IDEM Guardian Line GLS-SS Stainless Steel Safety Rope Pull Switches The Guardian Line GLS-SS from IDEM are safety rope pull switches with a stainless steel 316 housing able to withstand the tough environments found in the Food and Pharmaceutical industries. The fixing holes are under the cover of the switch to prevent food trap areas and can withstand chemical and detergent washdown due to all stainless steel parts and robust IP69K sealing by using integral bellows and gaskets. 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. Switch mechanism will latch the instant the safety contacts open, ISO13850 standard Upto 80m (260 feet) can be covered using only a single switch and safety spring Upto 100m (328 feet) can be covered using two switches Positive break contacts to IEC60947-5-1 Stainless steel 316 housing IP69 protection Rugged integral sealing bellows mean they can be high pressure hosed All internal screws are stainless steel Easy to wire with 3 x M20 conduit entries 4 pole 2NO / 2 NC Note 826-4108 has an LED, 826-4117 has an E-stop, 82...
