The IFM PN7572 is a high-pressure electronic sensor with an integrated 4-digit red/green display for industrial pressure monitoring. It measures relative pressure from 0 to 100 bar and is designed primarily for liquid applications. Two programmable switching outputs provide flexible pressure-control functions, while IO-Link enables digital parameterisation and diagnostics. Its metallic thin-film measuring cell, stainless-steel construction, and 300 bar pressure rating support demanding industrial applications. The 345° rotatable housing allows convenient alignment of the display after installation.

The PN7572 provides a 0…100 bar pressure measuring range for high-pressure industrial systems. Its pressure rating is 300 bar with a minimum burst pressure of 1000 bar. Set points can be configured from 1 to 100 bar with 0.5 bar increments. The sensor also provides programmable hysteresis and window functions. This makes it suitable for pressure alarms, machine protection, and automated control.
The integrated red/green 4-digit display provides direct visibility of measured pressure. Three green LEDs identify the selected pressure unit, while two yellow LEDs indicate switching status. The upper housing can rotate 345° for improved display orientation. Programming can be performed using the integrated button. This provides convenient local configuration without requiring external equipment.
The PN7572 supports IO-Link 1.1 through COM2 at 38.4 kBaud. Both standard SIO operation and IO-Link communication are available. The minimum IO-Link process cycle time is 2.3 ms in the standard operating mode. High-resolution operating mode provides 0.05 bar IO-Link pressure resolution. Digital communication enables parameterisation, diagnostics, and process-data access.

The two switching outputs allow the PN7572 to monitor separate pressure thresholds. Hysteresis or window switching can be selected according to the application. Switch-on and switch-off delays can also be configured. This provides flexibility for pressure alarms and automated machine protection. The response time is below 3 ms.
Install the PN7572 through its G1/4 external process connection. Use the recommended 25…35 Nm tightening torque depending on sealing and installation conditions. The sensor housing can be rotated 345° for convenient display positioning. Ensure that pressure remains within the specified rating during operation. Inspect the process connection and M12 connector periodically.
