Pepperl+Fuchs launches a new flexible and efficient PMI induction positioning system

Pepperl+Fuchs, as a pioneer in the field of sensor technology, continuously improves products and provides new applications in response to customer needs. Recently, Pepperl+Fuchs launched an innovative product-PMI inductive positioning system.

PMI inductive positioning system introduction:

This system has comprehensive functions, paving the way for modern Industry 4.0 applications: the positioning system is equipped with an IO-Link interface, which can be used for user-specific parameter settings, so users can detect and evaluate additional status information. PMI inductive positioning technology combines the robustness of inductive proximity sensors with the high accuracy of position measurement and angular positioning systems. The simple use of steel actuators is designed to maximize application flexibility. Pepperl+Fuchs continues to develop and improve this non-contact, wear-free technology. With the highest quality standards and the richest experience in the market, we provide a comprehensive range of inductive positioning systems.

The advantages of PMI inductive positioning system at a glance

1. Adopt non-contact, maintenance-free technology and high environmental protection to ensure maximum durability

2. Using a simple steel actuator opens up various possible applications

3. Flexible with various functions, programmable measurement and switch range

4. Various housing designs: from compact machine tool design (14 mm measuring length) to heavy machine design (960 mm measuring length)

5. Strong anti-noise ability to ensure the reliability of the process

6. Integration of measurement and switch functions to improve efficiency

The PMI inductive positioning system is suitable for detecting linear position changes or measuring rotation angles. Reliable detection can be achieved even in dusty and oily environments or extreme temperature fluctuations.

Highest accuracy and maximum efficiency

The patented configuration and wiring of multiple coils in a single sensor, as well as intelligent evaluation, can achieve the highest accuracy and maximum efficiency. Using a simple steel actuator, whether the actuator is designed by the customer, Pepperl+Fuchs's proprietary accessory, or a part of the machine being inspected-the PMI inductive positioning system can detect the precise position.

Use one sensor for measurement and switching functions

According to application requirements, only one sensor is needed to define the measuring range and multiple switching points or windows. The PMI sensor is used as a position sensor and limit switch at the same time. In other solutions that require multiple sensors, only one device is needed here.

Sensorik4.0®--paving the way for the smart factory

The PMI induction positioning system is equipped with IO-Link, paving the way for the fourth industrial revolution. In the future of Industry 4.0 with a fully networked production system, sensors for communication play a vital role: send and receive sensor data during the production process, and receive higher-level local or cloud-based information systems.

IO-Link opens up new possibilities

Direct communication at the sensor level/execution level, customized parameterization for customers, and access to valuable additional information: the IO-Link interface opens up new possibilities for position detection. In addition to process data, value-added data such as signal quality or operating hours can also be accessed directly from the sensor.

Through an accurate event log, you can determine how often the target leaves the measurement range and draw direct conclusions about mechanical tolerances, wear levels, or setup errors. In this way, event-oriented maintenance can be obtained-this concept is fully in line with Industry 4.0.

Paving the way for Industry 4.0, Pepperl+Fuchs is providing Sensorik4.0® with innovative sensor technology, using standard IO-Link interfaces to support the digitization of industrial applications.

Reliable process application examples

Control the guide roller system in the packaging machine, monitor whether the cylinder is clamped or provide valve position feedback in hazardous locations-the multifunctional F90 series is suitable for various applications.

Efficient guide roller control

During the winding and unwinding process in the packaging industry, the tearing or sagging of paper or film must be prevented. Guide rollers, known as "guide devices", are constantly adapted to the speed of machine operation to ensure reliable material feeding.

The F90 series reliably detects the position of the guide roller and realizes its own precise control. By combining measurement and switching functions in one device, two switching points or windows are defined at the same time. In this way, not only the position of the guide roller can be used as an analog value, but also the two limit switch positions can be used as a switch signal from a single device. The guide roller system can be controlled efficiently without additional sensors.

Safe use in hazardous locations

The F90 series can be quickly and easily installed on pneumatic diaphragm valves or linear control valves, and provide continuous position feedback, providing an ideal solution for accurate valve position detection. The certified version makes the system suitable for hazardous locations in ATEX Zone 2/22 (3G nA, 3D tc).

The IP67 protection level and the rated temperature range of -25°C to +85°C ensure reliable use in outdoor environments.
