IFM PQ3834 Pressure Sensor with IO-Link

Product Introduction

The IFM PQ3834 is an advanced pressure sensor designed for precise monitoring and control in pneumatic and industrial systems. With a measuring range of -1 to 10 bar (-15 to 145 psi), it offers configurable outputs (switch signal, 4–20 mA analog, IO-Link) and exceptional accuracy (<±0.5% of measurement range). Featuring a robust PBT housing with IP65 protection, the sensor withstands harsh environments and provides reliable performance in applications requiring high precision and durability.

Product Features

Configurable Output Options:

1 digital output (PNP, configurable NO/NC) and 1 analog output (4–20 mA, 500 Ω max load).
