Product Description
Miniature inductive proximity
sensor available as Ø 4 and
5 x 5 mm types. Output con-
figuration for NPN/PNP with
both NO and NC types as
standard. Housing materials
are stainless steel for Ø 4 and
aluminium for the 5 x 5 mm
type. Cabled models utilise 2
meters of PUR cable and
plug versions features a
bright ring LED.

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
