CARLO GAVAZZI Power Supplies Installation Hints To avoid interference from inductive voltage/ current peaks, separate the prox. switch pow- er cables from any other power cables, e.g. motor, contactor or solenoid cables Relief of cable strain The cable should not be pulled Protection of the sensing face A proximity switch should not serve as mechanical stop Switch mounted on mobile carrier cable should be avoided Specifications are subject to change without notice (04.05.10)
