Smart Sensors by SICK

Networked production and control processes in complex machine environments determine the industrial future and make Industry 4.0 possible in the first place. Smart Sensors already today support dynamic, real-time-optimized, and self-organized industry processes. They record real operational statuses, turn these into digital data, and share them automatically with the process controller. The added value of sensor communication depends significantly on the quality and reliability of the delivered data. In order to create the best possible basis for a future-oriented automation system, SICK has equipped its Smart Sensors with four special properties.

Four dimensions of Smart Sensor technology

Smart Sensors generate and receive data and information which goes beyond traditional switching signals or measured process parameters. They therefore enable substantial increases in efficiency, more flexibility, and better planning security for predictive plant maintenance. Depending on the requirement, Smart Sensors cover up to four dimensions of Smart Sensor technology.


Enhanced Sensing

The highest possible level of reliability during object detection and recording of measured values is the basis for every Smart Sensor. Benefit from our experience spanning over 70 years in the development and application of groundbreaking sensor technology.

Enhanced Sensing provides you with reliable detection and measurement results, which have a direct impact on your plant availability.

Efficient Communication

With superordinate control systems, Smart Sensors communicate via IO-Link: The reliable communication channel, which is used across the globe for sensors and actuators at field level, offers many practical advantages in day-to-day industrial operation. Plug and play thus becomes a reality in your plants.

Smart Tasks

Smart Tasks offer intelligent additional sensor functions on the one hand, and direct networking of multiple sensors on the other in order to manage partial applications faster, more efficiently, and more cost-effectively. Smart Tasks increase the efficiency in your processes: They deliver just the right information at just the right time to your plant process.
