Patented, Solid-State Cable-Pull Switch Enhances Industrial Safety
12 May 2017
Industrial automation customers can now improve safety without sacrificing productivity with the most advanced cable-pull switch on the market. The Allen-Bradley Guardmaster Lifeline 5 cable-pull switch from Rockwell Automation is the first solid-state, cable-pull E-stop in the industry with patented, microprocessor-based technology.
Traditional cable-pull switches are 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.
“Because the Lifeline 5 cable-pull switch is a solid-state switch, there is no mechanical wear that is often associated with traditional switches,” said Steve Tambeau, product manager, Rockwell Automation. “That means increased uptime and more reliable safety function over a longer duty cycle.”
The Lifeline 5 switch provides constant access to the E-stop function, stopping a machine hazard with a simple pull of the attached cable. The patented, microprocessor-based solution simplifies setup and allows for more efficient maintenance and troubleshooting. The easy-to-see LED indicators assist in cable tensioning for quick, precise setup while providing switch status and diagnostics during operation.
Available in die-cast aluminum or rugged, stainless-steel housings with IP66 and IP67 environmental ratings, respectively, the Lifeline 5 switch helps optimize productivity by combining maximum reliability with diagnostics that can help prevent unplanned downtime. The die-cast aluminum model also offers an optional, integrated E-stop button for even greater application flexibility.
