Festo
The Festo 162521 industrial component features a 2 mm nominal width Laval nozzle, a 22 mm width dimension, and a closed muffler construction type supporting any mounting position. This high-vacuum ejector integrates an electric on-off valve, a 40 µm grade filter, and a piezoresistive vacuum switch measuring relative pressure with a closed valve function, N.O. contact switching element function, and threshold value comparator switching function. It incorporates reverse polarity protection across all electrical connections, an LED display, optical switching status indication, non-detenting manual override, and potentiometer setting options providing a threshold value setting range of -90 kPa to 0 kPa and a hysteresis setting range of -50 kPa to -5 kPa.

Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
For a faster response, include quantity, condition, and delivery destination.
