2-1 General
The light curtain consists of one bar with light emitting optical elements and of one with
receiving optical elements. The photosensitive elements are scanned in sequence, thus
broken rays are detected.
F3ET2 features optical synchronisation and does not require synchronization wire between
transmitter and receiver. The sync-function is provided by the upper beam located on the
opposite side of the connector (see illustration below). During operation this beam must always
be kept free. Otherwise it will result in a longer response frequency of the light curtain.
