The IFM PN2094 is an electronic pressure sensor with an integrated 4-digit display for industrial pressure monitoring. It measures relative pressure and vacuum from -1 to 10 bar and is suitable for liquids and gases. Two programmable switching outputs and configurable analogue output functions provide flexible integration into automation systems. IO-Link communication enables digital parameterisation, diagnostics, and process-data access. Its ceramic-capacitive measuring cell, stainless-steel construction, and IP65/IP67 protection provide dependable industrial operation.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The PN2094 provides a measuring range of -1…10 bar for applications requiring both vacuum and positive-pressure monitoring. Its ceramic-capacitive pressure measuring cell provides stable measurement performance. The sensor supports configurable switch points and reset points for automated pressure control. High overload capability provides additional protection against pressure peaks. This makes the PN2094 suitable for hydraulic, pneumatic, and general industrial systems.
The integrated 4-digit red/green alphanumeric display provides clear pressure information at the installation point. Three green LEDs indicate the selected pressure unit, while yellow LEDs indicate switching status. IO-Link 1.1 enables digital parameterisation and process-data communication. The sensor supports a minimum IO-Link process cycle time of 2.3 ms in the standard configuration. This simplifies commissioning, diagnostics, and integration with PLC systems.
The PN2094 has a cylindrical stainless-steel housing with a G1/4 internal process connection. Its wetted parts include stainless steel, ceramic, and FKM sealing materials. The sensor is rated IP65 and IP67 and withstands shock and vibration according to its specified test conditions. The upper housing can be rotated 345° to improve display orientation. Gold-plated M12 contacts provide a reliable electrical connection.

The G1/4 internal thread allows installation into compatible industrial pressure ports. The 345° rotatable housing makes the display easier to orient after installation. Programming can be performed using the integrated button or through IO-Link. The display provides immediate local visibility of pressure and switching status. This combination simplifies commissioning and routine operation.
The PN2094 can provide switching signals, analogue values, and IO-Link process data. This allows the same sensor to support simple pressure alarms and advanced PLC-based monitoring. Configurable damping and switching delays help adapt the sensor to dynamic pressure systems. IO-Link also provides device identification and diagnostic information. The result is flexible pressure monitoring for modern industrial automation.
