Safety Edges
Safety EdgeSafety Edges are used to protect against injury from shearing or crushing hazards associated with scissor lifts, roller shutter doors, machine guards, lifting tables, theatre stages etc. Once activated they will immediately switch off the power source. The Haake range of Safety Edges use force break contact technology enabling them to be connected via standard safety relays rather than special control units.
Safe Edges conform to the requirements of a Category 3 system as defined in BS EN 945-1 safety of machinery - safety related parts of control systems 1997.
The photograph shows a Safety Edge on a lift table. Should the Safety Edge be pressed the power to the table is immediately isolated, stopping the dangerous movement.
