IO-Link Interface Opens Up New Possibilities in The Field of Inductive Positioning Systems

Inductive positioning systems operate contact-free using an inductive sensor and a damping element. There is no need for a special target—a steel target or a machine part itself can be used instead. This saves effort, time, and costs.
Typically, positioning systems are used in machine tools, e.g., for spindle production, but also in printing and paper industry applications or for packaging and filling cycle control. Reliable functionality of the positioning system is guaranteed even under harsh conditions: Since it is independent of the distance, exact measurements are achieved within the tolerance range—even under strong vibrations. Due to ATEX certification for Zone 2/22 or Division 2, these positioning systems can operate in explosion-hazardous areas.

Available in 40 mm, 80 mm, and 120 mm lengths, the positioning system PMI F90 stands out with a broad range of functions. The cost-efficient PMI F90 performs both the measuring and the switching function. Two damping elements can also be detected simultaneously, leading to straightforward installation. The PMI F90 comes with a data storage function that ensures automatic new parameter settings when replacing the sensor.

Since both positioning systems PMI 90 and PMI F112 include an IO-Link interface, it is easy to determine whether the target is outside the measuring range, or whether the signal quality is optimal. The interface can be parameterized to customer specifications and is adaptable to the specific application demands. All event logs can be retrieved during operation, and alarms are automatically sent to the control unit. Additional information about the device status or the current operating hours can be accessed via IO-Link master. This enables a consistent diagnostic function based on the condition data provided—condition monitoring—and allows a timely introduction of corresponding measures in terms of predictive maintenance.
