Cylinders
Airpot Corporation offers non-contact electronic switching sensors from Sick, Inc. using state-of-the-art GMR technology. These are the most precise and accurate magnetically activated cylinder sensors on the market.
You’re Assured Safe and AccurateFeedback Every Time. Installation is Easy, Secure and User Friendly, too.
A magnetic field has secondary maximum lev-els that can cause double switching behavior
in Hall effect and reed sensors. But GMR
(Giant Magneto Resistive) technology is based
on the measurement of the average strength of
the magnetic field. This gives GMR sensors
some important advantages over other types
of sensors: The Sick, Inc. GMR sensor is specially shapedto allow for easy installation in our T-slot alu-
minum track. The track comes permanently
bonded along the entire length of the
cylinder
in the location you specify when ordering
sensor-ready Airpels.The sensors are sold separately and whenready to be installed, can be slid into the
track through the end of the slot or simply
angled into the slot at any point along the top
of the track. Turning a screw in the sensor
tightens it securely against the track. This ver-
satile installation allows for easy mounting
and positioning of the sensor at any time,
even if the
cylinder has been installed close to
obstructions near the ends of the
cylinder. In
addition, the sensor’s tightening screw and
epoxy bonded track avoid the vulnerabilities
common to typical mounting straps and
clamps when subjected to vibration, shock, or
extreme thermal changes. GMR sensors greatly reduce the potential for troublesome double switching, ensuring better accuracy. GMR sensors do not need to be adjusted to magnetic field polarity.
Compact Profile
The GMR sensor chip is encased in a small,
rugged plastic shell. The entire sensor can fit
in a common soda straw less then 1.25 inches
long. There is a small LED window in the
shell to allow visible indication of the switch-
ing signal.
