Sub-millimeter Position Feedback

July 1, 2006
The SCS2A/WCS3A PosiTrack Position System is designed to bring fraction-of-a-millimeter position feedback to applications such as overhead monorails, gantry cranes, warehouse automation, galvanizing processes and conveyors.

PosiTrack consists of three basic components: a U-shaped read head; code rail and support hardware; and network and control interfaces. The read head optically scans a uniquely coded rail to determine a carrier mechanism’s position. An internal microprocessor translates a 48 sender/receiver LED array status into a 19-bit code, providing 0.8mm positional resolution over travel distances to 1,070 feet. Rail heads require no calibration, and sophisticated intelligence provides highly reliable data in challenging conditions, says the vendor.
