Abstract: An actuating device for a sanitary fitting comprising a housing (2) having a front side (13) and a rear side (14) and also a detection sensor (3) having a transmitter (4) and a receiver (5) for detecting a user, wherein the detection sensor (3) emits waves via the transmitter (4) and receives them via the receiver (5). The detection sensor (3) is arranged in a cavity (6) that has a radiating region (7a), which is transparent to said waves, in the direction of said waves; and wherein the housing (2) is designed such that it is installable having a gap (7b) in relation to a predefined installation plane (ME) on the structure side, which gap (7b) is located in relation to said radiating region (7a) such that the emitted waves and also the waves to be received are guided through the gap (7b).
