Open Conveyor Pull Cord Safety Stop Switch
APPLICATION
The Pullswitch is a failsafe taut wire emergency pull
cord stop switch for open conveyors.
METHOD OF OPERATION
PVC coated steel pull wires and pigtails connect
between the switches to provide easy installation
and continuous emergency stop access along the
length of the entire conveyor. Pullswitches can be
installed at 50m intervals, reducing overall system
cost. Quick location of a tripped switch is provided
by a standard reflector or optional flag marker, and
the tripped signal can be wired back to an indicator
panel or PLC. The Pullswitch’s IP65 / NEMA 4, 4X,
9 rated enclosure is made from polycarbonate and
stainless steel, making the housing corrosion
resistant and weatherproof. A total of six positive
break contacts inside the Pullswitch offer unique
operation and control. Two independent cam
operated switches with snap action mechanical
operation are provided for conveyor shutdown, and
four additional micro-switches signal for a slack wire
alarm.
