Why Choose the ABB LineStrong3LZ 2TLA050206R0322 Pull-Wire Emergency Stop Switch?
The ABB LineStrong3LZ 2TLA050206R0322 is a heavy-duty left-hand pull-wire emergency stop safety switch designed to protect long conveyors, production lines and other extended machinery. As part of the ABB Sensors/Switches product group, it allows personnel to initiate an emergency stop from accessible points along a correctly installed safety rope rather than relying solely on individual emergency-stop stations.
This LineStrong3LZ variant combines a rugged 316 stainless steel housing with 4NC + 2NO contacts, an integral emergency-stop pushbutton and 24 V DC LED status indication. The switch is the left-hand version of the LineStrong3Z arrangement and uses M20 conduit entries for industrial field wiring.
The LineStrong3LZ is designed for demanding environments and provides IP67 and IP69K protection. ABB specifies the LineStrong3L/R family for rope spans of up to 100 m with a single switch, with longer protection arrangements possible using appropriately configured switches. Its stainless steel construction makes it particularly suitable for applications where resistance to washdown, chemicals and corrosion is important.
Key Advantages
- Heavy-duty pull-wire emergency stop protection for extended machinery and conveyors.
- Left-hand LineStrong3LZ configuration for end-of-line rope installations.
- 4NC + 2NO contacts provide multiple safety and auxiliary circuits.
- 316 stainless steel housing for demanding industrial environments.
- Integral emergency-stop pushbutton provides local emergency actuation at the switch.
- Integral 24 V DC LED status indication assists machine and switch-state monitoring.
- IP67 / IP69K protection supports demanding washdown applications.
- Can support safety architectures up to PL e / Category 4 and SIL 3 when correctly integrated.

Heavy-Duty Pull-Wire Emergency Stop Protection
A pull-wire emergency stop system provides accessible emergency actuation along an extended section of machinery. The safety rope is correctly tensioned between the appropriate mounting and tensioning components, allowing an operator to pull the rope from an accessible position along its length to operate the LineStrong3LZ and initiate the associated emergency-stop function.
ABB LineStrong switches also monitor the condition of the rope system. The normally closed safety circuits are closed only when the system is correctly tensioned and the switch has been reset. Pulling the rope or causing a sufficient loss of tension operates the mechanism and changes the contact state. The LineStrong3LZ must then be manually reset after the cause of the emergency operation has been investigated and the rope system restored to its correct condition.
Typical Applications
- Long conveyor emergency-stop systems.
- Food and beverage production lines.
- Pharmaceutical manufacturing equipment.
- Washdown production environments.
- Material handling and bulk handling conveyors.
- Automated manufacturing and assembly lines.
- Packaging and processing machinery.
- Warehouse and distribution conveyor systems.
- Extended machinery requiring emergency-stop access along its operating length.
- Industrial applications requiring 316 stainless steel pull-wire safety equipment.
