Allen-Bradley Guardmaster Lifeline 5 cable-pull e-stop switch

The Allen-Bradley Guardmaster Lifeline 5 cable-pull switch from Rockwell Automation is a solid-state, cable-pull e-stop with 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.

The switch provides constant access to the e-stop function, stopping a machine hazard with a simple pull of the attached cable. The microprocessor-based solution simplifies set-up and allows for more efficient maintenance and troubleshooting. The easy-to-see LED indicators assist in cable tensioning for quick, precise set-up while providing switch status and diagnostics during operation.

The unit is available in diecast aluminium or rugged stainless steel housings with IP66 and IP67 environmental ratings, respectively. The diecast aluminium model also offers an optional, integrated e-stop button for greater application flexibility.
