ifm offers draw wires for distance measurement
ifm electronic is now offering a range of draw-wire mechanisms that, it says, provide a simple, reliable and accurate way of measuring position and distance over long straight spans.
“Featuring robust construction that ensures reliable operation in demanding environments, even when the draw wire is subjected to continuous strain, the new E614xx mechanisms are suitable for use with almost any encoder that has a 58 mm synchro flange and a 6 mm shaft.”
Typical applications include monitoring the height of fork-lift truck forks, the extension of crane booms and the vertical position of trolleys in high-bay warehouses. Essentially, the wire-draw mechanisms comprise a housing containing a spool of wire cable, the end of which is attached to the target object.
Position of target evaluated
As the target moves, the spool rotates and this rotation is captured by the encoder that has been attached to the mechanism, allowing position of the target to be evaluated.
“Ifm draw wire encoders have high shock and vibration resistance, thanks to their magnetic sensing principle and can be used in harsh environments where alternative technologies might struggle.”
ifm is currently offering the draw-wire mechanisms in four versions:
Special versions for spans up to a maximum of 15 m can be supplied upon request.
