Honeywell hazarous area 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 — fumes that otherwise could cause an explosion outside the switch.
Best used for presence or absence detection where physical contact is permissible, Honeywell S&C hazardous location switches can be found in the most ingenious solutions and the most rugged machinery — in the most volatile environments. Designed for reliability, O-ring seals make the switch weatherproof, watertight and dust-tight, but are located outside flame paths so explosion-proof requirements are preserved.
