Position Feedback System from Pepperl+Fuchs
October 9, 2011
The PosiTrack PCV from Pepperl + Fuchs Inc., Twinsburg, OH, is a 2D, camera-based position feedback system uses data matrix technology to solve linear feedback applications common to automated storage and retrieval systems, overhead monorails, lifts, and rotary turntables. The system can handle read speeds to 41 fps. Thin strips of adhesive-backed data matrix codes are placed along a carrier's travel path to continuously update its movement with ±0.1 mm resolution. Scanner-to-code-band separation up to 80 mm is typical while the axial movement tolerance is ±15 mm. The touchfree optical technology provides low-maintenance operation.
