IOlink sensors


IO-Link_technology_800x600

Most sensors and actuators today are already equipped with microprocessors, which can be used for parameterization, storing configuration data, and controlling indication. The obvious next step is to overcome the bottleneck of the binary standard interface and make additional functions centrally accessible for the automation system.
IO-Link is based on a point-to-point connection between the sensor/actuator and an interface module. Up to now, the binary connection was only designed for transferring switching information, but IO-Link now allows two bytes to be transferred normally in a 2 ms cycle via a combined switching status and data channel. Other information can be exchanged in addition to the process values, such as parameters or diagnostics messages. This enables communication with sensors and actuators down to the “last meter” to be established for universal communication.

Q4X laser sensor

Rugged design resists mechanical impact, over tightening and extreme vibration
Clear distance readout from angled four-digit display



BCT capacitive sensors

The intelligent interface makes the proximity switch a universal sensor that can be parameterized to suit over 100,000 individual requirements. For example, the two separately adjustable switching distances (each either NC or NO, as well as PNP or NPN) enable early warning functions to be set for targets subject to wear. The user can thus take action already before a failure occurs. Various timer functions can also be set, for example an off-delay for speed monitoring. These options are already possible in I/O mode, in which the sensor can be operated on a conventional digital input.

Uprox 3 inductive sensors

Turck is now offering its flagship uprox3 sensor also in an IO-Link-capable version. The intelligent interface makes the factor 1 inductive proximity switch a universal sensor that can be parameterized to suit over 100,000 individual requirements. For example, the two separately adjustable switching distances (each either NC or NO, as well as PNP or NPN) enable early warning functions to be set for targets subject to wear. The user can thus take action already before a failure occurs. Various timer functions can also be set, for example an off-delay for speed monitoring.
