IFM PN7094 Pressure sensor with display

Buy online your IFM PN7094 Pressure sensor with display from our UK e-store Cnc-shopping UK, specialist in CNC machine-tools spare parts.

The IFM electronic PN7094 is a compact electronic pressure sensor with an integrated digital display, designed for pressure monitoring and switching in CNC machines and industrial automation systems. It provides reliable electronic signals to PLCs and CNC I/O, supporting the control of hydraulic, pneumatic, coolant, and lubrication circuits.

Equipped with a front display and two programmable switching outputs, the PN7094 allows technicians to read pressure values directly on the machine, simplifying setup, troubleshooting, and maintenance. Typical applications include hydraulic clamp monitoring, pneumatic actuator supervision, coolant pressure control, spindle chiller verification, and lubrication line monitoring.

The sensor operates with a pressure range up to 10 bar and offers excellent overload resistance. It features a G 1/4 process connection, an M12 connector, and a high IP65/IP67 protection rating, making it suitable for demanding industrial environments exposed to coolant splash and oil mist.

Manufactured in Germany, the PN7094 is an ideal solution for retrofit and replacement projects when the original process connection, pressure range, and switching logic match the existing installation. It can also serve as a replacement for the PB7024, PN7024, and PN7004 pressure sensors.

Maintenance teams frequently use this model to resolve faults caused by low clamping pressure, unstable coolant pressure, or pneumatic supply issues. Keeping a spare unit in stock helps reduce unexpected downtime, while the clear display enables quick verification of setpoints after installation.

Each sensor supplied by Cnc-shopping can be tested by qualified engineers using appropriate instrumentation benches or simulators, carefully packaged for industrial shipping, and provided with applicable warranty coverage. Repair, exchange, and obsolete-part sourcing services are also available to help keep legacy CNC equipment operating reliably.

Frequently asked questions about PN7094:

Can PN7094 replace a failed pressure switch on a CNC hydraulic unit?
Yes, it is often used as a replacement unit. Verify the process connection, permissible pressure range and output logic against your original part to ensure a direct fit without rewiring the control side.

Where is this device typically mounted on machine-tools?
Common locations include the hydraulic power pack outlet, drawbar clamp circuit, pneumatic manifolds for tool changers and the discharge of the coolant pump. It is also used on lubrication headers to confirm minimum pressure.

How does the front display help maintenance technicians?
The display shows live pressure values at the point of measurement, which speeds up fault tracing and setpoint checks after a changeout. It allows quick confirmation that the circuit is within the required pressure window before releasing the machine back to production.

What should be checked before ordering as a drop-in spare?
Confirm the mechanical connection on the process side, the required measuring range, the switching output type expected by your PLC or CNC and the supply wiring. Matching these items ensures a smooth field replacement with minimal downtime.
