Emergency Stop Devices
Cable (Rope) Pull Switches
Lifeline 4
Description
The Lifeline 4 cable/push button operated system can be installed
along or around awkward machinery such as conveyors and provide
a constant emergency stop access.
The Lifeline 4 is the only device of its kind to incorporate the
following features in one unit making it the most versatile cable
switch on the market.
1. The positive mode mechanism ensures 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.
2. A mushroom head emergency stop button is included on the unit
to provide E-Stop access even at the extreme ends of the span.
3. The cable status indicator makes the system easy to set up and
maintain for spans up to 125 meters.
4. Four sets of contacts are provided: 2 N.C. + 2 N.O., 3 N.C. +
1 N.O., or 4 N.C. contacts.
5. Sealed to IP 66 with rugged construction using die cast alloy and
stainless steel to withstand harsh conditions.
