Large areas of danger often have to be secured where the use of protective doors and emergency stop buttons is not possible. Barrier ropes in conjunction with rope pull switches are an effective alternative.
Examples are extensive production islands or conveyor belts. The rope is attached to the rope pull switches at both ends. In the event of danger, the system can be locked and switched off immediately and safely at any point on the tensioned rope by pulling it. Even if the rope breaks, the switches ensure that the machine comes to a standstill immediately.
This state remains locked until the reset button is actuated when the rope is correctly tensioned again.
There are different variants for different rope lengths. An additional emergency stop button can be installed on both sides of the switch.
