Introducing GMR Precision Switching for Airpel Cylinders
2Pages

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 sensors 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. > 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. > Airpot Ү and Airpel are registered trademarks of Airpot Corporation.
