Patented, Solid-State Cable-Pull Switch Enhances Industrial Safety

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 Christo Buys, Business Manager for Control Systems, Rockwell Automation sub-Saharan Africa. “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 aluminium or rugged, stainless-steel housings with IP66 and IP67 environmental ratings, respectively, the Lifeline 5 switch helps optimise productivity by combining maximum reliability with diagnostics that can help prevent unplanned downtime. The die-cast aluminium model also offers an optional, integrated E-stop button for even greater application flexibility.
