The Guardian line stainless steel IP69k safety rope pull switches and grab wire pull cords are designed to be mounted on machines and sections of conveyors which cannot be protected by guards.
In contrast to traditional mushroom head type emergency stop buttons, Grab Wire Safety Rope Switches can initiate the emergency command from any point along the installed rope length and provide robust Emergency Stop Rope Pull protection for exposed conveyors or machines.
In combination with a dual channel safety monitoring relay, IDEM’s range of safety rope pull switches and grab wire pull cords can be used as emergency stop devices, monitored for up to PLe in acc. with ISO13849-1.
All IDEM safety rope pull switches conform to ISO 13850 and IEC 60947-5-5 and have a positive mechanical linkage between the switch contacts and the wire rope. The rope pull switches have wire breakage monitoring.
On pulling the rope, the safety contacts are positively opened and the auxiliary contacts are closed. The safety rope switches are mechanically latched and can then only be returned to the operational condition by pressing the blue reset button as required by ISO 13850.
An optional 2 colour LED indicator is available to enable switch status to be viewed from a distance.
