Why Holistic Encoders are More Accurate

All absolute rotary encoders have a rotor which is attached to the rotating shaft and a stator which is attached to the housing holding the shaft. The interaction of these two components produces a measure of the shafts rotational angle. The most important parameters of absolute rotary sensors are resolution, accuracy and tolerance to misalignment of the rotational axes.

Custom-Off-The-Shelf: The New ‘COTS’ Goods

For decades there has been an initiative to source COTS (Commercial-off-the-shelf) goods when possible, and for good reason. COTS goods generally are less expensive, more readily available and easier to dual source.

Introduction to Intrinsically Safe Sensors

Intrinsically safe (IS) sensors are unable to produce a spark strong enough to cause ignition. Learn how this is accomplished and design considerations when using IS sensors.

Wiegand Effect Energy Harvesting

The “Wiegand effect” was discovered almost fifty years ago and has been used successfully in several specialized applications. However, its full potential for energy harvesting and signal generation has received only limited recognition. With recent enhancements to the energy output from Wiegand devices and the emergence of a new generation of ultra-efficient electronic chips for wireless communications, the technology is showing significant promise, especially in the exciting new area of the Internet of Things (IoT). UBITO, a member of the FRABA Group of technology companies, is leading research and development projects aimed at fulfilling this promise.
