    摘要: Photoelectric detector fitted with an optical unit having lenses focused along optical axes of transmitting and receiving components 15, 16 and with an electronic circuit 14 on one edge of which are fixed the components. A reflection head 30 is fixed in sealed manner to body 10 of the detector, said head comprising a prism preferably with total reflection 32 inserted into hood 31 with an air space maintained between reflection surface 32a of the prism and front surface 31a of the hood.
