Recision New Original Pressure Sensor With Display IFM PN2599 Perfect Performance for Industrial Control

The IFM PN2599 is a compact, programmable pressure sensor with an integrated 4-digit red/green display, built for dependable monitoring of relative pressure and vacuum in industrial automation. It’s aimed at the real-world sweet spot where you want a rugged sensor that can live on a machine for years, provide instant local readability, and still integrate cleanly into modern control networks. The PN2599 belongs to IFM’s PN series with digital display, emphasizing usability, long-term stability, and flexible output configuration for both OEM designs and maintenance-driven retrofits. 

Why PN2599 is a practical “standard” low-pressure/vacuum choice

Many factories need a pressure device that covers everything from vacuum pick-up to pneumatic supply verification and light process applications. The PN2599’s measuring range of -1 to +1 bar (also shown as -1000…+1000 mbar, -100…+100 kPa, and other unit equivalents) makes it especially suitable for compressed air and vacuum domains where you want one sensor family to handle multiple stations with minimal engineering overhead.

The sensing technology is a ceramic-capacitive pressure measuring cell, known for robustness and consistent performance in industrial conditions. IFM positions this design for use with liquids and gases, which broadens the PN2599’s applicability beyond pure pneumatics. The rated medium temperature range of approximately -25 to +80°C is aligned with typical machine environments and plant utilities.

Human-friendly display that also supports fast troubleshooting

The PN2599’s red/green alphanumeric display is not just cosmetic. It’s part of a simple but effective operator-feedback strategy: you can configure acceptable ranges so the display color makes an out-of-range condition obvious even at a quick glance. This is useful on equipment where pressure drift directly correlates with scrap risk, cycle instability, or vacuum drop-off. The upper housing can be rotated (up to about 345°) to improve readability in tight mechanical layouts. 

Output flexibility: switching, analog, and IO-Link

The PN2599 offers a modern integration toolkit. It provides two switching outputs and one analog output, with one switching channel programmable for IO-Link use and the other supporting classic digital switching; the analog channel can be configured for 4–20 mA or 0–10 V with scalable ranges. This matters in mixed facilities where some machines are legacy PLC systems and others are digitized cells with IO-Link masters. You can standardize the hardware and simply adjust parameters at commissioning. 

The electrical design supports PNP/NPN operation, with programmable NO/NC behavior and common parameter options like hysteresis or window functions. The sensor runs on 18–30 V DC and has low current consumption, consistent with distributed I/O and compact machine architectures. 

For plants leaning into predictive maintenance or rapid changeovers, IO-Link revision 1.1 support is a meaningful advantage. It enables structured process data, device identification, and diagnostics, and it allows parameter sets to be stored and restored during sensor replacement. This reduces human error and helps new lines come online faster. 

Mechanical integration and durability

The PN2599 uses a G 1/4 external thread process connection (per DIN EN ISO 1179-2) and also includes an M5 internal thread option, giving you flexibility across manifold styles and compact pneumatic blocks. The sensor is designed for harsh environments with IP65/IP67 protection. Gold-plated contacts are listed as a special feature, supporting reliable connectivity over time, especially in vibration-prone or humidity-variable settings. 

The device is specified with substantial overload and bursting margins for its class, reinforcing IFM’s positioning of long-term stability and ruggedness in daily industrial use.

Application scenarios where PN2599 shines

The PN2599 is particularly effective in applications that need fast verification and stable low-pressure monitoring:

1. Vacuum handling and pick-and-place
   The -1…+1 bar span covers typical industrial vacuum ranges used in packaging, electronics assembly, and robotic end-of-arm tooling. The red/green display helps technicians confirm system health without plugging into a laptop. 

2. Pneumatic supply monitoring
   In assembly lines, consistent air pressure is a hidden quality driver. The PN2599’s switching outputs can be used to trigger alarms or interlocks, while the analog or IO-Link signal can feed trending in a PLC or edge gateway.

3. Compact machine modules and manifolds
   The G 1/4 and M5 connection options support dense mechanical integration. The rotatable head also reduces awkward cable routing and improves readability. 

Integration and commissioning tips

To get the best out of PN2599 in a multi-machine environment, consider a simple strategy: use IO-Link where available for parameter backup and diagnostics, and reserve analog output for legacy lines that still rely on standard 4–20 mA or 0–10 V signal chains. Because the sensor supports configurable output behavior and multiple units of measure, you can reduce spare parts complexity by standardizing on PN2599 across similar low-pressure/vacuum stations. 

Bottom line

The IFM PN2599 is a tough, flexible, operator-friendly low-pressure and vacuum sensor that bridges two worlds: classic, reliable switching and analog control and the more modern IO-Link diagnostic ecosystem. With a practical measuring range, ceramic-capacitive durability, and an intuitive red/green display, it’s a strong choice for OEM designs and for plants looking to modernize without turning every upgrade into a full controls rewrite.
