The successful design and the excellent functionality of the WIKA switch family were already confirmed by winning the “iF product design award 2009” for the pressure switch model PSD-30.

The robust 14 segment LED display has been designed using 0.35 in (9 mm) high characters and with a slight incline in order to make reading the prevailing pressure as easy as possible from a distance.

The 3-key operation makes simple, intuitive menu navigation possible, with no need for additional assistance. The menu navigation conforms to the latest VDMA standard.

The VDMA standard for fluid sensors (24574-1, part 1 - pressure switches) has the aim of simplifying the use of pressure switches by standardising menu navigation and display.

The control keys have been designed as large as possible and are arranged ergonomically to ensure fast and easy adjustments. Operation without any additional assistance is made easier through the tactile feedback.

The installation of the model PSA-31 can be flexibly adapt- ed to the individual mounting situation. Due to the almost unlimited rotation of the display and case by more than 300°, the display can be adjusted independently of the electrical connection.

The display can thus always be aligned to face the operator, and the M12 x 1 connection positioned to suit the desired cable routing.

During development of the WIKA switch family a high value was placed on a robust design and the selection of appro- priate materials suited for machine-building applications.

For this reason the case and the threaded connection of the electrical connector are made from stainless steel. Overwind- ing or tearing off the connector is therefore virtually impossible.

With the optional output signal in accordance with the IO-Link communication standard, the PSA-31 allows a fast integra- tion into modern automation systems.

IO-Link offers an even faster installation, parameterisation and higher functionality of the model PSA-31.
