The Safety Pull Switch is mounted on or alongside the conveyor stringer, with one end of the pull wire fastened to a fixed post and the other end fixed on to the actuator arm. The pull wire is supported by standoff eyebolts every 3m.
The distance between the switch and fixed post should not exceed 24m. The spacing between two switches should be no more than 48m.
When the actuator arm displaces (rotates) to the alarm position by force acting on the pull-wire, the microswitch is activated and interlocked until reset manually. The standard switch is protected to IP65, suitable for both indoor and outdoor installation.
Where the optional nickel plated housing is specified, it can be used in acid, alkaline or salty environments. The nickel plated surface is well suited for highly corrosive application.
