Hazardous Area Limit Switches

BX Series

EAC. UL. CSA. ATEX (CE). IEC Ex. INMETRO. KOSHA. NEPSI. IP67, NEMA 1, 3, 4, 6, 13. Div 1 & 2: Class I: B, C, D. Div 1 & 2: Class II: E, F, G

The MICRO SWITCH BX/BX2 Series are designed for applications in hazardous or explosive environments requiring a rugged, durable switch virtually anywhere in the world. To comply with explosion-proof switching requirements, the flame path within the switch housing is designed to contain and cool escaping hot gases and fumes that could cause an explosion outside of the switch.

Regardless of where the equipment or machinery is designed, built, or installed, BX and BX2 Series products carry global agency coverage. Honeywell offers two versions of the BX series switch: the standard BX Series features an aluminum housing, while the BX2 Series features a 316L stainless steel housing.

The stainless steel housing adds additional resistance against corrosion in applications exposed to aggressive, caustic agents, as well as those often present in chemical processing plants, off-shore/near-shore sites, and other hazardous areas. Both products are weather sealed for outdoor use and designed for explosive gas/dust environments. All operating heads of the BX/BX2 Series are field adjustable at 90° increments.
