MICRO SWITCH Hazardous Area Switches 002306 BX BX2 Series Issue 8 Datasheet FEATURES Approvals: UL, CSA, ATEX (CE), IEC Ex, INMETRO (Brazil), NEPSI Ex (China), KOSHA (select listings - Korea), and EAC (formerly GOST-R, Russia) 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. DESCRIPTION Wide variety of non-sparking actuators, switch options, and The MICRO SWITCH BX/BX2 Series are designed for head styles for design flexibility applications in hazardous or explosive environments requiring Rotary actuated heads are field adjustable for CW actuation, a rugged, durable switch virtually anywhere in the world. To CCW actuation, or both to reduce inventory comply with explosion-proof switching requirements, the Choice of silver or gold-plated contacts flame path within the switch housing is designed to contain and cool escaping hot gases and fumes that could cause APPLICATIONS an explosion outside of the switch. Regardless of where the Grain elevators equipment or machinery is designed, built, or installed, BX and Control valves and actuators BX2 Series products carry global agency coverage. Off-shore and on-shore drilling Pipelines Honeywell offers two versions of the BX series switch: the Petrochemical and chemical plants standard BX Series features an aluminum housing, while Water treatment plants the BX2 series features a 316L stainless steel housing. The Paint booths stainless steel housing adds additional resistance against Conveyors (above-ground) corrosion in applications exposed to aggressive, caustic Pulp and paper agents, as well as those often present in chemical processing Hazardous waste handling plants, off-shore/near-shore sites, and other hazardous areas. Both products are weather sealed for outdoor use and VALUE TO CUSTOMERS designed for explosive gas/dust environments. All operating Around-the-world use in hazardous areas with international heads of the BX/BX2 Series are field adjustable at 90 approvals: UL, CSA, ATEX (CE), IEC Ex, INMETRO, KOSHA, increments. NEPSI Ex (China), and EAC (formerly GOST-R, Russia) DIFFERENTIATION Industry-leading breadth of product offering that includes: Top-of-the-line environmental sealing combined with BX (aluminum housing) and BX2 (stainless steel housing) Honeywell expertise for hazardous location package design limit switches for hazardous locations provides the right product for the right application 303 stainless steel operating shaft on sintered bronze Exclusive teller tab on levers ensures proper torque. When bearing for enhanced mechanical life and operational the tab cannot be moved, the lever is tight enough to prevent reliability 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.
