440E Cable Switch with E-Stop, Straight, 2m, NO/NC
Product Details

Lifeline 4, Hazardous Area

Designed to meet the latest standard for emergency stop equipment, EN418 and is suitable for Zone 1 & 2 environments
Can be installed along or around awkward machinery such as conveyors and provides a constant access emergency stop facility
Status indicator makes the system easy to set-up and maintain for spans up to 75 metres
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
A mushroom head emergency stop button is included on the unit to provide total E-stop access even at the extreme ends of the span and is sealed to IP66
Rugged construction using die cast alloy and stainless steel to withstand harsh conditions
2 of the 3 cable access points are sealed to meet Ex. spec
Cable access is therefore restricted to one point of ingress, underside entry
Approval Certificate available on request


Our rope switch kits contain all fittings necessary for installation. Available in 5, 10, 20, 30, 50 and 75 metre lengths.
