Electronic pressure switch NAT 8252

The miniature pressure switch NAT 8252 are available with 1 or 2 switching outputs (PNP). The maximum switching current of 400 mA in total of both outputs is tolerable within the temperature range of -40..+85°C. Over the entire temperature range of -40..+125°C, the maximum switching current is 200 mA in total of both outputs.

The switching outputs include the functions hysteresis and window with the option normally open and normally closed. A delay time is provided for each switching output. For the 2nd switching output is a monitoring mode “Device Ready” available. In this mode the output changes the state if the device has successfully completed the start-up phase. In case of an error during operation the status will change back to the normal state.

The standard electrical connection for electronic pressure switches according to VDMA 24574-1 is the built in M12x1 connector. The accuracy 0,5% with temperature compensation and linearization is available. The miniature pressure switch are readily available in the pressure range 0..2,5 to 0..600 bar.
