To avoid interference from inductive voltage/ Relief of cable strain Protection of the sensing face Switch mounted on mobile carrier
current peaks, separate the prox. switch pow-
er cables from any other power cables, e.g.
motor, contactor or solenoid cables
Incorrect
Correct
The cable should not be pulled A proximity switch should not serve as Any repetitive flexing of the
mechanical stop cable should be avoided
