Product Overview
The ifm PN7094 is a compact electronic pressure sensor designed for monitoring liquids and gases in industrial machinery. It combines a ceramic-capacitive measuring cell, two configurable switching outputs, IO-Link communication and a highly visible four-digit red/green display.
The display colour can indicate whether the measured pressure is within the acceptable operating range, allowing technicians to identify abnormal conditions quickly.

Important Ordering Checks
Before supplying the PN7094, confirm:
- Required range is −1 to 10 bar
- G 1/4 female process connection is suitable
- System uses an 18–30 VDC supply
- PNP or NPN output configuration
- Required switching or IO-Link operation
- Medium compatibility with 316L stainless steel, ceramic and FKM
- M12 mating cable or connector requirement
- Hazardous-area certification requirement
- Marine or classification approval requirement
Important: PN7094 provides two switching outputs and IO-Link. It does not provide a conventional 4–20 mA analogue output.
