3.0 PRODUCT DESCRIPTION
3.1 Short description
CR0 light curtains are photoelectric devices built according to the IEC 6049 -5-2 norms and they must not be considered as safety
devices. Therefore they must not be used to guarantee operators’ safety nor to protect users on dangerous machines. They must
rather be used to detect objects reducing or obscuring the intensity of light beams that returns from the reflector.
The housing is in aluminium painted in blue RAL5002, size 20x36mm, (20 mm refers to the front side). A groove on the back allo s
connection ith T-shaped components. The top and bottom side are in black PBT, the optical indo is in PMMA. Protection degree
is IP6 .
In all models of the series, CR0 have t o LEDs indicators: Red and Green in combination, indicate the states of the sensor
(alignment, state optics and fault indication), they are arranged at the top of the curtain, the light is intense and diffused in all
directions, this ensures a great visibility in all conditions.
All models in the CR0 have an optic composed of a continuous array of 9x9mm lenses ith a step of 10mm, CR0 have seven
lenses. The optical indo has a height of 69mm; the total height of the curtain is 10 mm.
Emitter and Receiver are alternate ith the follo ing sequence is: E1, R1, E2, R2, E3, R3, E4 ith reference the cable side. This
allo s to realize a continuous succession of six pairs of reflex elements; the emitted light is polarized and has a ave length of
61 nm.
The orking distance is 0.2...5m ith reflector RL106 and lo er ith smaller reflectors, the best detection capability is 6mm.
All models of CR0 series have a teach button (inductive teach could also be available) in the top of the curtain dedicated to the
activation of menu functions: t o levels of Teach-in and Blanking.
The Teach_G (gross teach) select an excess gain equal to 2 times the threshold, the Teach_F (fine teach) select an excess gain
equal to 1.2 times the threshold; the latter should be used only if the system and the environment in hich the product is used are
clean and ith an high mechanical stability.
The sensor does not use automatic systems of signal tracking, but its repeatability is based on a sophisticated control of thermal drift.
The Blanking of the beams, allo s gradually eliminate pairs of beams; the active couples (E+R) may range from a maximum of six to
a minimum of one.
This sensors has a standard output ith M12 male flying connector (240 mm pigtail).
The CR0 models have four interface circuits hich can be combined in different ays depending on the model and the number of
output cables:
a) Supply 15...30V
b) IO_Link output (C/Q), PNP/NPN/PUSH- PULL
c) Auxiliary output (Q): PNP/NPN/PUSH- PULL
d) Auxiliary input, output mode selection LIGHT/DARK (NC/NO) or more.
