Introduction

The MICRO SWITCH™ EX Series switches feature the smallest UL-listed enclosure available for hazardous locations. The EX Series switch housing 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 amperes while providing ample wiring space for easy installation. Single and dual conduit openings are available. The dual conduit opening allows wireway connections for multiple switches. The EX Series can be mounted from all four sides of the switch. With over 80 years of switch manufacturing experience covering most environmental types, Honeywell delivers proven technology with superior quality and service worldwide. The EX Series is certified by multiple agencies, including CE, IEC Ex, UL, CSA, and the ATEX Directive. A variety of actuator options make the EX Series ideal for indoor explosion-proof applications. It is the smallest UL-listed, power-load-rated switch available for hazardous locations.

Features

• Commonly used in space-constrained applications, MICRO SWITCH™ EX Series switches feature ample wiring space to reduce installation time. Four-sided mounting with optional mounting brackets simplifies installation in most applications. The EX Series offers dual conduit openings on select models, allowing wire threading for connecting multiple switches in a single circuit.
• Wide product and variant selection with multiple actuator styles, including pin plunger and rotary configurations. Switch capacity ranges from 1A for low-energy loads to 20A for most industrial electrical loads.
• Flexible design with field-adjustable rotary actuators for quick setup and application adaptation. Roller lever actuators feature 360° rotational adjustment. 1EX and 2EX certified models include dual conduit openings for "feed-through" wiring, or allow users to separate wiring of a double-pole switch so each pole exits from one side.

Applications

• Industrial Paint Booths: Position detection in automated paint booths used by indoor industrial painting companies; door position detection in automotive paint booths to ensure doors are closed before painting.
• Oil and Chemical Plants: Valve position detection in potentially explosive indoor environments at refineries and chemical plants.
• Processing Facilities: Indoor position sensing in grain handling and processing facilities, pulp and paper mills, lumber mills, and other types of facilities where airborne dust and fine particles may pose explosion risks.
