Honeywell Series EX Limit Switch, Roller Lever Actuator, Aluminium Housing - EXD-AR-3


This limit switch provides mechanical position sensing for industrial control and safety applications. It operates with a roller lever actuator and snap-action contacts to detect movement or travel end points within automated and machinery systems. The device is intended for side mounting and connects via a cable terminal, offering a Compact solution for electrical interlocking and positional feedback in harsh environments.

Features and Benefits:


• 2NO2NC contact arrangement gives flexible circuit configurations
• Snap-action contacts deliver Rapid state changes for accurate detection
• Aluminium housing offers robust protection in industrial settings
• Operating range -40 to 71°C supports varied temperature environments
• Roller lever actuator enables reliable physical engagement with moving parts
• Cable Terminal simplifies fixed wiring installations on site

Applications


• Suitable for conveyor end-of-travel detection in manufacturing lines
• Ideal for limit sensing on packaging and material-handling machinery
• Used with industrial actuators for position feedback in assembly cells
• Can be used for safety interlocks on guards and access panels
• Suitable for testing rigs requiring repeatable mechanical switching

What mounting orientation is required for correct installation?


It is designed for side mounting to align the roller lever with lateral motion paths and ensure proper mechanical engagement.

Which approvals indicate its suitability for regulated installations?


It holds RoHS, CSA and UL recognitions, indicating adherence to specific material and safety standards relevant to industrial equipment.

How does the contact type affect switching performance?


The snap-action mechanism ensures quick transition between states, minimising arcing duration and improving repeatability in Rapid cycling scenarios.

What enclosure material benefits corrosion resistance and mechanical strength?


The body is machined from aluminium, which balances mechanical durability and resistance to many industrial atmospheres.

What cable connection style does it use for wiring?


Electrical connection is provided via a cable Terminal designed for permanent field wiring.
