The Guardian Line GLM from IDEM are safety rope pull switches with a compact yet robust yellow diecast housing that protect short conveyor lengths of upto 50m and offer a choice of fittings depending on the application. They are designed to be mounted on machines and sections of conveyors which cannot be protected by guards and unlike emergency stop pushbuttons can be activated from any point along the length of rope pull to provide robust emergency stop protection.
In combination with a dual channel safety monitoring relay these safety rope switches can be used as emergency stop devices and monitored for up to Category 4 to EN 954-1 or PLe ISO 13849-1. The Guardian Line conforms to ISO 13850 and IEC 60947-5-5 and has a positive mechanical linkage between the switch contacts and the wire rope, as well as wire breakage monitoring. Once the rope is pulled, anywhere along its length, the safety contacts are positively opened and the auxiliary contacts are closed. The switches are mechanically latched and can only be returned to the operational condition by pressing the blue reset button, as required by ISO 13950.
