IFM PT5500 Pressure Sensor – PT-400-SEG14-A-ZVG/US

The IFM PT5500 is a compact, high-pressure analogue pressure sensor built for mobile and hydraulic applications requiring extreme robustness and precision. Designed for reliable operation up to 400 bar (5800 psi) with an integrated restrictor, the PT5500 offers fast 2 ms response time, 4–20 mA current output, and superior shock resistance up to 500 g. Engineered for harsh environments, it features IP69K protection, –40 to +125 °C medium tolerance, and is rated for up to 1700 bar burst pressure. With gold-standard EMC compliance and long service life, it’s ideal for demanding mobile machinery, OEM hydraulics, and compressed gas systems.
