2TLA050200R0030 ABB LineStrong1 Pull Wire Emergency Stop 50 m

Why Choose the ABB LineStrong1 Pull Wire Emergency Stop?

The ABB LineStrong1, order code 2TLA050200R0030, is an industrial pull wire emergency stop safety switch designed to provide emergency-stop access over extended sections of machinery. Instead of requiring an operator to reach a single push-button station, the LineStrong1 allows the emergency-stop function to be initiated by pulling the installed grab wire.

This LineStrong1 configuration provides 2 NC + 2 NO contacts in a robust yellow die-cast housing with three M20 conduit entries. The system supports a pull-wire span of up to 50 m, making it particularly suitable for conveyors, production lines and other elongated machinery where emergency-stop access is required along the operating area.

The LineStrong1 incorporates monitoring of the pull-wire arrangement so that the safety contacts respond when the wire is pulled or when wire tension is lost. With IP67 enclosure protection and safety capability up to PL e / Category 4 and SIL 3 depending on the overall system architecture, it provides a robust solution for demanding industrial machine safety applications.

Key Advantages

• Provides accessible pull-wire emergency stopping over spans up to 50 m.
• 2 NC + 2 NO contacts provide versatile integration with machine safety and indication circuits.
• Robust yellow die-cast housing for industrial machinery applications.
• IP67 protection supports installation in dusty and wet industrial environments.
• Monitors the pull wire for both pull activation and loss of tension.
• Can support safety functions up to PL e / Category 4 and SIL 3 when incorporated into an appropriately designed safety system.

Emergency Stop Protection Along Extended Machinery

Pull-wire emergency stop switches provide a practical means of protecting machinery where operators may need to initiate an emergency stop from multiple positions along an extended working area. A tensioned safety wire is routed alongside the hazardous machinery so that an operator can activate the emergency-stop function by pulling the wire from an accessible position.

The ABB LineStrong1 is designed so that the safety contacts respond to operation of the pull wire and to abnormal loss of wire tension, such as a broken or released wire. This monitored arrangement makes the LineStrong1 particularly suitable for conveyors and other long machinery where a single conventional emergency-stop push button would not provide convenient access throughout the operating area.

Typical Applications

• Conveyor systems and material handling equipment.
• Production and assembly lines.
• Packaging and processing machinery.
• Warehousing and distribution equipment.
• Automated manufacturing systems.
• Long machinery requiring accessible emergency stopping along its operating length.
• Industrial machine safety systems requiring monitored pull-wire emergency stops.
