Description
Product Name: 440E-L13133 Allen Braley Controller module
Product details:
The Allen-Bradley 440E-L13133 is part of the GuardMaster Lifeline 3 series of cable pull switches. It is activated by pulling a wire or rope that runs the length of the protected area.
-
Type: Cable Pull Safety Switch (or Rope Pull Switch).
-
Function: Provides an emergency stop (E-stop) signal when the cable is pulled, slackened, or broken, ensuring personnel safety.
-
Housing: Die-cast aluminum alloy, designed to withstand harsh industrial environments.
-
Reset: Features a blue reset button to re-engage the machine after activation.
-
Indicator: Includes a clear tension indicator/status display to ensure proper cable tensioning and switch status (tripped/ready).

Product Advantages (产品优势)
The 440E-L13133 switch offers several key advantages for machine safety:
-
Large Monitoring Area: It can monitor extensive machine lengths, reducing the number of individual E-stop buttons required.
-
Personnel Safety: Provides “reach-in-and-trip” protection, allowing operators to stop the machine from any point along the rope’s length in an emergency.
-
Robust Construction: The die-cast housing and IP66 rating make it highly durable and resistant to water, dust, and general industrial wear.
-
Positive Operation: The safety contacts are positively driven, meaning they are mechanically forced open upon activation, complying with the highest safety standards (e.g., up to PLe or Category 4).
-
Status Indication: The integrated tension indicator simplifies installation and maintenance by ensuring the cable is properly tensioned for reliable operation.
Precautions (注意事项)
To ensure the safety switch operates reliably and effectively, observe the following precautions:
-
Proper Tensioning: The cable must be tensioned correctly using the integrated indicator. Over-tensioning can lead to nuisance tripping or switch damage, while under-tensioning can prevent reliable operation.
-
Cable Support: Use appropriate intermediate supports and guides (eye bolts and tensioners) to prevent excessive cable sag, especially over longer spans.
-
Clearance: Ensure the emergency pull cable is accessible and unobstructed along its entire length.
-
Reset Procedure: Always investigate the cause of the emergency stop activation before pressing the blue reset button to re-energize the machine.
-
Safety Circuit: The N.C. safety contacts must be wired into a safety monitoring relay or safety PLC (e.g., an Allen-Bradley GuardMaster relay) to meet required safety performance levels.
Product Applications (产品应用)
The 440E-L13133 is widely used in industrial settings where extensive machine guarding is required:
-
Conveyor Systems: Used for continuous emergency stop protection along the entire length of material handling conveyors.
-
Packaging Machinery: Applied on long filling or wrapping lines.
-
Assembly Lines: Providing accessible E-stop functionality across large manufacturing cells.
-
Printing Presses: Used to quickly shut down long printing or paper-handling machines.
-
Process Machinery: In any application where a machine’s hazard zone is too large for conventional E-stop buttons to provide adequate coverage.
