Allen Bradley Guardmaster Rope Pull Switch Cable

Lifeline 4 Stainless Steel Rope Pull Switch

The Lifeline 4 rope pull switch can be installed along or around awkward machinery such as conveyors and provide a constant emergency stop access. It is made from stainless steel 316 and is suitable for applications where there are hygiene requirements, external use and other situations where a level of corrosion resistance is required.
The positive mode mechanism of the Lifeline 4 helps ensure that the contacts are immediately latched open on actuation and can only be reset by the intentional action of turning the blue reset knob. The design also protects against nuisance tripping and the effects of thermal expansion. The rope pull switch has a mushroom head emergency stop button to provide E-Stop access even at the extreme ends of the span. The cable status indicator on the Lifeline 4 makes the system easy to set up and maintain for spans up to 75 meters.
