Airpel Sensors
Airpot GMR sensors make possible the addition of a position sensing option to our popular line of Airpel non-stiction air cylinder actuators. We offer non-contact electronic switching position sensors from Sick, Inc. using state-of-the-art GMR technology. These are the most precise and accurate magnetically activated pneumatic cylinder sensors on the market. The addition of GMR sensing technology to the Airpel non-stiction cylinder line offers OEM designers an easy-to-install, secure, and reliable position switching solution. The pneumatic cylinder sensors operate at 10-30 V DC and have repeatability of less than or equal to 0.2 mm.
With GMR sensors, OEM designers are assured safe and accurate feedback. A magnetic field has secondary maximum levels 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 pneumatic cylinder sensors some important advantages over other types of position sensors. GMR sensors greatly reduce the potential for troublesome double switching, ensuring better accuracy, and they do not need to be adjusted to magnetic field polarity.
With its compact profile, the GMR position sensor chip is encased in a small, rugged plastic shell. The entire sensor can fit in a common soda straw less than 1.25 inches long. There is a small LED window in the shell to allow visible indication of the switching signal. Because the Sick, Inc. GMR sensor is shaped to allow for quick installation in a specially designed T-slot aluminum track, installation is easy, secure and user friendly. For customers desiring electrical output of piston position, most Airpel models are offered with an optional switch-activating magnet on the piston, as well as one or more of the aluminum tracks which measure 9.51 mm wide and 6.83 mm high, and come permanently bonded along the entire length of the cylinder in the location desired when ordering sensor-ready Airpels.
Airpot offers the Sick, Inc GMR position sensors separately and we stock popular models with PNP or NPN output, along with matching accessory extension cables available in 2 and 5 meter lengths.
