Sensors on IO-Link Can Enable the Connected Enterprise

Watch how smart sensors with IO-Link can enable smart machines for The Connected Enterprise.

IO-Link Technology

IO-Link Technology is a worldwide open-standard protocol that integrates sensors into our Connected Enterprise by connecting the IO-Link enabled device into an IO-Link master module. You can deliver data from the sensor directly into a control system in a very efficient manner. The flexibility of IO-Link capable sensors allows machines to operate more effectively by providing the controller with diagnostics. In addition to product detection, sensors provide detailed and accurate machine health status to improve uptime.
