An Introduction to non-contact position sensors

Non-contact position sensors are used in many different ways, some even in unexpected ways. For instance, they are used in amusement parks, particularly rides that require rising and falling action. The rides usually move up and down on hydraulic cylinders that are controlled by encoders that detect their position at a particular point in time. The sensors also come into play when the rides are finished, as they need to go back to a position where riders can safely embark.

In other industries where there is a lot of vibration, heat, noise, and dirt, these kinds of sensors are also very useful. In offshore oil rigs, for instance, these contactless sensors should be able to tolerate constant vibration and other contaminants in the oil and gas industry.

With all the practical uses of non-contact position sensors, they are actually advantageous because they will have minimal wear and tear. They usually have very low weight and offer high resolution and precision.

Netzer Precision manufactures an entire product line of non-contact position encoders that meet industry requirements. Originally built by its founder to withstand extreme conditions, the way that their encoders are originally designed meets the demands of critical applications amidst challenging environments. These types of sensors have non-contact displacement sensing over small ranges with high resolutions. Allowable mounting eccentricity is +-0.1mm and allowable rotor axial motion is +-0.1mm.
