Introducing GMR Precision Switching Sensors for Airpel® 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 Accurate
Feedback Every Time.
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 sensors some important advantages over other types of sensors:
•
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 switching signal.
Installation is Easy, Secure and
User Friendly, too. The Sick, Inc. GMR sensor is specially shaped to allow for easy installation in our T-slot aluminum 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 when ready 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 versatile 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.
