Abstract
A device for preventing shearing or pinching of a foreign object is suitable for use in SMIF (Standard Mechanical Interface) systems. A barrier which is constructed as a solid body is fastened at and displaceable relative to one of two parts which can move past one another. The barrier is fastened to this part at a distance above electric contact elements in three-point formation, which distance is greater than the maximum braking distance required for stopping movement. The barrier is substantially adapted in shape and position at its shearing line to the part moving past it, wherein contact is broken in at least one contact element and accordingly in an otherwise closed circuit when the barrier is displaced relative to the part. Such devices serve to prevent injuries and damage in the operation of systems in which two parts move past one another at a slight distance.
