Stainless steel cable pull switches for harsh environments
Allen-Bradley Guardmaster have launched a stainless steel version of their Lifeline 4 cable-pull switch for use in applications where corrosion resistance is an essential requirement. The 316-bodied Lifeline 4 is suitable for both internal and external use, providing a constant emergency stop facility along exposed conveyors and around awkward machinery.
Offering the benefits of IP66 protection for hose downs, and IP67 for full immersion, the stainless steel Lifeline 4 is designed to address the problems of continuous operation in demanding environments. The markings on the lid and on the side of the product are laser etched to ensure they cannot flake off, while the pads on the base of the unit have been built up, to allow washdown water to flow behind the switch more easily.
Complementing these external design features is a positive-mode operating mechanism that delivers positive and immediate operation in response to a definite deflection, while at the same time protecting against the effects of nuisance tripping and thermal expansion.
In addition to its integrated cable status indicator and four sets of contacts, the stainless steel Lifeline 4 also includes a switch lockout and lid-mounted, mushroom-headed emergency stop button, which conforms to EN418 and provides an E-stop facility at the extreme ends of the cable span.
In common with all versions of the Lifeline range, the stainless steel Lifeline 4 is easy to set-up and maintain. When correctly installed, a pair of stainless steel Lifeline 4 switches will serve a safety grab wire up to 75m in length, helping to reduce the number of emergency stops required on extensive plant layouts.
Suitable for OEM use, the stainless steel Lifeline 4 system meets the requirements of EN418 ‘Safety of Machinery – Emergency Stop Equipment’ and also conforms to ISOTR 12100, ISO13850, EN60947-5-5 and IEC60947-5-1. The product is CE marked and offers the additional benefit of cULus and TUV approvals.
