Festo
540023
Vacuum generator OVEM-10-H-B-QO-CE-N-1P
The Festo 540023 is a modular industrial component featuring a 0.95 mm nominal width Laval nozzle, a 20 mm width dimension, an open muffler construction type, and any mounting position. It provides high vacuum and standard ejector characteristics, a 40 µm grade of filtration, a non-detenting manual override, and integrated functions including an electric ejector pulse valve, flow control valve, electric on-off valve, filter, check valve, open muffler, and vacuum switch. Equipped with piezoresistive relative pressure measurement, an N.O. contact switching element function, threshold value comparator and fixed hysteresis switching functions, LED display, LED switching position indication, teach-in setting options, and short-circuit and reverse polarity protection for all electrical connections with switching input to standard IEC 61131-2, this closed valve function unit operates with a relative pressure measured variable.
