Sensors & transducers


Numerous industries are embracing the ‘4.0’ paradigm, which frames the adoption of various digital technologies as a fourth industrial revolution. Alongside these new concepts sits an evolution of the robotics that underpinned Industry 3.0: an advancement of seemingly mature technologies to serve us for the coming decades. Part of this advancement is facilitated by next generation position sensors employing Application Specific Integrated Circuits (ASICs). Here, Dr Mike Coulson, analogue design manager at ASIC design and supply company Swindon Silicon Systems, explains how custom ICs for position sensors are helping to deliver speed, accuracy and cost savings to industrial automation.


of manufacturing to be accomplished, and gives rise to products that outperform and outlast their precursors. Speed equates to higher throughput, and reduced part cost. Such machinery may be driven by electromagnetic, pneumatic or hydraulic means - but will invariably be under the control of an electronic system that governs its motion. A key part of these systems are the position sensors that detect the state of each moving component. ‘Position sensor’ is a broad term covering a
