Sensor Applications
Sensing Solutions Summary
Small Parts Detection
Small objects moving through
a “curtain-of-light” are
counted by detecting a
change in reflected light. A
low contrast logic module
inside the control unit
responds to slight but abrupt
signal variations while
ignoring slow changes such
as dust build-up.
Parts Detection
A four inch Perfect Prox
sensor detects parts of
various heights from 0.5 to 3
inches passing through a
channel, while ignoring the
channel bottom.
Filter Paper Length Control
A focused diffuse reflective
sensor interfaces with a
programmable controller to
measure a specific length of
corrugated automotive filter
paper. The control detects
the presence or absence of a
corrugation. When a
predetermined number of
corrugations has been
detected, the programmable
controller directs a shear to
cut the paper.
Over/Underspeed Control
A reflex sensor with a motion
detection module counts the
revolutions of the wheel.
Speed is controlled by a
programmable controller.
Provides timing ranges from
2.4 to 12,000 counts per
minute.
Multi-Hole Casting
Inspection
Remote sensors inspect for
the presence of holes in a
metal casting. Because each
hole has its own inspection
system, accurate defect
information is recorded.
Rugged sensor housing and
extremely high signal
strength handle dirt and
grease with minimum
maintenance. Using the
modular control unit allows
for dense packaging in small
enclosures.
Broken Thread Detection
A pair of remote thru-beam
sensors scan over and under
multiple strands of thread. If a
thread breaks and passes
through one of the beams,
the low-contrast logic module
detects the sudden change in
signal strength and energizes
the output. Because this logic
module does not react to
slow changes in signal
strength, it can operate in a
dusty environment with little
maintenance.
