New Stainless Steel Lifeline 4 Cable Pull Switch Protects Your
Personnel and Equipment, Even in the Harshest Environments

A Proven Safety Switch, Made
Even Tougher
The standard Lifeline 4 product has a proven
track record for providing your personnel
constant access to an emergency stop around
awkwardly-shaped machinery and alongside
conveyors. However, there are some
applications where the standard Lifeline 4 is not
suitable. In response, Rockwell Automation has
introduced the Stainless Steel Lifeline 4.
The only investment cast stainless steel cable
pull switch on the market, the new Stainless
Steel Lifeline 4, with its IP66/IP67 enclosure
rating, is an ideal solution for use on long
conveyor systems in harsh environments, e.g.
outdoor applications or washdown areas. In
addition, the 316 stainless steel construction
provides enhanced corrosion resistance.
Offering the same functionality as the standard
Lifeline 4 product, the Stainless Steel Lifeline 4
is available with 2 N.C. safety contacts and 2
N.O. auxiliary contacts in M20, ½ in NPT or
quick disconnect versions. However, the
Stainless Steel Lifeline 4 differs from the
standard product in the following ways:
! Investment cast 316 unpainted stainless steel
housing as opposed to a painted die-cast zinc
alloy.
! External mounting holes, which are a function
of the casting process.
! The seal between the lid and the body
protrudes slightly so that it is not a food trap.
! Product markings (e.g. part numbers) are
permanently laser-etched on the lid and side of
the switch.

A number of accessories suitable for harsh conditions are also being offered to
complete the solution, including installation kits, corner pulleys and replacement
lids. For general ordering information, refer to the reverse side of this Product
Profile; more detailed information is available on the product catalog pages.
