The higher of the two values is to be applied.
An optical sensor arrangement with separate emitter and receiver, which reacts to
an interruption of the light beam directed between the emitter and the receiver.
Optical aid, whereby retro-reflection is created by means of multiple reflection on its
pyramid shaped inner surfaces.
Ultraviolet light in the wavelength range of 380 – 10 nm.

Approaching of calibrating plate centrally to the reference axis.
Standard specified range of light barriers. This range is established in a dry and
clean environment and includes a reserve range to cover sundry tolerances. In the
case of retro-reflective sensors this range refers to the reflector specified for the
