PQ7834 Pressure Sensor for Pneumatics -1…10 bar PNP M12 | IFM

The Original New IFM PQ7834 Pressure Sensor for Pneumatics is a compact electronic pressure sensor designed for reliable monitoring of system pressure in pneumatic and compressed air systems. Featuring a piezoresistive measuring element, it provides precise measurement of relative pressure and vacuum. The sensor offers very high overpressure and vacuum resistance, a clearly visible slanted dual-colour LED display for clear identification of acceptable ranges, and two programmable PNP switching outputs (one configurable as a diagnostic output). Process connection via G 1/8 internal thread with gold‑plated contacts.

Core Engineering Highlights:
–1…10 bar measuring range | Two PNP switching outputs | G 1/8 internal thread | 18–32V DC operating voltage | <2.5 ms response time | IP65 protection | –0.5% switch point accuracy | Red/green dual‑colour LED display
