Description

Award-winning in design and functionality

The successful design and the excellent functionality of the

WIKA switch family were already conrmed by winning the

“iF product design award 2009” for the PSD-30 pressure
switch.

The robust 14 segment LED display has been designed
using 0.35in (9 mm) high characters and with a slight incline
in order to make reading the 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 uid 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.

Electronic pressure switch, model PSD-30

Customised installation

The installation of the model PSD-30 and PSD-31 can be

exibly adapted 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.

High quality

During development of the WIKA switch family a high value
was placed on a robust design and the selection of appropri­ate materials suited for machine-building applications. For this
reason the case and the threaded connection of the electrical
connector are made from stainless steel. Overwinding or

tearing o the connector is therefore virtually impossible.

IO-Link

With the optional output signal in accordance with the IO-Link
communication standard, the PSD-30 and PSD-31 allow a
fast integration into modern automation systems. IO-Link

oers an even faster installation, parameterisation and higher

functionality of the model PSD-30 and PSD-31.
