The miniature pressure switch NAH 8254 is available with 1 or 2 switching outputs (PNP). The maximum switching current of 400 mA in total for both outputs is tolerable within the temperature range of -40 to +85°C. Over the entire temperature range of -40 to +125°C, the maximum switching current is 200 mA in total for both outputs.
The switching outputs include hysteresis and window functions with the options of normally open and normally closed. A delay time is provided for each switching output. For the 2nd switching output, a monitoring mode “Device Ready” is available. In this mode, the output changes state if the device has successfully completed the start-up phase. In case of an error during operation, the status will revert to the normal state.
The standard electrical connection for electronic pressure switches according to VDMA 24574-1 is the built-in M12x1 connector. An accuracy of 0.3% with temperature compensation and linearization is available. The miniature pressure switch is readily available in the pressure range of 0 to 2.5 bar up to 0 to 600 bar.
