The air checker, PS1 series, electronic pressure switch is available for positive pressure and for vacuum. PS1 is extremely compact and lightweight. Dimensions are 13W X 10H X 30L (mm) for standard type without connection part. A 2-wire switch is applicable to either NPN or PNP output. The plug-in reducer port for one-touch fittings makes the PS1 series easy to mount, and the large LED display provides a highly visible switch.
