Ordering KeyProduct Description
The PMP12RS is a powerfull
polarized retro reflective sensor. The sensor is designed
for the industrial door market.
The sensor is made in a strong
glass reinforced PC/ABS housing. The long sensing distance
of 12 m makes the sensor usefull in applications where dust
and weather conditions will
influence on the sensing performance. The sensor fulfills
the positive safety standards,
NF P25-362, NF P25-363.

Mode of Operation
The red light beam from the
emitter (3), is generated from
the mod u la tor (5), col li mated in the lens (2) and po larized in the polarizor (1). The
light beam is re turned by a
triple reflector and pass es a
sec ond polarizing filter (1) and

the receiver lens (2) before
reaching the de tec tor element
(4).
The received signal is amplified by the amplifier (6), and
the modulated impulses are
synchronized and detected
in the pulse detector (7). The
modulated impulses are
re cog nized in the demodulator (9).
The output signal from the
demodulator controls 2 re lays
(10 and 11) which are con-
nec-ted in the manner prescribed by the NF P25-362
standard. The centre of the
two relay contacts is avail a ble
as a check point for check ing
each con tact in di vid u al ly.
General Information about the Polarization Principle
To avoid false output signals from targets with highly
re flec tive surfaces, a retro-reflec tive photoelectric switch
can be equipped with polarizing filters (anti-glare filters).
In this case the emitted light
first passes through a vertical
polarizing filter. The triple reflector turns the po lar i za tion
90 degrees and reflects the
beam. The 90 degree turned
reflected light then passes a second polarizing filter
which enables only horizon-
tally po lar ized light to pass.
In this way, only the light
whose po lar i za tion plane has
been turned 90° by the triple
reflector will reach the re ceiver ele-ment. Since usual surfaces do not depolarize the

light, the beam reflected by a
shiny tar get will not be recog nized as a reflector and the
switch ing el e ment will therefore only change state when
receiving the re flec tor sig nal.
