A
magnetic
loop
detector
detects
vehicles
that
are
within
proximity
to
the
gate.
A
magnetic
loop
detector
can
be
used
to
open
the
gate
when
a
car
pulls
up
either
from
the
inside
or
the
outside
depending
on
which
side
of
the
gate
you
install
it.
A
magnetic
loop
is
usually
buried
under
the
ground,
and
the

run
to
the
gate
opener
control
board.
Magnetic

usually
require
DC
power,
using
the

terminals.
Connect
the

and
the
