The 2366.1 is a square Surface Symbol Illumination System for surface and background illumination for diverse applications due to its low height. Despite its low height, this module offers excellent surface radiation homogeneity. The insertion rate does not depend on the module itself, as only the SMD TOP LEDs are initially inserted for the soldering process, so that also a large number of components can quickly be positioned on-line. This takes place with extremely high co-planarity, as large or complex illumination system is initially configured on subsequent insertion of the surface module. The insertion itself is easy and reliable via fixing pins in a tried and tested design. Furthermore it is possible to design illuminated, capacitive touch panels.
