IFM PN2093 Pressure Sensor – PN-025-RER14-MFRKG/US/ /V

The IFM PN2093 is a ceramic-capacitive pressure sensor engineered for industrial pressure and vacuum measurement in systems handling liquids and gases. With a measuring range of –1 to 25 bar, dual switching outputs, a scalable analogue signal, and IO-Link connectivity, it provides reliable and flexible integration into modern control systems—even under high pressure, vibration, or shock conditions.
