Rotation angle (approximate value)
Max 270° (-90° and +180° being 0° the condition where the two interconnected surfaces are on the same plane).
The hinge can reach -90 ° but this condition must not be used for CFMR-NO execution.
Do not exceed the rotation limit angle so as not to prejudice the correct operation of the return spring.
To choose the convenient type and the right number of hinges for your application, see the Guidelines
Features and performances
CFMR hinge is used for the automatic re-closing or re-opening of the door by the return spring.
The torque varies progressively with the opening/closing angle of the hinge.
In special stress resistance tests, the return spring has exceeded 100,000 cycles while keeping the torque values unchanged.
