IO-Link is the first standardized IO technology worldwide (IEC 61131-9) for the communication with sensors and also actuators. The powerful point-to-point communication is based on the long established 3-wire sensor and actuator connection without additional requirements regarding the cable material. So, IO-Link 

Is no fieldbus but the further development of the existing tried-and-tested connection technology for sensors and actuators.

ema is a leading manufacturer in design, produce and sales of sensor technology and industrial controllers. With the development of "industry 4.0", the intelligent transformation of manufacturing industry has become a trend. As a two-way communication interface technology, IO-Link can expand the diagnosis of sensors and actuators, or set simple and fast parameters, which can reduce costs and improve efficiency. In the future, ema will develop products that support IO-Link functions, based on the leading company of IO-Link, provide timely and convenient solutions and also the service for the customers all over the world by continuously optimizing product performance.
