ifm efector PQ compact pressure sensor series with NPN circuit

Suitable for pneumatic applications in robotics and handling, ifm efector’s PQ compact pressure sensor series is now equipped with NPN circuit. Using a sealed measuring cell, these sensors detect the pressure in the vacuum and overpressure range.

The piezoresistive silicon cell measures, depending on the selected unit, between -1 and 10 bar or -1 and 1 bar. Due to the special sealing of the measuring cell, the pressure sensors are insensitive to liquids such as condensed water and deposits that might occur in the system. The sensors have good overload resistance and an accuracy of < ±0.5%.

The sensors’ slanted 4-digit display can be electronically rotated by 180° and read at a distance, from the front or from above. The display colour is selectable, with a green display colour for the acceptable range and red when the switching point is exceeded or not reached. Two programmable switching outputs or one switching output and one diagnostic output provide flexible use.

The sensors are easy to install by means of integrated mounting holes; a range of accessories is available for this.

The NPN circuit makes the unit suitable for exportation.
