Optical switch with display function has light transmitter(s)/receiver(s), operating state indicator(s), LED(s) with control circuit(s) with operating state/signal output/photo detection read-out stages, signal analysis circuit, mode switch

摘要

The device has at least one light transmitter, at least one light receiver and at least one operating state indicator, whereby at least one light emitting diode (2) is provided that is controlled by at least one control circuit (11) containing an operating state output stage (4), a signal output stage (5), a photo detection read-out stage (6), a signal analysis circuit (7) and a periodically clocked operating mode changeover switch (3). An independent claim is also included for an optoelectronic sensor with an inventive device.
