Product Description
AC proximity switches con-
structed in rugged thermo-
plastic polyester housings.
Sizes available are M18 and
M30. Length of housing is
selectable with 30 mm
thread or 50 mm thread.
Bright LED ring utilizing a
yellow LED clearly gives
indication of output status.
Protection rating IP 67
ensures environmental com-
patibility.

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
Protection of the sensing face
Switch mounted on mobile carrier
Incorrect
Correct
The cable should not be pulled
A proximity switch should not serve as
mechanical stop
Any repetitive flexing of the
cable should be avoided
