Conveyor Belt Monitoring Systems

Our KBT-Europe product line’s safety pull cord switches, belt misalignment switches, limit switches, and belt damage detectors are particularly rigid and guarantee a long service life in harsh industrial environments and in mining.

Pull Cord Switches | Pull Cord Emergency Switches

Pull cord emergency switches (aka safety pull cord switches) connect to a rope that runs along the accessible sides of the conveyor. A person in danger can switch off the conveyor with a short, strong pull on the rope. The safety pull cord switch locks in the triggered position and must be manually unlocked when the hazardous situation is over.
