Heavy-Duty Safety Rope Pull Switches

Featured Product from OMEGA Engineering, Inc.


GLS and GLS-SS Series safety rope switches 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, GLS and GLS-SS Series 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.

  • Mount on Machines and Conveyors Which Cannot be Protected by Guards
  • Protect Conveyors Up to: 250 m (820') Using Two Switches or 200 m (656') Using a Single Switch
  • Mushroom Type Emergency Stop Button
  • Reset Button-Push to Reset Following Switch Activation by Rope Pull
  • Wire-Breakage Monitoring
    GLHD Series safety rope switches 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, GLHD Series 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, GLHD Series safety rope systems can be used as emergency stop devices monitored for up to PLe to ISO13849-1. All GLHD Series safety rope emergency stop switches conform to ISO13850 and EN60947-5-5. They have a positive mechanical linkage between the switch contacts and the wire rope. The switches have wire-breakage monitoring. On pulling the rope the safety contacts are positively opened and the auxiliary contacts are closed. The switches are mechanically latched and can then only be returned to the operational condition by pressing the blue reset button as required by ISO13850.
    GLHD Series are heavy-duty safety rope pull switches designed to protect long conveyor lengths up to 250 m (820'). The die-cast housings are robust to survive indoor or outdoor use including washdown NEMA 6 (IP67) rating. Lengths over 2 Km can be achieved with less than 20 switches. An easily visible bi-color LED is available to show switch status from a distance. GLHD Series switches have 4NC 2NO contacts to ensure flexibility with all modern control applications. Shorter rope spans up to 200 m (656') can be achieved by using just one switch therefore making a cost effective solution and reducing electrical wiring runs.
