Through-beam sensor 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. Triple reflector Optical aid, whereby retro-reflection is created by means of multiple reflection on its pyramid shaped inner surfaces. UV light Ultraviolet light in the wavelength range of 380 – 10 nm. Visible light Light ranging from red to violet (approx. 780 – 380 nm wavelength). © Festo Didactic GmbH & Co. KG • FP 1110 203 13. Technical terms relating to proximity sensors 13.2 Terms for dimensional characteristic values Axial approach Approaching of calibrating plate centrally to the reference axis. Nominal range 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 sensor. Nominal switching distance Standard specifi...
