Abstract

A circuit arrangement for contactless controlling of a sanitary fitting comprises a transmitter (1) which, controlled by a clock generator (5), emits radiation pulses with the clock frequency of the latter. The radiation reflected by an object (2) in a monitoring area passes to a receiver (3). The output signals of the receiver (3) are counted in a logic control circuit (9). If the number Nz determined during this counting over a certain number N of clock pulses of the clock generator (5) exceeds a number N1 stored in a first memory (10), the logic control circuit (9) generates at an output (A) a signal which opens the solenoid valve (4) of the sanitary fitting. If after generating an output signal at the output A of the logic control circuit during the counting of the output pulses of the receiver (3) over N clock pulses a number Nz is established which is less than a number N2 stored in a second memory (11), the logic control circuit (9) provides at a second output (B) an output signal which re-closes the solenoid valve (4). <IMAGE>
