MICRO SWITCH™ EX Series Hazardous Location Limit Switches
MICRO SWITCH™ EX Series switches feature the smallest UL-listed housings available for use in hazardous locations. The EX Series switch cavity is designed to cool expanding gases below the ignition temperature of the surrounding explosive atmosphere.
The EX Series is capable of switching up to 20 amps while providing ample wiring space for ease of installation. Single and double conduit openings are available. Dual conduit openings may allow for through wiring of multiple switches. The EX Series can be mounted from any of the switch’s four sides.
– Honeywell has over 80 years of switch manufacturing experience covering most environment types.
– Proven technology plus superior quality and service are offered world-wide. The EX Series holds multiple agency approvals, including CE, IEC Ex, UL, CSA, and ATEX directives.
– Multiple actuator options make the EX Series a good choice for indoor explosion-proof applications
– Smallest UL-listed, power-load carrying switch available for use in hazardous locations
Often used in applications where space is at a premium, MICRO SWITCH™ EX Series switches feature ample wiring space that eases installation time. The four-sided mounting with optional mounting bracket simplifies installation in most applications. The EX Series offers dual conduit openings on select models that allow for through wiring making it easier to wire multiple switches in a single circuit.
Broad range of actuator styles available in pin plunger and rotary configurations. Switching capacity from 1 A for low energy loads, up to 20 A for most industrial electrical loads.
Rotary actuators are field adjustable for quick set up and application adaptability. Roller lever actuators are adjustable through 360° of rotation. 1EX and 2EX listings have dual conduit openings enabling “wire through” or allowing the user to split the wiring of a double pole switch with one pole exiting each side.
Potential Applications
Position detecting in automated paint booths used by indoor industrial painting companies. Automotive paint booth door position detection assures the door is closed before paint can be applied.
Position sensing indoors at grain handling and processing plants, pulp and paper processing, lumber and other types of facilities where dust and other fine particles in the atmosphere may create the potential for explosions.
Valve position in indoor potentially explosive environments in petroleum refineries and chemical plants
