4B Pullswitch - Conveyor Safety Stop Switch - 1

Product Information 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.
