Photoreceptor circuit provided with a component, the photoreceptor surface comprising a first area able to operate in reflex mode and a second area with analog detection of position able to operate in proximity mode. The first area Z1 is a photodiode area with an output Al and the second area Z2 is a PSD type area provided with a close output A2 and a remote output A3, wherein a switch I1 connects either the A1 output in reflex mode or output A2 in proximity mode, to a processing circuit 12.
