 14CE100 Series. To view the entire product portfolio, click here.
