The
JUTAI
High-Performance
Vehicle
Loop
Detector
is
engineered
to
deliver
unmatched
speed
and
reliability
in
vehicle
detection,
designed
for
demanding
environments
such
as
toll
lanes,
industrial
gates,
and
urban
intersections.
Featuring
a
rapid
response
time
of
≤15ms,
it
ensures
instantaneous
triggering
of
barriers
or
traffic
signals,
eliminating
delays
in
high-traffic
scenarios.
With
16-level
sensitivity
adjustment
(0-F),
the
detector
precisely
identifies
vehicles
ranging
from
motorcycles
to
heavy
trucks
(20–2000μH
inductance
range),
while
its
adaptive
frequency
adjustment
(40–80KHz)
blocks
interference
from
adjacent
detectors,
EV
chargers,
or
power
lines.
The
IP67-rated
aluminum
housing
provides
robust
protection
against
dust,
water
ingress,
and
extreme
temperatures
(-40°C
to
+70°C),
ensuring
reliable
operation
in
harsh
outdoor
or
industrial
settings.
Ideal
for
smart
city
infrastructure
and
logistics
hubs,
this
detector
excels
in
diverse
applications.
In
highway
toll
systems,
its
fast
response
prevents
revenue
loss
from
undetected
vehicles,
while
warehouse
door
control
benefits
from
its
immunity
to
electromagnetic
noise
generated
by
forklifts
or
automated
guided
vehicles
(AGVs).
The
universal
12-24V
DC/100-240V
AC
input
supports
solar-powered
and
grid-connected
installations,
and
the
SPDT
relay
output
(0.5A
@
120VAC)
ensures
seamless
integration
with
traffic
controllers,
barriers,
and
IoT
platforms.
A
recent
deployment
at
a
Middle
Eastern
port
reduced
gate
congestion
by
25%
through
precise
truck
detection
and
rapid
gate
cycling.
Certified
for
CE
and
FCC,
it
also
complies
with
RoHS
environmental
standards,
making
it
a
sustainable
choice
for
modern
infrastructure.
JUTAI’s
detector
stands
out
with
plug-and-play
installation
and
DIN-rail
mounting,
cutting
setup
time
to
under
20
minutes.
The
auto-reset
function
recovers
automatically
from
power
surges
or
transient
faults,
minimizing
downtime.
For
parking
management,
its
adjustable
sensitivity
eliminates
false
triggers
from
shopping
carts
or
debris,
and
the
5-year
warranty
underscores
its
durability.
Trusted
globally
in
airports,
smart
cities,
and
industrial
parks,
the
JUTAI
High-Performance
Detector
redefines
efficiency—where
speed,
precision,
and
ruggedness
converge.

Used
to
avoid
the
interference
-
In
the
application,
where
two
or
more
loop
detectors
and
sensing
loops
have
been
installed,
set
one
detector
to
high
frequency
and
the
other
set
to
low
frequency
to
minimize
the
effects
of
cross-talk
between
the
two
systems(The
sensing
loops
and
detectors
should
be
positioned
at
least
2m
apart).

Detector
Position
And
Installation:
-
Install
the
detector
in
a
weatherproof
housing.
-
The
detector
should
be
as
close
to
the
sensing
loop
as
possible.
-
The
detector
should
always
be
installed
away
from
strong
magnetic
fields.
-
Avoid
running
high
voltage
wires
near
the
loop
detectors.
-
Do
not
install
the
detector
on
vibrating
objects.
-
When
the
control
box
is
installed
within
10
metres
of
the
loop,
normal
wires
can
be
used
to
connect
the
control
box
to
the
loop.
More
than
10
metres
requires
the
use
of
a
2
core
shielded
cable.
Do
not
exceed
30
metres
distance
between
control
box
and
loop.
Loop
Installation:
The
loops
are
sealed
using
a
“quick-set”
black
epoxy
compound
or
hot
bitumen
mastic
to
blend
with
the
roadway
surface.
