2TLA050208R0332 ABB LineStrong3R Pull-Wire Emergency Stop Switch 125 m

Why Choose the ABB LineStrong3R Pull-Wire Emergency Stop Switch?

The ABB LineStrong3R is a heavy-duty pull-wire emergency stop safety switch designed to provide accessible emergency stopping along conveyors, production lines and other extended industrial machinery. Supplied under ABB order code 2TLA050208R0332, this LineStrong3 variant is configured for a right-hand pull-wire installation and supports wire spans of up to 125 m.

The LineStrong3R incorporates 4 normally closed and 2 normally open contacts, providing multiple contacts for safety circuits and auxiliary signalling. Its pull-wire mechanism allows personnel to initiate an emergency stop from accessible positions along the protected wire, while monitoring of the tensioned wire also enables the switch to respond if the wire becomes slack or breaks.

Designed for demanding industrial environments, the LineStrong3R features a robust yellow die-cast aluminium alloy housing with IP67 protection. An integral emergency-stop pushbutton provides local operation directly at the switch, while 24 V DC LED status indication gives clear visual feedback at the installation point.

Key Advantages

• Provides accessible pull-wire emergency stopping across spans up to 125 m.
• Right-hand configuration for installation at the appropriate end of a pull-wire system.
• 4 NC + 2 NO contacts support safety monitoring and auxiliary signalling.
• Integral emergency-stop pushbutton provides direct local emergency operation.
• Built-in 24 V DC LED status indication improves visibility of switch status.
• Pull-wire mechanism monitors both deliberate wire operation and loss of correct wire tension.
• Rugged IP67 yellow die-cast housing is designed for industrial environments.
• Can support safety systems up to PL e / Category 4 and SIL 3 depending on the overall safety architecture.

Reliable Emergency-Stop Protection Along Extended Machinery

The ABB LineStrong3R provides a practical method of extending emergency-stop access along machinery where fixed pushbuttons alone would not provide convenient coverage. A tensioned safety wire is routed along the protected area, allowing personnel to actuate the emergency-stop switch by pulling the wire from an accessible position. The mechanism also monitors wire tension so that a broken or slack wire can operate the switch rather than leaving the safety system unknowingly compromised.

The right-hand configuration determines the direction of the pull-wire installation relative to the switch, making the LineStrong3R the counterpart to the left-hand LineStrong3L. Its combination of long-span coverage, multiple positively operated safety contacts, local emergency-stop button, LED indication and rugged IP67 enclosure makes it well suited to conveyor and production-line safety systems.

Typical Applications

• Long conveyor systems and conveyor galleries.
• Material handling and bulk handling equipment.
• Automated manufacturing and assembly lines.
• Packaging and processing machinery.
• Warehousing and distribution conveyor systems.
• Production lines requiring continuous emergency-stop access.
• Industrial machinery with extended operator working areas.
• Machine safety systems requiring right-hand pull-wire installation.
