Wiring diagram

Functional principle

The weld sensors are available in different
versions, with different signal intensities
and diameters. Ferromagnetic parts which
differ strongly in their material properties and
diameters can thus be detected. A target part
has to be located within the so called sensitive
area in order to be detected. The internal
sensor signal reaches the maximum intensity if
the sensitive area is completely covered by the
target. Partial coverage is also possible.



Sensitive area S = 9 mm
Within this area the sensor signal changes
when components are connected.



Maximum range M = 13 mm
In case of complete coverage of the sensitive
area the maximum signal intensity is achieved.

Mounting instructions

Mounting instructions/Description

The magnetic field sensor is especially suited
for the detection of welding nuts as well as
spacer or reinforcing sleeves. The parts to be
detected must always consist of ferromagnetic
material, so that a proper function can be
guaranteed. Most applications need center
bolts to tack the welding nuts and reinforcing
sleeves in place and thus provide mechanical
protection of the sensors. Theses bolts have
to be made of non-ferromagnetic material, like
stainless steel for example. Center bolts are
not available at Turck, as these have to be
individually produced for and adjusted to the
correspondent application.



The welding nut sensor detects ferritic targets
with diameters between 6mm and 12mm.
