Optical Safety edges

Optical Safety edges made by Pepperl+Fuchs make it possible to efficiently secure crushing and shearing edges on powered machine parts such as covers, doors, or flaps. A safety system consists of an external safety control unit, a thru-beam sensor, and a rubber profile, which is guided into an aluminum profile rail.

The robust rubber profile has a light pipe in which a thru-beam sensor generates a light path. If the profile is deformed by external pressure, the cross section of the light pipe is reduced and the switching device then responds and causes a stop. As a complete system, protection devices can be implemented up to performance level e, Cat. 4 according to EN ISO 13849, and the highest safety standards can be met.
