IFM PN2699 is a compact electronic pressure sensor with an integrated red/green alphanumeric display, designed for reliable monitoring of relative pressure and vacuum in industrial fluid and pneumatic systems. It sits in that sweet spot where you want local, at-a-glance visibility at the machine and clean integration into a controller or condition-monitoring setup. The combination of multi-output flexibility, rugged mechanical design, and IO-Link communication makes it a strong “standardize-across-lines” candidate for OEMs and maintenance teams who are tired of juggling too many sensor variants.
At its core, the PN2699 uses a ceramic-capacitive measuring cell and supports a measuring range of -1 to +1 bar (also presented as -100 to +100 kPa, among other units), suitable for many common compressed-air, vacuum handling, and light hydraulic or process applications where you need dependable accuracy without oversizing the instrumentation. The wetted materials and robust housing are engineered for real industrial service, and the device is specified for media such as liquids and gases within a medium temperature window of roughly -25 to +80°C.
One of the defining strengths of the PN2699 is how it lets you choose your integration style. You get two digital switching outputs plus one analog output, with the output signal configurable to support classic switching, analog, and IO-Link use cases. The electrical design supports PNP/NPN operation and offers parameterizable switching modes (NO/NC), which is a practical advantage in mixed fleets or multi-region machine builds. On the analog side, the sensor provides 4–20 mA and 0–10 V options (with scalable ranges), giving you compatibility with a wide swath of PLC and analog input standards. Supply is 18–30 V DC, with low current consumption, consistent with modern sensor islands and distributed I/O architectures.
The display experience is more than a nice gimmick. The red/green indication helps operators and technicians immediately recognize whether the measured pressure is within an acceptable window. This is particularly useful in setups where pressure stability is a quality gate—think vacuum pick-and-place, packaging lines, leak testing stations, and pneumatic tooling where a fast visual diagnosis can prevent downtime. The upper housing can be rotated for better viewing angles, supporting tighter installation spaces.
In dynamic systems, response characteristics matter. The PN2699 specifies a fast response time (on the order of milliseconds), which helps when you’re dealing with rapid pressure fluctuations or short cycle times. At the same time, the device offers parameterizable damping and delay functions, allowing you to tune out nuisance spikes without losing control relevance—an underrated feature that can reduce false alarms in real factories.
From a maintenance and digitalization perspective, IO-Link is where the PN2699 becomes a forward-looking asset. With IO-Link you can read not only pressure values but also device status and diagnostics, and you can manage parameter sets centrally. This reduces commissioning time and makes sensor replacement far less error-prone—swap the unit, push the saved parameter profile, and get back online with minimal fiddling. The PN2699 supports IO-Link revision 1.1 and Smart Sensor profiles, aligning with contemporary interoperability expectations.
Mechanically, the PN2699 has a 1/4" NPT external thread process connection and a compact cylindrical form factor. Protection ratings of IP65/IP67 and tested shock/vibration resistance are aligned with harsh industrial environments. The unit’s weight is around 246 g, making it easy to mount on brackets, manifolds, or machine panels without demanding heavy-duty supports.

Practical Buying/Specification Notes
When specifying PN2699, confirm the process thread standard (1/4" NPT) matches your region and piping practice, and verify your control architecture’s preferred signal type (IO-Link vs 4–20 mA vs 0–10 V). If you are standardizing across plants, the PN2699’s configurable output logic and PNP/NPN flexibility can reduce SKU sprawl and simplify inventory strategy.
Overall, the IFM PN2699 is a modern, highly adaptable pressure sensor that blends operator-friendly visualization with industry-standard electrical and digital interfaces. It’s a practical choice when you want one device to serve both the human eye at the machine and the data needs of a smarter, more diagnosable automation system.
