Photoelectrics
Retro-reflective, Polarized
Type EP 5520
The EP 5520 is a family of
inexpensive general purpose
polarized retro-reflective sen-
sors in a flat-pack housing.
The size (W x H x D) is 35 x
55 x 15 cm, made in grey
PC/ABS, is ideal for use
where the space is limited.
Easy mounting with only two
M4 screws. The output is a
4-wire complementary (NO
and NC) output in NPN (cur-
rent sinking) or PNP (current
sourcing).

Installation Hints
Relief of cable strain Protection of the sensing face Switch mounted on mobile carrierTo 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
