Linear Positioning Breakthrough - First Non-Contact Transducer to Match Wear-Prone Linear Pots in Form Factor and Cost

Patented new technology in Micropulse BIW renders linear pots obsolete, provides drop-in fit and low cost

FLORENCE, KY (October 2005): Balluff's patented new Micropulse(TM) BIW transducer is a first in linear positioning technology, offering superior non-contact positioning accuracy in a form factor matching a linear pot, with a price that's comparable. The Micropulse BIW uses all-new, patented, pulsed-inductive technology to provide superior performance and reliability with a non-contact design that allows drop-in-fit replacement for pots. The BIW's wear-free, non-contact design completely eliminates performance degradation over time, the principal cause of downtime and loss of accuracy in pots. The new design is ideal for any application where old-style linear pots are used, such as plastic injection molding machines, blow molding machines, stamping presses, woodworking machinery, and hydraulic motion bases - anywhere linear motion must be monitored and/or controlled.

"Wear-prone linear pots have long been trouble spots in terms of reliability, accuracy, and performance," says Balluff Transducer Product Specialist Scott Rosenberger. "Their popularity is driven by simplicity and low-cost. Wear-free, non-contact transducers have been available for linear position feedback, but higher cost and different form factor have impeded widespread adoption. The BIW solves these problems by providing clearly superior performance, drop-in mechanical compatibility, and a price comparable to resistive linear pots. It's a breakthrough new product that will solve many application problems."

The Micropulse BIW is available with an analog 0 to 10V or -10 to +10V output. It has a super-fast >20 kHz update rate, non-linearity of ±0.02%, and resolution down to 5 microns. It is immune to external EMI and available in stroke lengths from 75 mm to 750 mm.
