Leading in design and functionalityThe model PSD-4 pressure switch represents the extensive further development of the PSD-30 pressure switch, itself already awarded with the “iF product design award” for its outstanding functionality. A high accuracy of 0.5 %, freely configurable output signals (PNP/NPN, 4 ... 20 mA/0 ... 10 V), the 5:1 scalability of the analogue output, in addition to outstanding self-diagnostics, make the PSD-4 an excellent automation solution.Customised installationThe installation of the PSD-4 can be flexibly adapted to the individual mounting situation. Due to the almost unlimited rotation of the digital display and case by more than 300°, the digital display can be adjusted independently of the electrical connection. The digital display can thus always be aligned to face the operator, and the M12 x 1 connection positioned to suit the desired cable routing.High qualityDuring development of the WIKA switch family a high value was placed on a robust design and the selection of appropriate materials suited to machine-building applications. For this reason the case and the threaded connection of the electrical connector are made from stainless steel. Overwinding or tearing off the connector is therefore virtually impossible.IO-Link 1.1With the optional output signal in accordance with the IO-Link communication standard, the PSD-4 allows a fast integration into modern automation systems. IO-Link offers simpler and faster installation, parameterisation and higher functionality for the PSD-4.
