2TLA050204R0332 ABB LineStrong3D Pull Wire E-Stop 250 m

Why Choose the ABB 2TLA050204R0332 LineStrong3D Pull Wire E-Stop?

The ABB 2TLA050204R0332 is a robust LineStrong3D pull wire emergency stop safety switch designed to provide emergency-stop protection over long conveyor lines, machinery and other extended industrial installations. As part of the ABB LineStrong series, this model allows personnel to initiate an emergency stop from anywhere along an installed pull-wire system rather than requiring access to a single fixed emergency-stop station.

The LineStrong3D is a double-sided pull-wire switch with wire entries from both sides, making it particularly suitable for long machinery and conveyor applications. This configuration supports an emergency-stop wire span of up to 250 m and incorporates 4NC + 4NO contacts for integration with industrial safety and control circuits.

Built around a durable yellow die-cast housing, the 2TLA050204R0332 provides an IP67 enclosure rating for demanding industrial environments. An integrated emergency-stop button and LED status indication provide additional local control and visual status information, while M20 conduit entries simplify connection to machine wiring.

Key Advantages

• Heavy-duty pull wire emergency-stop switch for industrial machinery and conveyors.
• Supports pull-wire installations extending up to 250 m.
• Double-sided LineStrong3D design accepts pull wire from both sides of the switch.

Long-Range Emergency-Stop Protection

Pull-wire emergency-stop switches provide a practical method of protecting machinery where operators may need to initiate an emergency stop from multiple positions along a long installation. A correctly installed pull wire runs alongside the hazardous area, allowing an operator to actuate the safety switch by pulling the wire rather than travelling to a fixed emergency-stop control.

The ABB LineStrong3D is particularly suited to extended applications because its double-sided operating arrangement allows pull wire to be connected on both sides of the switch. Combined with its long 250 m wire capability, multiple safety contacts, local E-stop button and LED indication, this makes it a versatile safety component for conveyor and material-handling systems.

Typical Applications

• Long industrial conveyor systems.
• Material handling and transfer lines.
• Automated production machinery.
• Packaging and processing lines.
• Warehouse conveyor installations.
• Bulk material handling equipment.
• Industrial machinery requiring accessible emergency-stop protection over extended distances.
