Elesa CFSW Safety Hinges Elesa CFSW Safety Hinges have a built in safety multiple switch. The hinges have a positive opening in compliance with IEC EN 60947-5-1 annex K. The separation of the electrical contacts is the direct result of an actuator action on which an action force is applied with non-elastic elements, that is to say not dependent on, for example, spring-like elements. The contact elements guarantee a self-cleaning action of the silver-alloy pastes. The technopolymer housing of the CFSW hinge guarantees the double insulation of the internal circuits, therefore there is no need of grounding connection. Furthermore, the housing protects the electric contacts from shocks, atmospheric agents and accidental penetration of tools. Features and Benefits IP67 protection Easy to assemble Typical Applications Hinge with built-in multiple switch (ELESA patent) is a safety device because in case of accidental opening of doors, machine protections, or safety doors on machines and production equipment, it automatically breaks off the power supply hence protecting the operators.
