Product Description

DESCRIPTION

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 theswitch's four sides.

 

FEATURES

• Compact and rugged housing

• Ample wiring space that eases installation time

• Four-sided mounting with optional mounting bracket

• Dual conduit openings on select models

• 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

• Manufactured for harsh and explosive environments

• International approvals for use aroundthe world

 

VALUE TO CUSTOMERS
