Product Description
Miniature inductive proximity
sensor available as 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 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
Relief of cable strain
Protection of the sensing face
Switch mounted on mobile carrier
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
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
