Rockwell Automation has introduced a patented, solid-state cable-pull switch to help enhance industrial safety without sacrificing productivity. The Allen-Bradley Guardmaster Lifeline 5 cable-pull switch from Rockwell Automation is a solid-state, cable-pull E-stop with patented, microprocessor-based technology.
Traditional cable-pull switches can be prone to nuisance trips and unreliable operation due to temperature-based changes in cable tension. The solid-state operation of the Lifeline 5 cable-pull switch offers an electronic, rope-monitoring system to compensate for thermal expansion and cable sag.
The Lifeline 5 switch provides access to the E-stop function, stopping a machine hazard with a pull of the attached cable. The patented, microprocessor-based solution helps to simplify setup and allows for more efficient maintenance and troubleshooting. The LED indicators assist in cable tensioning for setup while providing switch status and diagnostics during operation.
Available in die-cast aluminum or stainless-steel housings with IP66 and IP67 environmental ratings, respectively, the Lifeline 5 switch helps to optimize productivity by combining with diagnostics that can help prevent unplanned downtime. The die-cast aluminum model also offers an optional, integrated E-stop button for additional application flexibility.
