Accuracy, Resolution and Repeatability

There are several key terms that are critical to specifying the optimal position sensor for a given application. This application note defines these key terms and how they relate to the sensor’s role in the overall system performance. It is important to consider that precision is very much a system issue and can be dominated by mechanical errors such as eccentricity. This paper discusses the most significant mechanical error for rotary applications (eccentricity) and presents eccentricity tolerant position sensor solutions.

TMR: A New Revolution in Magnetic Rotary Encoders

Abstract: Tunnel magnetoresistance (TMR) sensing is an exciting new chapter for magnetic-based rotary encoders. Requiring less current, while offering higher signal strength, many of the inherent short comings of Hall Effect based sensors can be addressed.

Application Note: Ethernet Protocols for Industrial Automation Sensors

Industrial Ethernet protocols are playing a growing role in automation, as they offer a number of advantages over traditional fieldbus protocols such as CANopen and PROFIBUS. Industrial Ethernet protocols are based on standard Ethernet technology, which provides a number of benefits, including:
