Product Description
A family of inexpensive gen-
eral purpose inductive prox-
imity switches in industrial
standard nickel-plated brass
housings. M12, M18 and
M30 types. They are able to
handle simple applications
where a basic sensor pro-
vides adequate sensing per-
formance. Output are open
collector NPN or PNP tran-
sistors. Available with cable
and M12 plug.

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
