Allen-Bradley Guardmaster Lifeline 5 cable-pull switch
June 7, 2017
The Allen-Bradley Guardmaster Lifeline 5 cable-pull switch features microprocessor-based technology and an electronic, rope-monitoring system to compensate for thermal expansion and cable sag. Available in die-cast aluminum or stainless steel housings with IP66 and IP67 environmental ratings respectively, the switch offers constant access to the E-stop function, stopping a machine hazard with a pull of the attached cable. The LED indicators provide switch status and diagnostics during operation.
