Festo
540012
Vacuum generator OVEM-07-H-B-GO-CE-N-2N
The Festo part number 540012 is a modular industrial component featuring a 0.7 mm nominal width Laval nozzle, a 20 mm width dimension, an open muffler construction type, and any mounting position. It incorporates an ejector pulse valve, flow control valve, electric on-off valve, filter, electric air-saving function, check valve, open muffler, and a vacuum switch with high vacuum and standard ejector characteristics. The unit includes a piezoresistive measuring principle for relative pressure, short-circuit and reverse polarity protection across all electrical connections, a 40 µm grade of filtration, and a backlit LCD 4-digit alphanumeric display with a -0.999 bar to 0 bar display range in bar units. Additional specifications feature non-detenting manual override via control keys, NC or N.O. switching element functions with window or threshold value comparator modes, a closed valve function, and switching inputs conforming to IEC 61131-2.
