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.
