The IFM PN7570 is a rugged electronic pressure sensor with an integrated digital display designed for fast set-up, clear on-machine status indication, and reliable switching in hydraulic and pneumatic systems. It covers a wide measuring range (0…400 bar) with high overload and burst margins, offers two fully programmable switching outputs (configurable as PNP/NPN, NO/NC), and exposes process data via IO-Link on one channel for modern PLC integration. The rotatable display head and G 1/4 process connection make installation straightforward even in tight panels or manifolds.

Key advantages at a glance

• Wide range + strong safety margins: 0…400 bar measuring range with approx. 800 bar rated pressure and ~1700 bar burst pressure for confidence in demanding hydraulic circuits.

• Fast, flexible switching: Two independent switching outputs; each can be set as PNP or NPN and as NO or NC. One output also provides IO-Link for parameterization and cyclic process data.

• Clear visibility on the machine: Bright 4-digit red/green display for instant “in/out-of-range” feedback; housing rotates ~345° so the screen faces the operator after tightening the process port.

• Tough construction: Stainless-steel wetted parts, IP65/IP67 protection, and gold-plated system contacts deliver durability in oils, coolants, air, and inert gases.

• Proven metrology: Typical accuracy around ±0.5% of span with repeatable switching; well-suited to machine protection and control tasks.

Technical specifications (PN7570)

What this means on your machine

Hydraulics and presses. The PN7570’s 400 bar span covers typical working pressures in metal-forming, injection molding, and clamping circuits. High overload/burst ratings protect the measuring cell from pressure spikes during valve switching or cold starts, reducing unplanned downtime. The dual outputs let you implement staged alarms (e.g., “warning” and “trip”) without extra relays, while IO-Link gives the PLC a clean digital readout for trending.

Pneumatics and compressors. Even in air systems far below the 400 bar ceiling, the same device can handle main header pressure control, receiver tank protection, and compressor interlocks. The display’s red/green logic makes it obvious when the line is within limits—useful for operators glancing into a cabinet.

Pumps and filtration skids. With IP65/IP67 sealing, stainless housing, and −25…+80 °C media capability, the PN7570 lives comfortably in coolant, cutting fluid, and water-glycol loops. IO-Link can expose raw pressure, switching states, and device diagnostics to your SCADA for predictive maintenance.

Integration highlights

• Parameterization without guesswork. Set SP/rP (setpoint/reset) directly on the head or via IO-Link; the sensor supports programming across the full range with well-defined increments so you can tune hysteresis for pump anti-short-cycle or valve chatter suppression.

• Flexible wiring. Each output can be PNP or NPN and NO or NC—handy when retrofitting mixed panels. The M12 connector simplifies swapping spares.

• Clean, readable mounting. Tighten the G 1/4 port to the correct torque, then rotate the head up to ~345° so the display faces the aisle. No awkward mirror reading through cabinet doors.

Why choose the PN7570 for new builds and retrofits

• One part number, many tasks. A single device family covers from vacuum (down to −1 bar) through high-pressure hydraulics; spare-stock planning gets simpler.

• Modern data with legacy compatibility. You get IO-Link for Industry 4.0 projects and straightforward discrete switching for older I/O cards—both in one unit.

• Operator-centric design. The red/green display is immediately understandable on the shop floor, and the rotating head solves the “beautifully wired, unreadable display” problem.

• Built to survive. High pressure margins, stainless steel construction, and IP65/67 protection mean fewer sensor casualties from pressure spikes, coolant splash, or accidental knocks.

Ordering and compatibility notes

The IFM PN7570 is commonly referenced as PN-400-SEG14-QFRKG/US//V; regional suffixes and accessory kits (adapters, seals) can vary by market. For the best fit, match your process connection (G 1/4), voltage (18…30 V DC), I/O style, and any required approvals to your site standards. If you standardize on IO-Link, confirm master compatibility and parameter blocks per your PLC platform.

In summary: The IFM PN7570 combines wide-range pressure monitoring, dual configurable switching, IO-Link data, and a clean, rotatable display in a compact, stainless package. It’s a practical drop-in for hydraulic power units, compressor skids, tool changers, test rigs, and OEM machinery that need robust switching and modern diagnostics without redesigning the control cabinet.
