The IFM PN7094 is an electronic pressure sensor with a 4-digit red/green display for industrial pressure monitoring. It measures -1…10 bar and is suitable for liquids and gases. Two programmable switching outputs provide flexible pressure-control functions, while IO-Link enables digital parameterisation and diagnostics. The ceramic-capacitive measuring cell provides reliable pressure measurement with high overload resistance. Its G1/4 internal thread, M12 connector, and IP65/IP67 protection make it suitable for industrial machinery and automation systems.

The PN7094 covers a pressure range from -1 to 10 bar. Both positive pressure and vacuum conditions can therefore be monitored. The ceramic-capacitive measuring cell provides stable measurement performance. Switch points can be programmed according to the required pressure limits. This makes the sensor suitable for machine protection and process control.
Two digital outputs can be configured as normally open or normally closed. PNP/NPN electrical design allows compatibility with different control architectures. The sensor supports a switching frequency below 170 Hz. Short-circuit and overload protection are included. This provides flexible and reliable pressure switching for automated equipment.
The PN7094 supports IO-Link 1.1 with COM2 communication at 38.4 kBaud. Standard operation can also be performed through SIO mode. Pressure data can be transferred digitally to a compatible IO-Link master. The sensor supports both standard and high-resolution operating profiles. This simplifies configuration and provides better visibility of sensor operating conditions.

The integrated programming button allows pressure parameters to be configured locally. The 4-digit display provides clear pressure and unit information. The upper housing can rotate through 345° for improved visibility. Green and yellow LEDs provide additional operating and switching indications. This makes commissioning and routine monitoring straightforward.
The PN7094 uses a stainless-steel cylindrical housing with ceramic and FKM wetted materials. It supports a 75 bar pressure rating and 150 bar minimum burst pressure. The sensor operates from 18…30 V DC. IP65/IP67 protection provides resistance against dust and water ingress. Its 100-million pressure-cycle rating supports long-term industrial use.
