Leading Manufacturer of Safety Interlock Switches and Machine Guard Safety Switch Devices for Automation and Process Safety

Guardian Line Standard Duty Rope Safety Switch with Auto-Reset (GLS-AR)

The GLS-AR standard duty safety rope pull switch has been designed to protect medium to long conveyor lengths, where protection is required up to 100m (using 2 switches) or up to 80m (using 1 switch). The manual reset mechanism has been removed, meaning the GLS-AR will automatically reset upon release of the rope.
