Which Positioning Sensor Is Right for My Application?

How to make sense of the many options available for ensuring accuracy

By Mike Bacidore

Our metal stamping machines need to be able to run a variety of parts through the press. Any errors in the coil-change process can be costly. The manual changeover itself is time-consuming, but a damaged press means expensive repairs and lost production. We need continuous position sensing, but our machines typically operate in harsh environments, and sometimes vibration and magnetic fields can be an issue. There are so many potential positioning-sensor solutions. What’s the difference? Any advice on where to start?
